This is Eragrostis stenophylla of the Fl. of British India. However, this is a taxonomically controversial species. The species is often referred as E.gangetica at many places, but E.gangetica is an annual species, whereas this one is a perennial species found in moist localities (It is very difficult to uproot this species by hand due to its strong below ground parts). Another species which is very similar is E.atrovirens, but it does not have glandular patches. This picture shows several glandular patches. Though E.stenophylla has been considered by many authors to be synonymous with E.gangetica, E.atrovirens, E.nutans, etc., it is safe to preserve the name E.stenophylla.
