Two Rare Orchids, One Vanishing Forest: Ecuador’s Newest Dracula Species

The genus Dracula is one of the more theatrical corners of the orchid world, containing more than 130 species.

A new species of vampire orchid, described in the open-access journal PhytoKeys, was recently discovered in the cloud forests of southwestern Ecuador, and with it comes the long-awaited confirmation of where a second, mysterious species actually lives in the wild.

The genus Dracula is one of the more theatrical corners of the orchid world. It contains more than 130 species, most found in the northern Andes of Colombia and Ecuador, and is known for its dramatic and often dark-coloured flowers with long tails. These blooms are pollinated by small flies rather than by bees or butterflies, that mistake the flower’s lip for a mushroom!

The newly described species, Dracula aguilarii, was found in El Oro Province, in a region of premontane and cloud forest that sits between 900 and 1,200 metres above sea level. Its cream-coloured flowers are suffused with brown-red tones and covered in short, dense hairs. It closely resembles a related species, D. hirtzii, but can be told apart by its blunt-tipped leaves, a deep and broadly rounded cup formed by the fused sepals, and notably shorter tails on those sepals.

The species owes its name to Mario Aguilar, a farmer and orchid enthusiast from El Oro with a remarkable knack for spotting rare orchids in the field. It was Aguilar who first came across a small population of around fifteen plants in a patch of remnant forest near the town of Balsas, more than a decade ago. Researchers later confirmed, through further fieldwork and herbarium comparisons, that his discovery represented a species new to science, and named it in his honour.

Only three populations of Dracula aguilarii are currently known, all within a fairly small area, which has led researchers to recommend the species be classified as Endangered. The forests it depends on are being steadily cleared for cattle pasture, and like many showy orchids, it also faces pressure from illegal collection for the horticultural trade.

Jiménez from a cultivated plant collected near Balsas.

This same study resolves a smaller mystery that has lingered for well over a decade. Dracula soennemarkii was first described in 2012 from a plant bought at a nursery and grown in Sweden, with no idea of where it had originally come from in the wild. The researchers have now traced a wild population of this species to the same general region of El Oro, giving it a confirmed home for the first time. Given that it is known from just a single location, D. soennemarkii has been assessed as Critically Endangered, an even more precarious position than its newly described neighbour.

Together, these findings demonstrate just how much remains to be discovered, and how quickly it could be lost, in Ecuador’s shrinking cloud forests. El Oro Province alone now hosts six recognised species of Dracula, yet only a fraction of its once-extensive humid forest cover remains intact. Each new species description is as much a conservation appeal as it is a taxonomic milestone.

The most beautiful Vanilla: an unusual new species from Brazil’s Campos Rupestre

Brazilian Campos Rupestres have many endemic species, and a new study published in the journal PhytoKeys has just added one more.

One of the most beautiful vanilla orchid species in the Neotropical region grows in one of the most hostile environments in the Brazilian Cerrado, the Brazilian Campos Rupestres of the Espinhaço Range. “The Espinhaço refuges evolved between the Atlantic Forest and Amazonia Biomes as a consequence of extreme environmental conditions and climatic fluctuations during the Tertiary and Quaternary periods,” explains Emerson Ricardo Pansarin, one of the researchers behind the discovery of a new vanilla orchid.

Brazilian Campos Rupestres have many endemic species, and a new study published in the journal PhytoKeys has just added one more.

What makes Vanilla rupicola remarkable is the fact that it grows on rock outcrops. “In this locality, Vanilla rupicola shows a reptant habit on rock outcrops and rooting in rock clefts. The elevation is from 800 to 1300 m a.s.l.,” the researchers write in their paper. Its flowers produce a sweet fragrance that can be noticed during the hottest hours of the day.

“For years we traveled through the mountains of the Espinhaço Range until we found the flowering population,” says Emerson Ricardo Pansarin.

“Vanilla rupicola emerges in an essentially Amazonian clade. It seems plausible that the ancestor of this new taxon derived from an Amazonian taxon adapted to the environmental conditions of the Espinhaço Range and evolved in this particular environment,” he adds.

Vanilla rupicola is a rare species currently known to grow in a mountain-chain of Diamantina, in the ERMG Espinhaço Range, and the researchers tentatively classify it as Endangered.

Endangered new orchid discovered in Ecuador

The plant – unique with its showy, intense yellow flowers – was described by Polish orchidologists in collaboration with an Ecuadorian company operating in orchid research, cultivation and supply.

An astounding new species of orchid has been discovered in the cloud rainforest of Northern Ecuador. Scientifically named Maxillaria anacatalina-portillae, the plant – unique with its showy, intense yellow flowers – was described by Polish orchidologists in collaboration with an Ecuadorian company operating in orchid research, cultivation and supply.

Known from a restricted area in the province of Carchi, the orchid is presumed to be a critically endangered species, as its rare populations already experience the ill-effects of climate change and human activity. The discovery was aided by a local commercial nursery, which was already cultivating these orchids. The study is published in the open-access journal PhytoKeys.

During the past few years, scientists from the University of Gdańsk (Poland) have been working intensely on the classification and species delimitations within the Neotropical genus Maxillaria – one of the biggest in the orchid family. They have investigated materials deposited in most of the world’s herbarium collections across Europe and the Americas, and conducted several field trips in South America in the search of the astonishing plants.

The first specimens of what was to become known as the new to science Maxillaria anacatalina-portillae were collected by Alex Portilla, photographer and sales manager at Ecuagenera, an Ecuadorian company dedicated to orchid research, cultivation and supply, on 11th November 2003 in Maldonado, Carchi Province (northern Ecuador). There, he photographed the orchid in its natural habitat and then brought it to the greenhouses of his company for cultivation. Later, its offspring was offered at the commercial market under the name of a different species of the same genus: Maxillaria sanderiana ‘xanthina’ (‘xanthina’ in Latin means ‘yellow’ or ‘red-yellow’).

In the meantime, Prof. Dariusz L. Szlachetko and Dr. Monika M. Lipińska would encounter the same intriguing plants with uniquely colored flowers on several different occasions. Suspecting that they may be facing an undescribed taxon, they joined efforts with Dr. Natalia Olędrzyńska and Aidar A. Sumbembayev, to conduct additional morphological and phylogenetic analyses, using samples from both commercial and hobby growers, as well as crucial plants purchased from Ecuagenera that were later cultivated in the greenhouses of the University of Gdańsk.

As their study confirmed that the orchid was indeed a previously unknown species, the scientists honored the original discoverer of the astonishing plant by naming it after his daughter: Ana Catalina Portilla Schröder.

Rare, protected orchid thrives in a military base in Corsica

Counting over 155,000 individuals, the population is a world precedent. Globally, this orchid can only be found in the south of France, Italy, and along the east coast of the Adriatic.

In Corsica, away from the eyes of locals and tourists, hides a population of unprecedented proportions of a rare and protected orchid: the neglected Serapias (Serapiasneglecta). In a closed military base in the east of the island, researchers discovered 155,000 individuals of the plant.

Globally, this orchid can only be found in the south of France (including Corsica), Italy, and along the east coast of the Adriatic, but none of its known populations has been as abundant as the one documented in Solenzara.

Margaux Julien, Dr Bertrand Schatz, Simon Contant, and Gérard Filippi, researchers from the Center of Functional Ecology and Evolution (CEFE) and Ecotonia consultancy,came across this population while studying plant diversity in the Solenzara air base. Their research, published in Biodiversity Data Journal, documented impressive plant richness, including 12 other orchid species.

The maintenance of the closed military area turned out to be really favourable to the development of orchids. The flower was abundant around the edges of runways and on lawns near military buildings.

“Мilitary bases are important areas for biodiversity because they are closed to the public, are not heavily impacted and these areas have soils that are often poorly fertilised and untreated due to old installations, so they often have high biodiversity,” the researchers say in their study.

The meadows around the airport are regularly mowed for security reasons, which allows orchids to thrive in a low vegetation environment with little competition. In addition, the history of the land with its position on the old Travo river bed favours low vegetation, providing rocky ground just a few centimetres beneath the soil.

“The case of S. neglecta is particularly remarkable, because this species benefits from a national protection status and it is a sub-endemic species with a very localised distribution worldwide,” the research team writes. Moreover, the species is classified as near threatened in the World and European Red Lists of the International Union for Conservation of Nature.

The Ecotonia consultancy also did several inventories on the air base, finding biodiversity of rare richness: 552 species of plants, including 19 with protected status in France. Within only 550 ha, they found 23% of the plant species distributed in Corsica. Among these are some very rare plants, as well as endangered species such as the gratiole (Gratiola officinalis) and Anthemis arvensis subsp. incrassate, a subspecies of the corn chamomile.

The Solenzara military base hides rich floristic diversity thanks to its history, management, and the lack of public access. While the Corsican coastline is suffering from urbanisation, this sector is a testament to the local flora, featuring several species with conservation status.

The protection of this richness is crucial. “If logistical developments are carried out on this base, they will have to favour the conservation of this exceptional floristic biodiversity, and, in particular of this particularly abundant orchid. Military bases are a great opportunity for the conservation of species and would benefit from enhancing their natural heritage,” the researchers conclude.

Plants cheat too: A new species of fungus-parasitizing orchid

Plants usually produce their own nutrients by using sun energy, but not all of them. A new ‘cheater’ species of orchid from Japan, lives off nutrients obtained via a special kind of symbiosis with fungi. The study was published in the open access journal PhytoKeys.

The new orchid species, named Lecanorchis tabugawaensis, is by far not on its own in its strange feeding habits. The so called mycoheterotrophic plants are found among all plant species groups.

Mycoheterotrophy is a term derived from Greek to describe the bizarre symbiotic relationship between some plants and fungi, where the plant gets nutrients parasitizing upon fungi, rather than using photosynthesis.

Considered a kind of a cheating relationship, these plants are sometimes informally referred to as “mycorrhizal cheaters”.

Having long attracted the curiosity of botanists and mycologists, a common feature of most mycoheterotrophic plants is their extreme scarcity and small size. In addition, most species are hiding in the dark understory of forests, only discoverable during the flowering and fruiting period when aboveground organs appear through the leaf litter.

Despite it seems like these ‘cheating’ plants have it all easy for themselves, in reality they are highly dependent on the activities of both the fungi and the trees that sustain them. Such a strong dependency makes this fascinating plant group particularly sensitive to environmental destruction.

“Due to the sensitivity of mycoheterotrophic plants it has long been suggested that their species richness provides a useful indicator of the overall floral diversity of forest habitats. A detailed record of the distribution of these vulnerable plants therefore provides crucial data for the conservation of primary forests,” explains leading author Dr Kenji Suetsugu, Kobe University.

Just discovered, the new orchid species has been already assessed with an IUCN status – Critically Endangered. With a distribution restricted to only two locations along the Tabu and Onna Rivers, Yakushima Island, this fungus-eating cheater might need some conservation attention.

Orchid or Demon: Flower of a new species of orchid looks like a devil’s head

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. Named after its demonic patterns, the new orchid species, Telipogon diabolicus, is described in the open access journal PhytoKeys.

Discovered by Dr Marta Kolanowska and Prof Dariusz Szlachetko, both affiliated with University of Gdansk, Poland, together with Dr Ramiro Medina Trejo, Colombia, the new orchid grows a stem measuring between 5.5 – 9 cm in height.

With its only known habitat restricted to a single population spread across a dwarf montane forest at the border between departments Putumayo and Nariño, southern Colombia, the devilish orchid is assigned as a Critically Endangered species in the IUCN Red List.

Although the curious orchid could be mistakenly taken for a few other species, there are still some easy to see physical traits that make the flower stand out. Apart from the demon’s head hidden at the heart of its colours, the petals themselves are characteristically clawed. This feature has not been found in any other Colombian species of the genus.

“In the most recent catalogue of Colombian plants almost 3600 orchid species representing nearly 250 genera are included,” remind the authors. “However, there is no doubt that hundreds of species occurring in this country remain undiscovered. Only in 2015 over 20 novelties were published based on material collected in Colombia.”

Serendipitous orchid: An unexpected species discovered in Mexican deciduous forests

A new elegant orchid species that grows on rocks in deciduous forests of the Pacific slope of Oaxaca state, Mexico, has finally put an end to a long standing dispute among taxonomists. ‘Sheltered’ under the name of a close relative, the plant has been proved by a research team, led by Dr. Leopardi-Verde, to be different enough for a species of its own. Its distinct features, including shape, size and colors, are discussed and published in the open-access journal PhytoKeys.

When scientists Drs. Carlos L. Leopardi-Verde, Universidad de Colima and Centro de Investigacion Cientifica de Yucatan, German Carnevali and Gustavo A. Romero-Gonzalez, both affiliated with Centro de Investigacion Cientifica de Yucatan and Harvard University Herbaria, stumbled across a beautiful orchid in bloom, they found themselves so surprised by its unique colors and forms that later on they chose the specific epithet inopinatus, meaning “unexpected”.

One of the most distinctive characters of the new plant is the yellow labellum patterned with crimson to reddish brown lines. Typically for its species complex, this orchid’s leaves are wide and leatherlike and the flowers are relatively large, showy, and leathery to fleshy-leathery petals and sepals. The color of the flowers varies from bronze-green with dark purple lines near the base to pale pink and creamy white splashed with reddish-brown spots and lines towards the top.

The plant is between 30 and 42 cm tall, while together with its flowers it reaches between 80 and 90 cm. Each branch of the inflorescence bears from 3 to 8 flowers, which bloom between March and July. Having been recorded only from a few sites on the Pacific slope of Oaxaca state, Mexico, the species appears to be rare.

The authors explain the similarities between the new species and its close relatives. They also discuss the long-held confusion about its taxonomic placement. As a result of the study, a hypothesis about hybridization that has played a role in the evolution and origin of the novelty has been refuted.
