Brachypodium phoenicoides

(L.) Roem. & Schult.
Common names: Thinleaf falsebrome
Treatment appears in FNA Volume 24. Treatment on page 190.

Plants perennial; rhizomatous, rhizomes branched. Culms (30) 40-90 (110) cm, erect, with 3-5 nodes; nodes pubescent. Sheaths antrorsely scabrous, usually glabrous, sometimes pilose; ligules (0.4) 0.7-1.5 (1.8) mm, ciliate; blades 10-40 cm long, 3-5 mm wide, flat and more or less lax or convolute and somewhat rigid, particularly when dry, surfaces scabrous, usually glabrous, sometimes pilose, adaxial surfaces sparsely hairy, scabrous, with all veins more or less equally prominent. Racemes 10-20 (30) cm, with 5-9 (15) scarcely overlapping spikelets; pedicels (0.7) 1-2 (3.2) mm. Spikelets (20) 30-60 (80) mm, often slightly falcate, terete or subterete, with (7) 9-18 (31) florets. Lower glumes 4-7 mm, (4) 5 (7) -veined; upper glumes 5-8 mm, 7-8 (9) -veined, mucronate or shortly awned; lemmas (7.5) 8-10.3 (11) mm, apices abruptly narrowed, mucronate or awned, awns 1-2.5 mm; paleas 6.5-10.5 mm, keeled, keels ciliate or hairy; anthers 4-6 mm. Caryopses 5-7 mm. 2n = 28.

Discussion

Brachypodium phoenicoides is native to dry, usually open, and often sandy habitats of the northern Mediterranean region. In the Flora region, it is currently known only from Sonoma County, California, where it is established on coastal sand dunes.
