摘要

The nomenclatural confusion between the Indian gingers Hedychium villosum Wallich and its variety Hedychium villosum var. tenuiflorum (Wall. ex Voigt) Wall. ex Baker is discussed. Both taxa are lectotypified in order to stabilize the names and contribute towards a resolution of their confusing nomenclatural past. Both taxa are described in detail to aid identification.
