Quite frequent in bare dry ground, including gravelly road verges and walls.

Spikelets c 2.5-4 mm long excluding awns.  Stem typically 5-10 cm tall.

ID: 2 spikelets per flower, the tops of the lemmas just short of the tops of the glumes, but the lemmas having awns which project well past the glumes.  Panicle very narrow, bearing spikelets on branches little longer than themselves, in total contrast to other Hair-grasses.

Other features: A low annual forming small but often numerous tufts, flowering Apr-Jun.  Leaf-sheaths smooth, not rough as in Silver Hair-grass.  Spikes hidden in silvery sheaths before flowering.  The two awns often cross, as in the top spikelet in the bottom left picture.  Awn arises at about 1/3 way up back of lemma.  The two spikelets arise about 1/8 of their length apart.
