The Genus Eragrostis (Poaceae: Chloridoideae) in India: Taxonomic Revision


The taxonomic revision of the genus Eragrostis Wolf in India recognizes 42 species and 5 varieties. Eragrostis tenella var. peramangalamensis is synonymised under Eragrostis tenella var. tenella. Eragrostis burmanica is reported as an addition to India from the state of Manipur. The morphology, taxonomy, nomenclatural/bibliographic citations, phenology, distribution and ecology of every taxon are discussed along with descriptions, illustrations and key to all the species and varieties.
