Recent botanical expeditions in Caquetá department (southeastern Colombia) have uncovered the enormous richness of plant species in this region. Research led by W. Trujillo in the Andean foothills has allowed the unveiling of at least 90 species of Piper in the region, highlighting northwestern Amazonia as one of the richest regions for the genus. Here, four new species of Piper new to science are described.
This publication is the result of a collaboration between three institutions and five researchers, each contributing their experience and strengths: main author William Trujillo (Fundación La Palmita), with M. Alejandra Jaramillo (Universidad Militar Nueva Granada), Edwin Trujillo Trujillo, Fausto Ortiz and Diego Toro (Centro de Investigaciones Amazónicas Cesar Augusto Estrada Gonzalez, Universidad de la Amazonia). W. Trujillo, a native of Caquetá, has dedicated the last ten years to the study of Piper species in his department. M. A. Jaramillo has been studying the phylogenetics, ecology and evolution of the genus for more than 20 years. Edwin Trujillo is a local botanist well versed in the flora of Caquetá and the Colombian Amazon. Fausto Ortiz and Diego Toro are trained in plant molecular biology methods and lead this area at Universidad de la Amazonia.
Caquetá is situated where the Andes and the Amazon meet in southern Colombia, in the northwestern Amazon. Several researchers have highlighted the importance of the northwest Amazon for high biodiversity and our lack of knowledge of the region. Fortunately, ongoing studies led by W. Trujillo and E. Trujillo are unveiling the immense diversity of plants in Caquetá, showing the importance of local institutions in the knowledge of Amazonian flora. There are many species in the region yet to be described and discovered. Leadership from local institutions and collaboration with experts are vital to appreciating the great relevance of plants from Caquetá.
Two of the species in this manuscript (Piper indiwasii and Piper nokaidoyitau) bear names inspired by the indigenous tribes that live in Caquetá. The name indiwasii comes from a Quechua word meaning “house of the sun” and is also the name of one of the National Parks where the species lives in southern Colombia. In its turn, nokaidoyitau comes from the Murui language and means “tongue of the toucan,” the way the Murui Indians of the Colombian Amazon call the species of Piper. In fact, local communities rely on these plants for medicinal purposes, using them against inflammations or parasites, or to relieve various ailments.
Furthermore, the other two new species (Piper hoyoscardozii and Piper velae) honor two Amazonian naturalists, the authors’ dear friend Fernando Hoyos Cardozo, and Dr. Vela. Fernando, who was a devoted botanist and companion in W. Trujillo’s botanical expeditions. Dr. Vela, a naturalist and conservation enthusiast who sponsored Trujillo’s trips, was killed in 2020. We miss him immensely. His death is a significant loss for the environment in Caquetá.
The team’s joint effort will continue to describe new species, explore unexplored regions, and inspire new and seasoned researchers to dive into the magnificent diversity of the Colombian Amazon.
