This is again Ischaemum semisagitattum, but with pilose spikelets, recognised as var.dasyanthum by Hackel. But I do not consider it as a variety as the glabrous and pilose nature of spikelets are found in varied forms even in the same population. I.dalzellii has been separated from I.semisagittatum as a different species Stapf and explained by Bor in 1951.

The lower leaves of Ischaemum dalzellii have long petioles along with hastate leaf bases, but I don't think has been collected for a long time. Whether such a species exist is also a question. It could be a variation of I.semisagittatum itself, but more collections are required to check the same. The type of I.dalzellii at Kew was collected by Talbot from Yellapur in North Karnataka in 1885. It can be seen from the following site:

I have also come across another collection of I.dalzellii from Dandeli collected by Udaya Kumar and Gurudev Singh in 1982 and deposited in Indian Institute of Science herbarium and can be seen from the following site:
