Aegilops L. 1753 - (goatgrasses)
The genus is native to Europe and Asia but several species have spread to other regions. The weedy species are mainly a problem in wheat and several wheat pest and diseases (e.g. the Russian wheat aphid) also colonize Aegilops species. In fact cultivated wheat is closely related to Aegilops.
The genus is characterized, among others, by a hairless stem, a ligule which is up to 0.8 mm long with a blunt tip and the spikelets which arise singly from the leaf nodes and can be pressed to the stem. The most problematic weed is jointed goatgrass.
