Abstract

Geum macrosepalum Ludlow (Rosaceae), hitherto known only from Luguthang of Arunachal Pradesh and Hewalungi of Sikkim in India, has been rediscovered after at least a lapse of 120 years from the Se La area between the Tawang and West Kameng districts. Comments on its conservation status and distribution range are provided, together with a distribution map where the threat status has been assessed as ‘Vulnerable.’ Field photographs of the species with dissected flowering parts and a taxonomic key from India have also been provided for its easy identification. This rediscovery highlights the importance of further fieldwork in highly biodiverse alpine regions of Arunachal Pradesh as well as emphasizes the urgent requirement for conservation of the highly threatened eastern Himalayan flora.
