Crypsis hadjikyriakou

HABIT Annual; culms solitary. Culms erect, or prostrate; 1–30 cm long. Lateral branches lacking, or sparse. Leaf-sheaths inflated; longer than adjacent culm internode; without keel; ribbed; smooth; glabrous on surface, or pilose; with tubercle-based hairs; outer margin glabrous, or hairy. Ligule a fringe of hairs. Leaf-blades flat, or involute; 0.5–2 cm long; 1–5 mm wide; stiff; glaucous. Leaf-blade surface ribbed; scabrous; rough adaxially; pilose; sparsely hairy; hairy on both sides; with tubercle-based hairs. Leaf-blade margins scabrous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle; comprising 8–15 fertile spikelets; subtended by an inflated leaf-sheath; embraced at base by subtending leaf, or enclosed.

Panicle capitate; elliptic, or ovate; 0.5–1 cm long; 0.4–0.5 cm wide. Panicle axis glabrous.

Spikelets solitary, or in pairs. Fertile spikelets sessile, or sessile and pedicelled.

STERILE SPIKELETS Basal sterile spikelets well-developed; 1–2 in number.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets cuneate; laterally compressed; 3–4 mm long; falling entire.

GLUMES Glumes similar; with lower narrower than upper; shorter than spikelet. Lower glume lanceolate; 2–2.5 mm long; 0.9 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scabrous; eciliate. Lower glume lateral veins absent. Lower glume margins eciliate. Lower glume apex caudate. Upper glume lanceolate, or ovate; 2–2.5 mm long; 0.9 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume margins eciliate. Upper glume apex caudate.

FLORETS Fertile lemma lanceolate; 2–2.5 mm long; membranous; keeled; 1 -veined. Lemma apex caudate. Palea 1.2–2 mm long; 2 -veined. Palea apex dentate; 4 -fid.

FLOWER Lodicules absent. Anthers 3; 2.5 mm long; yellow, or brown.

FRUIT Caryopsis ellipsoid, or oblong; 1.5–2 mm long. Embryo 0.75 length of caryopsis.

DISTRIBUTION Asia-temperate: western Asia.
