Plant diversity and endemism in China: unreachable locations and diverse microclimates

The newly described Bulbophyllum reflexipetalum

A new issue of the scholarly, open-access and peer-reviewed journal PhytoKeys focuses on the Chinese biodiversity hotspots and their substantial role in understanding the country’s unique flora. The special issue embarks on a treasure hunt into China’s biodiversity hotspots, including the descriptions of 23 species previously unknown to science and new insights into the ecological diversity of ferns based on their DNA sequences.

In China, biodiversity-rich landscapes vary from the dry Northwest region, through the surrounded by massive mountain ranges of the Qinghai-Tibet Plateau, to the tropical and subtropical southern China. The combination of remote and hard to reach mountain areas and diverse microclimates promises high levels of endemism.

“With extended collaboration among Chinese scientists and coordination of networks on plant conservation and taxonomy across China, we synthesize a special issue entitled “Revealing the plant diversity in China’s biodiversity hotspots”, to present the latest findings by Chinese botanists, and to update knowledge of the flora for China and adjacent countries”, explained De-Zhu Li, professor of botany at Kunming Institute of Botany (KIB), Chinese Academy of Sciences (CAS), in the editorial.

Among the newly described species, four new members of the African violet family were found from a subtropical forest in Yunnan province in southern China, discovered by researchers from Xishuangbanna Tropical Botanical Garden, CAS and their collaborators. Half of them were found only from a sole population and require further botanical examinations to deploy the conservation priorities, remark the scientists.

In another paper, scientists Yun-Feng Huang and Li-Na Dong and Wei-Bin Xu, representatives of Guangxi Institute of Botany, revealed the discovery of a new species from the primrose family. Found nowhere outside the limestone areas in Liucheng county (Guangxi, China), this rare plant species is currently facing serious threats of extinction because of the fragility and sensitivity of its habitat to the environmental changes associated with the rapid economic development of China.

Another team from the Guizhou University of Traditional Chinese Medicine and KIB describes a new representative of the parachute flowers. Ceropegia jinshaensis, characterized by the shape and size of its leaves and flowers.

“More conservation efforts are needed in this region to counteract the increasing anthropogenic disturbance and destruction”, state the leading authors from KIB, who discovered a new species of orchid in the Eastern Himalaya biodiversity hotspot.

The special issue features the description of additional two orchid species, discovered in Motuo, located at the Himalayan border between China, Myanmar and India. The region is well known for its vertical vegetation system, varying from tropical forest to permanent glaciers. Ji-Dong Ya and Cheng Liu from the KIB and Xiao-Hua Jin from the Institute of Botany, CAS underline that the difficult access to the area allows the thriving and diversification of plants.

Scientists challenge notion of binary sexuality with naming of new plant species

A collaborative team of scientists from the US and Australia has named a new plant species from the remote Outback. Bucknell University biology postdoctoral fellow Angela McDonnell and professor Chris Martine led the description of the plant that had confounded field biologists for decades because of the unusual fluidity of its flower form. The discovery, published in the open access journal PhytoKeys, offers a powerful example of the diversity of sexual forms found among plants.

The new species of bush tomato discovered in remote Australia provides a compelling example of the fact that sexuality among Earth’s living creatures is far more diverse – and interesting – than many people likely realize.

Bucknell University postdoctoral fellow Angela McDonnell and biology professor Chris Martine led the study following an expedition last year to relocate populations of the new plant, which were first noted by Australian botanists during the 1970s.

Herbarium specimens from those few earlier collections are peppered with notes regarding the challenge of identifying the sexual condition of this plant, which appeared at various times to be female, male, or bisexual.

According to Martine, about 85% of the planet’s quarter-million flowering plant species have flowers that are bisexual – with both male and female organs present in every blossom.

“So that’s already quite different than what some people might expect; but the remaining 15% or so come in all sorts of forms that push the envelope further, including unisexual flowers and (like we see in a plant like Cannabis) whole plants that are either male or female.”

“For the most part, a given plant species will stick to one primary and predictable type of sexual expression,” said Martine “but what makes Solanum plastisexum stand out is that it is one of a just a few plants that kind of do it all. It really seems like you never know what you’ll get when you come across it.”

When DNA studies in Martine’s lab offered proof that these plants were not only all the same thing, but a species not yet described, he, McDonnell, Jason Cantley (San Francisco State University), and Peter Jobson (Northern Territory Herbarium in Alice Springs) set out to hunt for populations along the unpaved Buchanan Highway in the remote northwestern region of the Northern Territory.

The botanists were able to collect numerous new specimens and have now published the new species description in the open-access journal PhytoKeys, choosing the name Solanum plastisexum as a nod to the notable variation exhibited by this plant in its sexual condition.

“This name, for us, is not just a reflection of the diversity of sexual forms seen in this species,” wrote the authors in the article. “It is also a recognition that this plant is a model for the sort of sexual fluidity that is present across the Plant Kingdom – where just about any sort of reproductive form one can imagine (within the constraints of plant development) is present.”

Also known as the Dungowan bush tomato, Solanum plastisexum is a distant cousin of the cultivated eggplant and is a close relative of two other Australian species recently discovered by Martine and colleagues that were also published in PhytoKeys: Solanum watneyi, named for Mark Watney, the space botanist of the book/film The Martian; and Solanum jobsonii, a species named last year for S. plastisexum co-author Jobson.

The scientists hope that the naming of this latest new species turns a spotlight on the fact that nature is full of examples for the myriad ways in which living things behave sexually.

“In a way, S. plastisexum is not just a model for the diversity of sexual/reproductive form seen among plants – it is also evidence that attempts to recognize a “normative” sexual condition among the planet’s living creatures is problematic.”

“When considering the scope of life on Earth,” the authors conclude, “The notion of a constant sexual binary consisting of two distinct and disconnected forms is, fundamentally, a fallacy.”

New perennial brome-grass from the Iberian Peninsula named after Picos de Europa National Park

Picos de Europa National Park has given its name to a new species of perennial bromegrass, discovered in Spain. Bromus picoeuropeanus belongs to a rather underrepresented on the Iberian Peninsula perennial group within the grass genus Bromus, with the new species being just the fourth of all recognised wild species living in the Iberian territory.

Having worked on the systematics of Bromus for a long time, scientists Dr Carmen Acedo and Dr Félix Llamas, members of the Taxonomy and Biodiversity Conservation research group TaCobi of the Spanish University of León, were surprised to collect what seemed a so-far-unrecognised species of the rare for Iberia perennial group. The unlikely discovery of the new species was described and published in the open access journal PhytoKeys, while its type specimen is preserved on Herbarium LEB.

This is the preferred habitat of *Bromus picoeuropeanus* in stony and unstable soils, c. 1900 m elevation.

Failing to understand how it was possible that the new species has never been found in the over-studied territory of Picos de Europa National Park, the two researchers traveled back to the classic locality to confirm its presence and study the habitat. Interestingly, while the new species is located in a typical for the National Park habitat, only a single perennial Bromus species was previously known from the area.

Eventually, having spent more time studying and collecting samples of different taxa in the Park, the authors discovered several more individuals of the new species dwelling in stony areas at an altitude of 1600 – 2200m. While herbarium collections from the National Park revealed that samples were also collected some years ago by another botanist, the scarcity of populations of the new species is still striking given the abundance of other brome-grass species.

Unlike its sister species, the Picoeuropean brome-grass is a small rhizomatous herb up to 70 cm high. Another easy-to-recognize difference is its well-developed subterraneous vegetative organ, forming a long rootstalk called rhizome, which is an easy distinctive trait.

“Given the inaccessibility of the areas, the mountainous topography and the few grass-species-loving botanists, this species was ignored until now. Probably the genus Bromus has undergone some local speciation on this isolated place, but exactly how this occurred requires further investigation,” explain the authors noting the isolation of the new species from its relatives in the area.

FAIR biodiversity data in Pensoft journals thanks to a routine data auditing workflow

*Data audit workflow provided for data papers submitted to Pensoft journals.*

To avoid publication of openly accessible, yet unusable datasets, fated to result in irreproducible and inoperable biological diversity research at some point down the road, Pensoft takes care for auditing data described in data paper manuscripts upon their submission to applicable journals in the publisher’s portfolio, including Biodiversity Data Journal, ZooKeys, PhytoKeys, MycoKeys and many others.

Once the dataset is clean and the paper is published, biodiversity data, such as taxa, occurrence records, observations, specimens and related information, become FAIR (findable, accessible, interoperable and reusable), so that they can be merged, reformatted and incorporated into novel and visionary projects, regardless of whether they are accessed by a human researcher or a data-mining computation.

As part of the pre-review technical evaluation of a data paper submitted to a Pensoft journal, the associated datasets are subjected to data audit meant to identify any issues that could make the data inoperable. This check is conducted regardless of whether the dataset are provided as supplementary material within the data paper manuscript or linked from the Global Biodiversity Information Facility (GBIF) or another external repository. The features that undergo the audit can be found in a data quality checklist made available from the website of each journal alongside key recommendations for submitting authors.

Once the check is complete, the submitting author receives an audit report providing improvement recommendations, similarly to the commentaries he/she would receive following the peer review stage of the data paper. In case there are major issues with the dataset, the data paper can be rejected prior to assignment to a subject editor, but resubmitted after the necessary corrections are applied. At this step, authors who have already published their data via an external repository are also reminded to correct those accordingly.

“It all started back in 2010, when we joined forces with GBIF on a quite advanced idea in the domain of biodiversity: a data paper workflow as a means to recognise both the scientific value of rich metadata and the efforts of the the data collectors and curators. Together we figured that those data could be published most efficiently as citable academic papers,” says Pensoft’s founder and Managing director Prof. Lyubomir Penev.

“From there, with the kind help and support of Dr Robert Mesibov, the concept evolved into a data audit workflow, meant to ‘proofread’ the data in those data papers the way a copy editor would go through the text,” he adds.

“The data auditing we do is not a check on whether a scientific name is properly spelled, or a bibliographic reference is correct, or a locality has the correct latitude and longitude”, explains Dr Mesibov. “Instead, we aim to ensure that there are no broken or duplicated records, disagreements between fields, misuses of the Darwin Core recommendations, or any of the many technical issues, such as character encoding errors, that can be an obstacle to data processing.”

At Pensoft, the publication of openly accessible, easy to access, find, re-use and archive data is seen as a crucial responsibility of researchers aiming to deliver high-quality and viable scientific output intended to stand the test of time and serve the public good.

CASE STUDY: Data audit for the “Vascular plants dataset of the COFC herbarium (University of Cordoba, Spain)”, a data paper in PhytoKeys

To explain how and why biodiversity data should be published in full compliance with the best (open) science practices, the team behind Pensoft and long-year collaborators published a guidelines paper, titled “Strategies and guidelines for scholarly publishing of biodiversity data” in the open science journal Research Ideas and Outcomes (RIO Journal).

Aloe sanguinalis, a new red Aloe from Somaliland

Aloe sanguinalis, or Somali Red Aloe, forms large, conspicuous clumps and has blood red sap. Its can easily be spotted from the road, but the species has only just been named and described in the open access journal PhytoKeys.

It remains a mystery how this beautiful and showy aloe species has remained undescribed by science for so long, but one of the theory is that the plant was ‘hiding in plain sight’ in an area not usually known for its high biological diversity.

The locals in the area have long known that the plants were different from other kinds of “Dacar”, (the Somali name for Aloes) in the region and were referring to them as “Dacar cas” or “Red aloe”.

Similarly, the scientific name for the new species – Aloe sanguinalis – is based on one of its most distinct characters, its bright red color, coming from the peculiar blood-red sap the plant produces. The leaves also become reddish as they mature.

The story of the formal recognition of “Dacar cas” or Aloe sanguinalis, however, began when Ahmed Awale, a leading Somaliland environmentalist, spotted the large, reddish clumps plants, while driving through the country on behalf of Candlelight, an NGO focused on the environment, education, and health.

Later on, when the plant came to the attention of Mary Barkworth, a botanist interested in building botanical capacity in Somaliland. After listening to Ahmed, the two of them began looking formally into the possibility that “Dacar cas” was, indeed, an undescribed species. They were soon convinced it was. After the initial excitement, the next step required demonstrating that “Dacar Cas” differs from all the other 600+ known species of Aloe. That step took longer, but finally it has been done.

Aloe sanguinalis, or Dakar Cas, together with Ahmed Awale.

“This news comes from a region which had experienced periods of conflict and instability, climate change effects and accelerated environmental degradation, whereby much of the people’s attention has been focused on promoting livelihoods and resilience. With this positive piece of information we hope that we inspire scientists to further explore the area,” explains Dr Barkworth.

The new species is currently known from only two locations, but it is hoped that naming and sharing pictures of it online will encourage discovery and documentation of additional locations. Images and locality information for new locations are welcome at faisaljama24@gmail.com or mary.barkworth@usu.edu.

Brazil-endemic plant genus Mcvaughia highlights diversity in a unique biome

The small genus is found exclusively in the recently recognized Seasonally Dry Tropical Forests biome.

A new species of the Brazil-endemic small genus Mcvaughia is described as part of a extended revision of this unique group. The study was published in the open access journal PhytoKeys.

Mcvaughia is a genus of the plant family Malpighiaceae comprising just three known species, all of which endemic to the unique Seasonally Dry Tropical Forests biome found in the Atlantic Forest and Caatinga domains in northeastern Brazil.

In fact, Seasonally Dry Tropical Forests have only been recognized as a worldwide biome recently and taxonomic studies focusing on its endemic plant species are imperative for conservation management.

Mcvaughia sergipana – one of just 3 known representative of the small genus.

In their newly published monograph, the team of scientists from Universidade Federal de Minas Gerais, Universidade Federal de Viçosa, Universidade Federal do Amazonas, Universidad Nacional Autónoma de México & Smithsonian answer the need for a deeper understanding on this unique biome, starting with genus Mcvaughia and hoping to continue with other endemic plant groups in the future.

“We are truly fascinated by the members of this new and exciting biome and when during a visit in Brazilian herbaria, we found a third species of Mcvaughia endemic to seasonally dry forests from the state of Piauí, Brazil, we couldn’t miss the chance to improve knowledge on this unique genus and the biome where it is only found,” explains lead author, Dr Rafael F. Almeida from the Universidade Federal de Minas Gerais, Brazil.

The name of the newly described species Mcvaughia piauhiensis pays tribute to Dr. Rogers McVaugh, an American botanist, expert in the Mexican flora.

“The results presented in this study are the second step towards a complete taxonomic revision of the Mcvaughioid clade using several additional methods in biosystematics. The macro and micromorphological data presented here are promising for future taxonomic and phylogenetic studies focusing on understanding the morphological evolution in the Mcvaughioid clade, and in Malpighiaceae, as well,” conclude the authors.

Sticky and heavily armed, a tomato-relative is the new ‘star’ of the Brazilian inselbergs

Armed with long thorns and sticky stems, newly described plant Solanum kollastrummight look like a villain by plant standards, but a closer look on this curious new species will reveal its star-like nature in the context of its ecosystem.

Recently described in open access journal PhytoKeys, this newly discovered tomato relative boasts stems densely armed with prickles of up to 17 mm long and to 2.3 mm wide at the base.

In fact, the new species is baptised after yet another showy defence mechanism. The name kollastrum comes from the Greek words for glue and star, referring to the peculiar sticky hairs that end in a star-like formation.

Close-up of the unusual star-like shape of the sticky hairs’ protrusions along the stems of the new species.

While all this heavy armour might at first fool you that this new species lives in isolation, a closer look has revealed that, contrary to the expectations, S. kollastrum starts as the good guy in its ecosystem.

Field observations of the new species have suggested that it’s preferred by medium- to large-sized bees with buzzing behaviour. The fruit structure of S. kollastrum, with fruits hanging outside its foliage on long axes, along with the numerous relatively small seeds and the release of a mild sweetish scent, suggest that fruits eaten by bats.

The heavy armour is, in fact, not that unusual in the group of ‘spiny solanums’ to which the new species belongs. With approximately 110 species of spiny solanums, the Brazilian Solanum flora is exceedingly diverse.

In its own right, Solanum is an extremely diverse plant genus to which important crops such as potatoes, tomatoes and eggplants belong.

Endemic to eastern Brazil, the known records of the armed new species are mostly concentrated along the Mucuri River watershed, where it inhabits edge of small forest fragments. In fact, the species is especially seen in areas at the base or on the peculiar and gigantic geological formations known as inselbergs or ‘sugar loaves’). Some populations were also found in disturbed sites near these rock outcrops, such as borders of unpaved roads and pastures.

“The discovery of S. kollastrum, a robust and conspicuous plant growing at the roadsides in regions close to large urban centres, highlights how insufficiently known the Brazilian flora is,” explain authors from the Universidade Federal de Minas Gerais and Universidade Federal do Oeste do Pará, Brazil.

“This highlights how urgent the need is to describe, study and conserve the country’s plant diversity. Thus, we hope that this discovery encourages the study on the most diverse aspects of this species’ biology.”

An overlooked giant: useful and abundant, African ‘Zam’ palm newly described for science

Common sight along road sides in south Cameroon and western Gabon, and growing in hard-to-be-missed dense colonies, it remains a mystery how this locally useful new palm species Raphia zamiana (locally known as “Zam”) has been missed by botanists until now, with its first collection dating to 2012. The overlooked giant has been recently described in the open access journal PhytoKeys, alongside a shy and rare endemic from the same genus.

Curiously, it might have been exactly the large size of Raphia zamiana that has discouraged botanists from collecting and cataloguing this species, according to the multinational team of researchers from the University of Yaoundé, Cameroon, National Herbarium of Gabon, Gabon, the Conservatoire et Jardin botaniques – Ville de Genève, Switzerland, the Institut de Recherche pour le Développement, IRD, France.

While this theory might sound strange at first, it is plausible, given that a single leaf of this large palm can reach up to 21 meters long and forms dense colonies in swampy areas. Large leaves are not uncommon among the representatives of, what is known as the most diverse genus of African palms, Raphia, with one species, R. regalis, having leaves up to 25 meters, a record in the plant kingdom!

Newly described and named to science, this species is, just like many other representatives of the genus, well-known and heavily used across its range. Uses, of what is locally known as “Zam” include: timber, locally referred to as “bamboo”, used for construction, and fruits – for consumption and medicine. Finally, Zam is also used for wine tapping in certain parts.

“It is indeed incredible that such a large and useful palm has remained unknown to science until now,” comments author Thomas Couvreur, Institut de Recherche pour le Développement, IRD, France.

“This curious fact, however, underlines a bigger problem. While biodiversity is being destroyed at unprecedented rates, we still have a lot to discover and describe, even species that are common, well known and useful. This comes as a surprise to many people and underlines how much remains to be discovered in the tropics. Scientifically describing species, especially useful ones, is very important, as it “puts then on the map”, which allows them to be studied and managed. In this sense, field work remains key.”, concludes Thomas Couvreur.

Raphia gabonica in its natural habitat in Alèmbé, Gabon.

The need to further study and conserve this group of palms is evidenced by a second newly described species in the same PhytoKeys paper. Named after its country of origin, Raphia gabonica, is restricted to only two small populations from central Gabon, where it occurs on hillsides and along small rivers.

Right upon description, R. gabonica is already threatened by extinction. It was assigned a preliminary IUCN status of “Endangered”, because it is found in small unprotected pockets of forest along roadsides. It is now amongst the five most threatened palm species for the whole of Africa.

“Our study shows that, despite their economic and cultural importance across tropical Africa and for Africans, we still know too little about Raphia palms. This is very paradoxal and a gap that we need to fill, quickly” adds University of Yaoundé PhD student Suzanne K Mogue.

“We hope that our amazing discoveries continue to stimulate further botanical studies and promote conservation efforts across Cameroon, Gabon and central Africa in general,” concludes Professor Bonaventure Sonké of the University of Yaoundé.

Described 28 years post-collection, new grass species makes a strong case for conservation

Originally collected 28 years ago in Ecuador, new species Poa laegaardiana has been just described, only to find out its prospects for surviving in its type location seem bleak nowadays. The study was published in the open access journal PhytoKeys.

When roaming in the Cordillera de los Andes of Ecuador, near the village of Facundo Vela, little did Smithsonian scientist and author, Dr. Paul M. Peterson, know that a small grass specimen will not only turn out to be an intriguing new species, but will also make a big statement on the importance of conservation.

Scientific drawing showing what makes new species P. laegaardiana distinct from its congeners

Almost three decades after its original collection the new species P. laegaardiana has finally emerged from its herbarium collection, but the story took an unexpected twist.

It took the authors a single Google Earth search to find out that what used to be the natural habitat of the newly found densely tufted bunchgrass, is now occupied predominantly by small farms.

Heavy agricultural use of the terrain, poses a good possibility for P. laegaardiana to have already been extirpated from this location. With the species currently known only from this area, chances are that this newly described species, might in fact turn out to be already extinct.

“Further studies are needed to search the area and browse collections for specimens from different locations,” explains Dr. Peterson. “But, in fact, it may well be that with our study we are documenting a possible extinction of a species, happening in the space of just 30 years. The story of P. laegaardiana serves to show how human-induced habitat loss can indeed be a major threat to the survival of life on Earth.”

The new species was named after renowned Danish botanist Simon Laegaard, who has made extensive collections in South America, Greenland, Ecuador, and Bolivia (accompanied by the authors) contributing to the documentation of the flora to make informed conservation and management plans.

For PhytoKeys 100, we feature 5 amazing species that made the journal famous

Pensoft’s flagship botanical title PhytoKeys, celebrates its 100th issue and we couldn’t resist to look back on all the exciting plant species that made international media titles and touched audience hearts around the world.

With amazing 4 new species (find them in our press release) making it to the top 10 new species chart by the State University of New York College of Environmental Science’s International Institute for Species Exploration (IISE), PhytoKeys surely has a lot to offer when it comes to communicating plant science to the world.

So let’s go straight to facts with our celebratory selection of 5 famous species (among many others).

The Twitter-sourced Heuchera alba

While hunting for the Pennsylvania state-endangered golden corydalis on steep 350-foot cliffs for a new episode of his YouTube video series, “Plants are Cool, Too!” in the heat of summer 2017, Bucknell University Professor Chris Martine and team stumbled across some interesting specimens of the enigmatic coral-bell genus Heuchera. Posting an image of this find on Twitter, little did they know that one casual Tweet of a bumblebee on what he thought was Heuchera americana would not only stir a heated discussion among fellow botanists, but also lead to the unexpected-for-this-region record of the rare and globally imperiled Appalachian endemic Heuchera alba.

Telipogon diabolicus: orchid or demon?

A lone and unique population of about 30 reddish to dark violet-maroon orchids grows on the small patch of land between the borders of two Colombian departments. However, its extremely small habitat is far from the only striking thing about the new species. A closer look at its flowers’ heart reveals what appears to be a devil’s head. The new orchid was named Telipogon diabolicus after its demonic pattern.

Solanum ossicruentum: the bush tomato with bleeding fruit

A class of 150 US 7th graders has helped select a name for a newly discovered plant, which amazes with its fruits that appear to be bleeding once they are cut open. Based on this, the plant will now be known as Solanum ossicruentum, best translated to Australian as blood bone tomato, with “ossi” meaning “bone” and “cruentum” meaning “bloody”.

Luckily for Solanum ossicruentum, attention and protection are not too much of an issue. Find out why.

Sirdavidia solannona: the rare plant with a famous name

A new genus and species of flowering plant from the custard apple family, Annonaceae, has been discovered in the jungles of Gabon by French and Gabonese botanists. With its unusual flower structure characterised by red petals contrasting with its bright yellow loosely arranged stamens, the flowers of this newly discovered small tree did not quite fit any of the previously described genera. The extraordinary genus was named Sirdavidia, after Sir David Attenborough to honour his influence on the life and careers of the scientists who discovered it.
