Agropyron

It is now agreed that Agropyron should be restricted to A. cristatum and its close relatives, i.e., the crested wheatgrasses. There is less agreement on how its members should be treated. The genus is native to Eurasia. The table below is based on Tsvelev's (1976) treatment, with additional information being taken from Yang (1987) and other sources. The listing is alphabetical.
