Morphology General Habit
Perennial; caespitose. Butt sheaths thickened and forming a bulb; persistent and investing base of culm; with compacted dead sheaths. Culms erect; 10-40 cm long. Leaf-sheaths pubescent, or hirsute. Ligule an eciliate membrane; 0.5-0.7 mm long. Leaf-blades 8-15 cm long; 1.5-4 mm wide. Leaf-blade surface pilose; hairy adaxially. Leaf-blade margins cartilaginous; scaberulous. Leaf-blade apex acute; hooded.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle tipped by a glumaceous appendage (treated as sterile spikelets). Panicle capitate; ovate; 1-2 cm long; 1-1.5 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis, or with lateral stumps on axis. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets represented by a single scale; 2 in number; ovate. Basal sterile spikelet glumes membranous. Spikelets comprising 2(-4) fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; acute to acuminate; 4.5-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
Sterile
Basal sterile spikelets represented by a single scale; 2 in number; ovate. Basal sterile spikelet glumes membranous.
Fertile
Spikelets comprising 2(-4) fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; acute to acuminate; 4.5-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume ovate; 3-4 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein ciliolate. Lower glume lateral veins absent. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 1.5-2 mm long. Upper glume ovate; 3-4 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein ciliolate. Upper glume lateral veins absent. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 1.5-2 mm long.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic, or oblong; 3-4 mm long; membranous; without keel; rounded except near apex; 3-5 -veined. Lemma apex dentate; 3-5 -fid; awned; 3-5 -awned. Principal lemma awn 1.5-2 mm long overall. Lateral lemma awns arising on apex of lobes; shorter than principal. Palea 1 length of lemma; 2 -veined. Palea keels pubescent. Palea apex dentate; 2 -fid; awned; awns 0.5-1 mm long.

Anthers 3; linear, or oblong; 1.6-3.2 mm long; yellow. Stigmas 2; terminally exserted. Ovary pubescent on apex.
