A new species of Mussaenda (Rubiaceae) from the southern extent of the Western Ghats Mountain Range, India

Mussaenda conferta, a new monomorphic species from the southern extent of India's Western Ghats Mountain range, is described and illustrated. The new species is morphologically similar to Mussaenda hirsutissima but distinct by its growth form, shape and size of the stipules, calycophylls and fruits. SEM images of the pollen and seeds of the new species are provided here showing (3-)4-colporate grains and the seeds with tubercular thickenings in inner periclinal and anticlinal walls.
