Cutandia stenostachya

HABIT Annual. Culms erect, or geniculately ascending; slender; 10–38 cm long. Leaf-sheaths loose; smooth. Ligule an eciliate membrane; 1–2 mm long. Leaf-blades 2–8 cm long; 0.5–1 mm wide.

INFLORESCENCE Inflorescence a panicle; comprising 7–15 fertile spikelets.

Panicle open; linear; 3–12 cm long; bearing few spikelets. Primary panicle branches 1–2 -nate; indistinct the panicle almost racemose. Panicle branches stiff; straight; angular; with prominent pulvini.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong; angular; 0.5–2 mm long.

FERTILE SPIKELETS Spikelets comprising 2–5 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 5–14 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2.4–2.9 mm long; pubescent.

GLUMES Glumes persistent; dissimilar; shorter than spikelet. Lower glume lanceolate; 1.3–2.6 mm long; 0.5–0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein smooth, or scaberulous. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume lanceolate; 2.3–4 mm long; 0.8–1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein smooth, or scaberulous. Upper glume apex obtuse.

FLORETS Fertile florets appressed to rhachilla. Fertile lemma lanceolate; 2.7–4 mm long; membranous; keeled; 3 -veined. Lemma apex emarginate to obtuse. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; membranous. Anthers 3; 1 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp; 2.5 mm long. Hilum punctiform.

DISTRIBUTION Europe: southeastern. Asia-temperate: western Asia.

NOTES Poeae. Fl Turk.
