- Abstract
An extremely rare, long-lost, monotypic endemic, Indian liverwort, Sewardiella tuberifera Kash. has recently been recollected after a gap of over three-and-a-half decades from an altogether new location, the Mukteshwar region (2,171 m) of Nainital district in the Kumaun Himalaya, Uttarakhand. The remarkable rediscovery of this monotypic, endemic Himalayan liverwort is a significant finding for the world's bryological treasure. Along with other rare Himalayan monotypic endemics such as Aitchisoniella himalayensis Kash. and Stephensoniella brevipedunculata Kash., the currently located sporiferous population of Sewardiella was discovered persisting in small, dispersed, sparse patches with 5-30 individuals. The currently spotted collection site is being considered a 'bryological hotspot'. As the area develops as a popular ecotourism destination, the original habitat of these hepatics in a lime stone-dominated, south-west facing, unstable sloppy site at Mukteshwar is under constant pressure from several developmental activities. Hence, serious conservation steps are needed to protect this hotspot supporting Himalayan bryophyte jewels. To ensure long term perpetuation and conservation of redlisted hepatic taxa, an attempt is being made to translocate part of the population to ecologically and climatically identical safer site, including a developing 'moss garden' at Lingadhar (Nainital).
