Impatiens roingensis from Arunachal Pradesh, northeast India, is described as new. A detailed description of the plants, their distribution and ecology along with colour photographs are provided for ease of identification.
Osbeckia saddlepeakensis, a new species of Melastomataceae from Andaman and Nicobar Islands, India is described. The new species is easily distinguished by its small flowers, hypanthium with emergences only on basal portion, lanceolate and ciliate sepals, short stalked intersepalar emergences and oblong to narrowly ovoid anthers with a single apical pore.
Didymocarpus moellerii, a new species from northeastern India is described and illustrated with photographs. Information on its ecology is provided as well. The new species is morphologically similar to D. glandulosus and D. tonghaiensis but can be easily distinguished by a combination of characters such as glabrous peduncle, orbicular purple bracts, puberulent anthers, orange-red corolla with white stripes at the throat, longer ovary, bulged ovary apex and cup-like disc.
The genus Osbeckia L. comprises about 50 species worldwide, is principally Asiatic in distribution. The genus is represented by 23 species and 4 varieties under four sections in India. The main centers of endemism are in Eastern Himalayas and the Western Ghats. A taxonomic treatment of Osbeckia in India is presented here with morphological descriptions, geographic distribution, notes, photo plates and identification key for sections, species and infra-specific taxa. Seven names are lectotypified and eight names are synonymised.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
