Abstract
Memecylon coorgensis sp. nov., a small shrubby species from the Kodagu district of Karnataka, India, is described and illustrated. The species is similar to Memecylon gracile with respect to its axillary, peduncled inflorescence but differs in having up to six flowers per inflorescence, in addition to the conical shape of its buds, its acute sepals and its acuminate petals. The species is so far known only from the Kodagu district of the state of Karnataka.

Memecylon coorgensis is morphologically most closely related to M. gracile with respect to its small shrubby habit, long acuminate leaf apex, and long-peduncled axillary inflorescence. Memecylon coorgensis differs from M. gracile in having up to 2 peduncles in the leaf axils (vs solitary peduncles), up to 5 secondary peduncles (vs secondary peduncles either absent or if present only 1 in number), 1–6(–8) flowers per inflorescence (vs 1–3 flowers per inflorescence), calyx deeply lobed with sepals acute or acuminate at apex (vs calyx shallowly lobed with sepals triangular-obtuse at apex), acuminate petals (vs petals obtuse), and berry 8–11 mm in diameter (vs berry 6 mm in diameter).
