Abstract

Nomenclatural notes on the species of Dioscorea L. described by J.D. Hooker in the Flora of British India are presented here. The study is based on the critical evaluation of all available original materials from various herbaria (BM, E, G, K, L, P and CAL). Lectotypes for seven names, viz. D. collettii Hook.f., D. gibbiflora Hook.f., D. jacquemontii Hook.f., D. laurifolia Wall. ex Hook.f., D. obcuneata Hook.f., D. polyclades Hook.f. and D. wightii  Hook.f. are designated here.
