This is Isachne globosa. Look carefully and you can see the glandular band on the pedicels of the spikelets, which is characteristic of only a few of the species of the genera and only this species from peninsular india has this character

Family – Poaceae
Habitat – Found along brooklets in marshy paddy fields sharing habitat often with Ischaemum polystachyum.
I was earlier thinking this grass to be Isachne globosa which is widely distributed species but because of its erect habitat with large globose purple spikelets, narrower leaf blades and presence in Himalayan region, i think this is Isachne himalaica.
Experts please validate…
Photographed at Hamirpur, Himachal Pradesh
Altitude – 700metres asl.
Isachne globosa. You can see the glands on the pedicels of the spikelets, which is a characteristic feature of I.globosa. Isachne himalaica has a denser panicle with more branches and linear-lanceolate shape of panicle.
You also mentioned that it shares habitat with Ischaemum polystachyum. But the other grasses in the picture seems to be some other species. Could you kindly send pictures of inflorescence of this grass too to validate its identity.
Thanks a lot … for correcting and clearing differences.
The grass sharing habitat with Isachne globosa is Ischaemum polystachyum, which was also earlier identified by you.
Here i am sharing its link, you can see Isachne growing with it in one of the image…

Place, Altitude: Tungareshwar Wildlife Sanctuary … about 270 ft asl
Date, Time: 09 OCT 10 … 09:11am
Habitat: along path in forest
Habit: small herb; about 1 ft high
Only these views, with no adequate information of other aspects may not help in ID.
Cyrtococcum accrescence. The spikelets should be plano-convex.
If it is semi-aquatic habitat, it could also be Isachne sp. Cyrtococcum is usually found in dense shade in forest areas, whereas Isachne is a plant of semi-aquatic habitats.
Many thanks … for the clarification.
This sighting is along a forest path; the soil however is almost perennially moist, species like Ludwigia and other mat forming low herbs grow around this place, indicating presence of water underground.
I would go with the tentative ID of Isachne sp.
Isachne globosa Kuntze ??
I am convinced with your ID, … Many many thanks.
I hope we have someone seconds your thought.
I have revised my notes at flickr accordingly.
Yes, Isachne globosa
