This paper presents a taxonomic revision based on morphology of the genus Eriachne R. Br. which includes 51 taxa (48 species, two varieties and one subspecies), of which 10 species are presented as new. Changes in nomenclature include three new combinations. Five species and 13 varieties are reduced to synonymy, and two trinomials are placed in synonymy. Lectotypes are designated for four taxa. The distributions of E. humilis and E. obtusa are extended to Irian Barat, the former also to Papua New Guinea, and E. armitii and E. nervosa to Western Australia. Cleistogamy and a vesicular indumentum are noteworthy features.
