Thanks Dinesh ji and Shrikant ji I had to put this question because while resurfacing the photographs of another species (identified as E. purpurascence), the doubts arose in mind. Perhaps soon we would resurface all these together, and my plant from Delhi which I knew as E. nervosum (now correctly E. pulchellum) which needs to be checked for both E. roseum and E. pulchellum, apparently close species which can be confused. As suggested by Shrikant ji the differences are largely based on spike size and bracts shape. Let us concentrate on that for both Delhi plant and those from Western Ghats.
