Plants shortly stoloniferous. Culms 30-110 cm, erect or geniculate
at the base. Basal leaves: sheaths closed to near the top; ligules 0.5-1
mm, truncate; blades 10-40 cm long, 2-6(8.5) mm wide, usually with
hairs to 2 mm. Cauline leaves: sheaths closed for nearly
their entire length, pubescent; ligules 5-8 mm, acute; blades 10-40
cm long, 2-6 mm wide, usually pubescent, margins very narrowly cartilaginous. Panicles 6-20
cm long, 2-6 cm wide, erect or nodding; branches 4-35 mm, flexuous
or straight, with 1-4 spikelets. Spikelets 10-26 mm, with 2-4 florets; rachilla
internodes about 2.5 mm, hairs 3-7 mm. Glumes scabrous on the
veins. Lower
glumes 7-20 mm, 1(3)-veined; upper
glumes 10-26 mm, 3-veined; calluses bearded, hairs 2-5 mm; lemmas 8-16
mm, awned, awns 12-26 mm, terete below the bend; paleas 8-12 mm; anthers 5-7

Avenula pubescens is native to Eurasia, where it grows in meadows,
pastures, and woodland clearings. The most widespread taxon is Avenula
pubescens (Huds.) Dumort. subsp. pubescens, which differs from Avenula
pubescens subsp. laevigata (Schur)
Holub in having smaller spikelets (10-17 mm long with 2-3 florets, versus 15-26
mm long with 3-4 florets). It has been collected in southern Ontario,
Ile d'Anticosti in Quebec, and in New England, but is not known to be
established in Canada.
