| Aegilops is a genus of Eurasian and North American plants in the grass family, Poaceae. They are known generally as goatgrasses. Some species are known as invasive weeds in parts of North America
These are annual plants, sometimes from rhizomes. The taller species reach about 80 centimeters in maximum height. The flat leaves are linear to narrowly lance-shaped, and are up to 15 centimeters long and one wide. The inflorescence is a spike with 2 to 12 solitary spikelets each up to 1.2 centimeters long. Some spikelets have one or three awns, and some have none
Some Aegilops are known as weeds. A. cylindrica, which is commonly known as jointed goatgrass, infests wheat fields, where it outcompetes wheat plants, reducing yields. Its seeds mix with wheat grains at harvest, lowering the quality of the crop. It can also harbor pests such as the Russian wheat aphid (Diuraphis noxia) and pathogenic fungi. Other Aegilops are weeds of rangeland and wildland habit |
