Thinopyrum

3 species naturalised in Australia.

The taxonomy of the Triticeae (the tribe to which Thinopyrum belongs) is complicated and there is a wide range of circumscription and acceptance of genera within the tribe. Lophopyrum is sometimes treated as a separate genus, but Barkworth et al. (1983) and subsequent studies (e.g. Soreng et al. 2015) have shown that it is better placed within Thinopyrum.
