Morphology General Habit
Annual; culms solitary, or caespitose. Culms decumbent; 10-50 cm long. Ligule a fringe of hairs. Leaf-blades lanceolate; 1-7 cm long; 2-6 mm wide. Leaf-blade margins cartilaginous.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 5-10; borne along a central axis; unilateral; 1-4 cm long; simple, or with branchlets at base of longer racemes. Central inflorescence axis 3-7 cm long. Rhachis wingless; angular; pubescent on surface. Spikelet packing adaxial; irregular. Spikelets solitary, or in pairs. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; subacute, or acute; 2-2.7 mm long; with hairs extending 0-0.5 mm beyond apex; falling entire. Rhachilla internodes elongated between glumes.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; subacute, or acute; 2-2.7 mm long; with hairs extending 0-0.5 mm beyond apex; falling entire. Rhachilla internodes elongated between glumes.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; clasping; 0.33-0.5 length of spikelet; membranous; without keels; 3-5 -veined. Lower glume apex acute. Upper glume oblong; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface glabrous, or pubescent; without hair tufts, or with a transverse fringe of hair. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; with palea, or without significant palea. Lemma of lower sterile floret similar to upper glume; oblong; 1 length of spikelet; membranous; 5 -veined; glabrous, or pubescent; without hair tufts, or with a transverse fringe of hair; acute. Fertile lemma elliptic; 1.5-2.5 mm long; indurate; without keel. Lemma surface striate; unwrinkled, or rugulose. Lemma margins involute. Lemma apex acute, or apiculate. Palea involute; indurate; without keels.
