''Eragrostis'' is a large and taxonomically complex genus comprising more than 350 species mainly in tropical and subtropical regions. ''Eragrostis annulata'' resembles the forage species ''Eragrostis cilianensis'' (All.) F.T.Hubb., but the latter lacks gland-tipped hairs and has a globose grain.
In its native region ''Eragrostis annulata'' flowers from February to May.
== Ecology ==
''Eragrostis annulata'' is found on a range of soil types, especially on sandy, stony or calcareous soils where the groundwater table is high, and in disturbed locations.
