Ischaemum‎‎ (Poaceae) page with comparative images:
Pl. go through‎ Ischaemum‎‎ (Poaceae) page with comparative images of species in efloraofindia. On clicking the link of species, one can check the complete details.
I request you to pl. go through & point out mistakes, if any. I hope this will aid in identification in future. If anybody can send images of other species of this genus (for incorporation in the website), if any, or can identify unidentified images, it will be really nice. Pl. circulate it widely, for the benefit of all concerned.
Thanks a lot, Manoj Chandran ji, for most of the identifications.
