. It is primarily Australasian in its distribution, having five species native to New Zealand, 4 to Australia, and 1 to New Guinea. The Australian species are confined to the southern half of the continent.
Members of ''Anthosachne'' are non-rhizomatous, perennial grasses with spikelike inflorescences having one spikelet per node. They tend to differ from North American and Eurasian species of ''Elymus'' in having more slender stems, longer, usually curved awns, and glumes that are shorter in relation to the lemmas. They also differ in being hexaploids that combine the St, Y, and W genomes whereas ''Elymus'' consists of tetraploids and hexaploids that combine the St and H genomes. . The W genome is found only in Australasia, occurring also in the diploid genus ''Australopyrum.''
