Aegilops longissima

[GB]
Morphology General Habit
Annual; caespitose. Culms geniculately ascending; 40-110 cm long. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades flat, or involute; 5-10 cm long; 3 mm wide. Leaf-blade surface glabrous, or pilose.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes; not deciduous as a whole, or deciduous as a whole. Racemes 1; single; linear; unilateral, or bilateral; 10-20 cm long; bearing 10-20 fertile spikelets on each. Rhachis tough, or fragile at the nodes. Spikelet packing broadside to rhachis. Rhachis internodes oblong; 1 length of fertile spikelet; when fragile falling with spikelet above. Spikelets solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets absent, or rudimentary; 0-1 in number. Spikelets comprising 2-3 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 12-14 mm long; falling entire; deciduous with accessory branch structures.
Sterile
Basal sterile spikelets absent, or rudimentary; 0-1 in number.
Fertile
Spikelets comprising 2-3 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 12-14 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet. Lower glume oblong; 7-8 mm long; 1 length of upper glume; coriaceous; without keels; 6-7 -veined. Lower glume lateral veins distinct; ribbed. Lower glume apex dentate, or lobed; 2 -fid; muticous, or awned, or awned only on distal spikelets; 1 -awned. Lower glume awn 3-10 mm long. Upper glume oblong; 7-8 mm long; 0.8-0.9 length of adjacent fertile lemma; coriaceous; without keels; 6-7 -veined. Upper glume lateral veins distinct; ribbed; parallel at apex. Upper glume apex dentate, or lobed; 2 -fid; muticous, or awned, or awned only on distal spikelets; 1 -awned. Upper glume awn 3-10 mm long.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic; 8-10 mm long; coriaceous; keeled; keeled above; 5 -veined. Lemma apex dentate; 1-2 -fid; awned only on distal spikelets; 1 -awned. Principal lemma awn subterete below; 40-60 mm long overall. Palea 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2. Ovary pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; hairy at apex. Disseminule comprising a rhachis internode, or inflorescence.
