Cymbidium whiteae King & Pantl is an endemic and endangered orchid species found in Sikkim, India. We evaluated the current population distribution and conservation needs of this species during 2017–2019 in North Sikkim, Sikkim, India. The distribution of the species ranged from 1020 to 1479 m a.s.l. but was confined to a small restricted area of the lower Dzongu region of North Sikkim district. The numbers of clumps at survey sites varied from 2 to 5 with a total population of 43 clumps at 17 sites. The flower number and capsules per clump varied from 4 to 12 and 3 to 12, respectively. Some flowering‐sized individuals neither flowered nor set any seed pods. Preliminary studies on asymbiotic seed germination indicated that seeds germinate on MS media supplemented with 0.2 mg BAP and develop into plantlets on the same media. We analysed the distribution pattern, prepared a distribution map, assessed the conservation status based on the IUCN criteria, and suggest suitable in situ and ex situ conservation measures and sustainable utilization. Based on the IUCN criteria, Cymbidium whiteae was assessed as critically endangered (CR).

some extent with Burmese-Thailand elements. Andaman and Nicobar Islands are known to harbor 2650 species (Pandey & Diwakar 2008), of which 308 taxa are classified as strict endemics. Orchidaceae is one of the largest family of the flowering plants comprising about 22,075 species (APG III, 2009) and almost cosmopolitan in distribution, except in Antarctica. Most of the orchids are native to tropical countries and occur in their greatest diversity in humid tropical forests. The family is represented in India by 1331 taxa (Misra 2007), of which about 151 species are found in Andaman and Nicobar Islands (Rao et al. 2012).While working on DBT sponsored project on 'Quantitative Assessment and Mapping of Plant Resources of the Andaman and Nicobar Islands', the authors could collect some curious orchid specimens from Middle Andaman Islands. After critical examination they were identified as Saccolabiopsis pusilla (Lindl.
