    Habit
    Perennial; caespitose. Rhizomes elongated; pachymorph. Culms erect; 30-80 cm long; 2-5 mm diam.; woody; without nodal roots. Culm-internodes terete; smooth; distally glabrous. Lateral branches dendroid; intravaginal. Branch complement one to several; with subequal branches. Culm-sheaths persistent; 1-4.5 cm long. Culm-sheath ligule 0.1-0.2 mm high. Culm-sheath blade triangular; deciduous; 0.5-0.8 cm long. Leaves 3-15 per branch. Leaf-sheaths 0.9-1.2 cm long; keeled; striately veined; puberulous. Ligule an eciliate membrane; 0.3-0.5 mm long; scarious; erose. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.05-0.1 cm long. Leaf-blades lanceolate; 1-2.5 cm long; 1.5-3 mm wide; stiff. Leaf-blade surface glabrous. Leaf-blade margins cartilaginous. Leaf-blade apex acute; simple, or apiculate.
    Inflorescences
    Inflorescence a panicle; comprising 7-15 fertile spikelets; embraced at base by subtending leaf. Panicle contracted; linear; continuous, or interrupted; 1-2(-3) cm long. Primary panicle branches appressed; 2-3 -nate; indistinct the panicle almost racemose. Panicle axis with lower internodes 0.8-1.2 cm long; angular; pubescent. Spikelets appressed; solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 5.5-7.2 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 5.5-7.2 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.4-0.7 mm long; 0.75-1 length of upper glume; membranous; without keels. Lower glume lateral veins absent, or obscure. Lower glume surface puberulous. Lower glume apex acute. Upper glume ovate; 0.8-1 mm long; 0.1-0.13 length of adjacent fertile lemma; membranous; without keels. Upper glume lateral veins absent, or distinct. Upper glume surface pubescent. Upper glume apex obtuse.
    Florets
    Basal sterile florets similar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret lanceolate; 4-6 mm long; 0.5-0.75 length of fertile lemma; chartaceous; 5 -veined; pubescent; hairy above; acute. Lemma of upper sterile floret lanceolate; 5-8 mm long; chartaceous; pilose (at tip); acute. Fertile lemma lanceolate; 6-8 mm long; coriaceous; without keel; 7-8 -veined. Lemma apex acute. Palea lanceolate; 5-6 mm long; 4 -veined. Palea apex undifferentiated, or pubescent.
    Flowers
    Lodicules 3; 0.6-1.2 mm long; membranous. Anthers 3; 2-3 mm long.
