Poa trivialis
L. Rough Meadow-grassTufted or stoloniferous perennial, upper nodes conspicuous, usually yellowish, culms ascending to erect, to 1 m high. Leaves glabrous, usually scabrous; sheath commonly purplish; blade flat, to 20 cm long and 6 mm wide, abruptly tapered and boat-shaped at apex; ligule acute or pointed-obtuse, 1–3 mm long. Inflorescence an oblong to narrowly ovoid panicle, to 20 cm long and 8 cm wide, the branches tardily or not spreading. Spikelets mostly 2(–3)-flowered, 2.5-4 mm long; glumes subequal, finely pointed, 2–3.5 mm long, the lower 1-nerved, the upper 3-nerved; lemma acutely pointed, 5-nerved, 2.5–3.5 mm long, hairy along the keel and margins in the lower part, occasionally the median nerves also hairy, otherwise glabrous; web copious with hairs c. 2 mm long or more. Flowers Sep.–Jan.

Formerly considered to contain 2 subspecies distinguished on the basis of presence or absence of swollen basal internodes (present in Poa trivialis subsp. sylvicola (Guss.) H.Lindb.), but this character appears to be variable, and probably a response to local growing conditions.
