Trisetum flavescens (L.) P. Beauv.[FNA24, HC, HC2]
yellow false oat

Publication: Enum. Stirp. Transsilv. 3: 263. 1816.

Origin: Introduced

selected vouchers: Not at WTU; WS?

Notes: "This European species has been introduced in many areas of the U. S. and is reported for Wash." [H&C].

FNA24: "Trisetum flavescens grows in seeded pastures, roadsides, and as a weed in croplands. Native to Europe, west Asia, and north Africa, it was introduced into the Flora region because of its drought resistance, wide soil tolerance, and high palatability to domestic livestock. It is one of the few range plants known to contain calcinogenic glycosides, which can lead to vitamin D toxicity in grazing animals (Dixon 1995). This species seems not to have persisted in southern Ontario (Michael Oldham, pers. comm.). Several infraspecific taxa have been recognized; no attempt has been made to determine which are present in the Flora region."
