barnyard grass, or large barnyard grass

Publication: Ess. Agrostogr. 53, 161, 169, pl. 11, f. 2.

Origin: Introduced from Eurasia

selected vouchers: WTU

Notes: FNA25: "Echinochloa crus-galli is a Eurasian species that is now widely established in the Flora region, where it grows in moist, disturbed sites, including rice fields. Some North American taxonomists have interpreted Echinochloa crus-galli much more widely; others treat it as here, but recognize several infraspecific taxa based on such characters as trichome length and abundance, and awn length. There are several ecological and physiological ecotypes within the species, but the correlation between most of these and the species morphological variation has not been established, so no infraspecific taxa are recognized here."
