Bromus remotiflorus

HABIT Perennial; caespitose. Culms erect; 60–128 cm long; 1.75–2 mm diam.; 6–7 -noded. Culm-nodes pubescent. Leaves cauline. Leaf-sheaths tubular for much of their length; pubescent. Ligule an eciliate membrane; 1–2 mm long. Leaf-blades 18–38 cm long; 5–9 mm wide. Leaf-blade surface scaberulous; rough on both sides; pubescent; hairy abaxially.

INFLORESCENCE Inflorescence a panicle. Peduncle pubescent above.

Panicle open; elliptic; nodding; 20–30 cm long; 3–6 cm wide. Primary panicle branches drooping; 3–6 -nate; whorled at most nodes; bearing 5–14 fertile spikelets on each lower branch. Panicle branches capillary; scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 6–10 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 20–35 mm long; 4–6 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume linear; 4–7 mm long; 0.5–0.6 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume linear; 8–12 mm long; 0.8 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume apex acuminate.

FLORETS Fertile lemma lanceolate; 10–15 mm long; herbaceous; keeled; 7 -veined. Lemma surface asperulous; pubescent; hairy on veins. Lemma apex acute; awned; 1 -awned. Principal lemma awn apical; 6–12 mm long overall. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; membranous. Anthers 3; 1.5–2.5(–3) mm long. Ovary with a fleshy appendage above style insertion; pubescent on apex.

FRUIT Caryopsis with adherent pericarp; oblong; 8–10 mm long; hairy at apex; apex fleshy. Hilum linear.

DISTRIBUTION Asia-temperate: China and eastern Asia. Asia-tropical: Malesia.
