Stenostachys Enysii


Plants perennial, stoloniferous. Culms 25-80 cm tall, 0.5-3 mm thick, drooping; nodes 2-3, more or less geniculate below; internodes glabrous or very slightly glabrous, upper internode elongating after flowering, sometimes reaching 60 cm [Note: this last characteristic is developed to an even greater extent in Connorochloa].

Leaves: sheaths 6-8 cm long, pubescent or with erect to retrorse hairs. Auricles to 0.75 mm long, often minute. Ligule 0.3-0.75 mm long, erose, truncate to rounded or obtuse. Blade to 20 cm long, 2-4 mm wide, flat; abaxial surface glabrous or densely retrorsely hairy over the veins; adaxial surface both scabrous and hairy; margins scabrous.

Inflorescences often hidden in the tussocks, 5-13 cm long, with 10-25 spikelets; rachis: surfaces glabrous, edges usually scabrous, extending beyond the distal spikelet by 0.5-4.5 mm; middle internodes 4-7 mm.

Spikelets solitary, not pedicillate, 10-16 mm long, with 3-4 florets; disarticulation below the florets.

Glumes more or less equal, 6-9 mm long, 0.2-0.4 mm wide, asymmetrically keeled, becominga awnlike distally, margins smooth or scabridulous. Calluses about 0.25 mm, blunt, surrounded by minute hairs. Lemmas 7-10 mm long, glaucous, mostly smooth and blabrous, veins scabrous distally, tip bifid; awn 1-3.5 mm long. Paleas 6-9 mm long, shorter than the lemma; keels coarsely scabrous; intercostal region retuse.

Lodicules 1-1.25 mm long, with a few apical hairs. Anthers 1.8-3 mm long, Caryopses about 6 mm long.
