Studies On The Endemic Liparis (Orchidaceae) In North-East India And Red List Assessment As Per IUCN Criteria

Abstract

Taxonomic studies on the genus Liparis Rich. (Orchidaceae) has been conducted in North-East India. Out of 32 taxa reported under this genus from North-East India, four species viz. Liparis chungthangensis Lucksom, Liparis lydiae Lucksom, Liparis pygmaea King & Pantl., and Liparis torta Hook.f. are endemic to India. These endemic species were studied for their taxonomy and threat status were assessed by following the IUCN guidelines. While L. chungthangensis and L. lydiae were assessed as Critically Endangered, L. pygmaea and L. torta were found as Endangered in global perspective. Detailed morphology, phenology, distribution and rationale for their red list assessments have been provided here.
