The newly-described species Didymocarpus vickifunkiae (Gesneriaceae) is currently known from only three locations in Mizoram and considered as an endangered species. It is an epiphyte (plants that grow on trees) and produces light pink flowers during the monsoons. The species is named in honour of late Dr. Vicki Ann Funk, a renowned Botanist who worked at Smithsonian Institute, USA.

Along with other discoveries by the IISER Bhopal Research Team in the past few years, this recent discovery shows that the rich biodiversity of the northeastern parts of India remains unexplored and there are many species of plants that remain undiscovered.
“This discovery is an outcome of extensive fieldwork across northeast India coupled with rigorous study of past collections kept in herbariums across the world,” said an IISER spokesperson.
The discovery has been published in the reputed journal Systematic Botany (a peer reviewed journal published by American Society for Plant Taxonomists) in a paper co-authored by Prasanna NS, research scholar, and Dr Vinita Gowda, associate professor at department of biological sciences in IISER Bhopal.
“Northeast India is home to highly diverse flora because of its unique biogeographic placement as part of two biodiversity hotspots: the Indo-Burma hotspot and the Eastern Himalayas,” Dr Vinita Gowda said.
“This is science in its finest form – a field of investigation that seeks knowledge and depth because, for man, there is much to learn in the wonders of nature,” Dr Gowda added.
According to the researchers the new discovery brings new insights into the unique evolutionary trajectory of flora in India’s northeast, know for its biodiversity. Beyond the academic desire to document biodiversity, finding the ‘missing pieces’ of the biodiversity puzzle are important in designing conservation approaches to protect the fragile ecosystem of such hotspots, a researcher said.
Didymocarpus is a genus belonging to the plant family Gesneriaceae (commonly known as ‘African Violets’) and its members are distributed from Western Himalayas to Sumatra. Most of these species are narrow endemics and require specialized habitats to survive, thus acting as an indicator of pristine habitats. There are 106 currently known species of this genus, of which 26 are present in northeastern states of India, the research team informed.
Because of its complex geology and climatic conditions, northeast India, is home to a diverse flora and fauna. However, much of it remains poorly documented, even as the IISER Bhopal team was studying the evolution and biogeography of Didymocarpus plants.
While collecting the plants for study, authors stumbled upon a plant which was distinct from all botanically known plants. After critical examination of the morphology, published literature and past collections that are preserved in the natural history museums in India and UK, they described it as a new species.
“The biodiversity in this region of the country is poorly known due to low priority in research, inaccessibility and remoteness, challenges that are being tackled by research groups such as the TrEE lab,” read a statement by the Institute.
The team combines traditional processes of taxonomy with modern methods such as molecular phylogenetics to unravel the biodiversity of the northeast and place it in the context of the larger Asian landscape.
