It happens dont worry :p

This is Ischaemum semisagittatum. The bicolor nature is just an abnormality. This can be because of various reasons, the main reason being just a genetic segregation. Some physiological disorder causing improper partitioning of Magnesium (which is the main component of chlorophyll) can also cause this symmetrical discolouration. Effect of certain chemicals in soil, herbicide drift, etc. can also cause this. Usually, such variations are temporary and are not inherited. However, there are several cultivated varieties of ornamental grasses which show variegated leaves.

‎Ischaemum species so far in efi

Yes, it is Ischaemum, most probably Ischaemum semisagittatum, a common grass found in northern part of western ghats and Konkan coast. You can find this grass on all the railway station platforms of Konkan railway. The variably hairy spikelets and the semi-sagittate leaf base leads to the identity of this species. The picture on the left reveals the leaf base on some of the leaves in which the base is clear in the picture. The leaf bases are pointed on both sides of the petiole like an arrow. You may have to scan thoroughly to see this feature!

Poaceae, Grass: Ischaemum dalzellii Staph ex Bor – for confirmation : 5 posts by 2 authors. Attachments (4)

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.
