Poa trivialis L.[FNA24, HC, HC2]
rough-stalk bluegrass
Publication: Sp. Pl. 1: 67. 1753.
Origin: Introduced from Europe
selected vouchers: WTU
Notes: FNA24: "Poa trivialis is an introduced European species. Only Poa trivialis subsp. trivialis is present in the Flora region. Several cultivars have been planted for pastures and lawns, and have often escaped cultivation. Poa trivialis sometimes grows with P. paludigena, but has distinctly longer ligules and anthers. It is easily recognized by its flat blades, long ligules, sickle-shaped lower glumes, prominent callus webs, and lemmas with pubescent keels and pronounced lateral veins."
