Secale ciliatiglume
HABIT Perennial; caespitose. Culms 60–110 cm long. Culm-internodes distally glabrous, or pilose. Leaf-sheaths pubescent. Leaf-sheath oral hairs lacking. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades 7–26 cm long; 2–5(–10) mm wide. Leaf-blade surface pubescent, or pilose. Leaf-blade margins smooth, or scaberulous.
INFLORESCENCE Inflorescence composed of racemes. Peduncle pubescent above.
Racemes 1; single; bilateral; 3.5–5 cm long; 5–10 mm wide. Rhachis fragile at the nodes; ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes oblong; 2.5–3.5 mm long; falling with spikelet above.
Spikelets solitary. Fertile spikelets sessile.
FERTILE SPIKELETS Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 16–18 mm long; falling entire; deciduous with accessory branch structures.
GLUMES Glumes similar; shorter than spikelet; thinner than fertile lemma. Lower glume linear; 10–11 mm long; 1 length of upper glume; membranous; 1-keeled; keeled all along; 1 -veined. Lower glume primary vein ciliate. Lower glume lateral veins absent. Lower glume surface pubescent. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 2 mm long. Upper glume linear; 10–11 mm long; 0.6–1 length of adjacent fertile lemma; membranous; 1-keeled; keeled all along; 1 -veined. Upper glume primary vein ciliate. Upper glume lateral veins absent. Upper glume surface pubescent. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 2 mm long.
FLORETS Fertile lemma elliptic; 10–18 mm long; coriaceous; keeled; 5 -veined. Lemma midvein pectinately ciliate. Lemma surface smooth, or scabrous. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn (11–)25–35 mm long overall; limb scabrous. Palea 8–16 mm long; 2 -veined. Palea keels ciliolate. Apical sterile florets 1 in number; barren.
FLOWER Lodicules 2; ciliate. Anthers 3; 5 mm long; yellow. Ovary with a fleshy appendage below style insertion; pubescent on apex.
FRUIT Caryopsis with adherent pericarp. Hilum linear.
DISTRIBUTION Asia-temperate: western Asia.
