Summary
Anaphalis rosmarinifolia, a new species of Asteraceae, from the slopes of stream banks of montane grasslands of the southern Western Ghats of Kerala and Tamil Nadu, India, is described and illustrated. The new species exhibits morphological affinities with its allied taxon, Anaphalis marcescens, in its habit, leaf shape, heterogamous and disciform capitula and 16, uniseriate, free, barbellate pappus bristles. However, it differs in habitat preference, coriaceous leaf texture, glabrous adaxial leaf surface, acute recurved leaf apex, sheathed leaf base, number of rows of phyllaries, type and nature of receptacle, number of florets and glandular indumentum in cypselae. A description of the new species, along with details on distribution and ecology and an illustration, colour photographs and comparison with its allied taxa, using SEM data of cypselae, are provided.
Key Words: Anaphalis marcescens, endemism, Nilgiri Biosphere Reserve, stenoendemic.

Recognition. The new species is morphologically similar to Anaphalis marcescens (Wight) C.B.Clarke (Fig. 4) in overall habit, capitula type and the number, type and arrangement of pappus bristles. It differs from the latter by its habitat preference of wet rocks on the stream banks of montane grasslands (vs mud cliffs of montane grasslands in A. marcescens); coriaceous linear leaves (vs membranaceous linear); sheathing leaf base (vs decurrent); glabrous adaxial leaf surface (vs sparsely arachnoid midrib); leaf apex
Etymology. The specific epithet is based on the similarity of its leaves with those of rosemary (Salvia rosmarinus Spenn.), a medicinal and culinary plant in the Lamiaceae.
