摘要
Hoya nagaensis (Apocynaceae, Asclepiadoideae), a new species from the state of Nagaland, India is here described and illustrated. The new species has close morphological affinity with H. thomsonii and H. coronaria. It can be clearly distinguished by its densely hairy corolla lobes, both internally and externally; irregular pinkish to reddish-purple spots on the external corolla surface and, though less pronounced, on the inner surface and narrowly elliptic-lanceolate leaves, with smooth surfaces and long acuminate tips. A detailed morphological description, habitat information, preliminary conservation assessment, notes and comparison with closely related species, H. coronaria, H. carnosa, H. spectatissima, H. bella and H. thomsonii are provided.
