Abstract
Endopogon versicolor Wight, previously treated as a synonym of Strobilanthes cuspidata (Benth.) T. Anderson, is reinstated as a distinct species and a new name S. benthamii B. Mani, Sinj. Thomas, Britto, A.K. Pradeep, Y.F. Deng & E.S.S. Kumar is necessarily proposed here. It differs from S. cuspidata by the stem and leaf indumentum, bract/calyx length ratio, corolla shape, pollen morphology, etc. Detailed descriptions, illustrations, pollen morphology and comparison with similar species are provided.

Horizon e-Publishing Group proposed by Bremekamp and a single broad circumscription for Strobilanthes has been accepted [5,6,7]
