This is Ischaemum semisagittatum
Comment Please: Came across bicolour leaves of grass, Expert may
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.

Requesting to please provide ID of this grass captured near Satara, Maharashtra in October 2014.
Belongs to Ischaemum sp.
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!

Requesting to please ID this grass captured at Kanheri Caves, SGNP in Sep 2014.
Seems to be an Ischaemum sp.
There are two species of Ischaemum in these photos. The inflorescences in 5554 (two racemes are yet to separate) and 5557 (both racemes separated wide apart) are of Ischaemum indicum, whereas the leaves seen in 5553 are of Ischaemum semisagittatum, where the leaf base is seen sagittate.
Images contain 2 sp. of Ischaemum
1. Ischaemum semisagittatum which shows sagitate lvs in first image
2. Ischaemum indicum shich shows acute leaf base

Poaceae, Grass: Ischaemum dalzellii Staph ex Bor – for confirmation : 5 posts by 2 authors. Attachments (4)
On a shady, narrow track leading to a (mini) fort @ Roha, 08-11-2015.
height: 30-50- cms
Also considered I. commutatum.
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:
