Lindbergella sintenisii
HABIT Annual. Culms decumbent; 8–21 cm long. Ligule an eciliate membrane; 2–3 mm long; lacerate. Leaf-blades 2–6 cm long; 1–2 mm wide. Leaf-blade margins scaberulous. Leaf-blade apex acuminate.
INFLORESCENCE Inflorescence a panicle.
Panicle open; ovate; 2–11 cm long; 1–9 cm wide. Primary panicle branches spreading; 2–5 -nate; whorled at most nodes; branching divaricately; 1–5 cm long.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 2–5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 3–4.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes eventually visible between lemmas.
GLUMES Glumes persistent; similar; with lower narrower than upper; shorter than spikelet; similar to fertile lemma in texture. Lower glume elliptic; 3 mm long; 0.8 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface scabrous. Lower glume apex acute. Upper glume elliptic; 3.5 mm long; 0.8 length of adjacent fertile lemma; membranous; with hyaline margins; 1-keeled; 3 -veined. Upper glume surface scabrous; rough on veins. Upper glume apex acute.
FLORETS Fertile lemma elliptic; 4 mm long; membranous; keeled; 3 -veined. Lemma midvein scaberulous. Lemma surface scaberulous; rough on veins; pilose; hairy between veins. Lemma apex acute; muticous, or mucronate. Palea 1 length of lemma. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 2; ovate; membranous; with a small lateral lobe; acute. Anthers 3; 0.5 mm long. Stigmas 2.
FRUIT Caryopsis with adherent pericarp; fusiform; sulcate on hilar side; 2.5–2.75 mm long. Embryo 0.1 length of caryopsis. Hilum punctiform.
DISTRIBUTION Asia-temperate: western Asia.
NOTES Poeae. Bor.
