Poa celsa Edgar
Erect, light purplish-green perennial tufts to 50 cm tall, culms overtopping leaves; new shoots extravaginal; laminae persistent. Sheaths purplish, to later greyish, subcoriaceous, nerves not very distinct, abaxially minutely ciliate-scabrous especially on midnerve especially just below, and sometimes for a short distance above ligule, the minute teeth often very dense; ligule c. 1.5-3 mm long, entire, rounded across smooth top, sometimes erose, ciliate- scabrous abaxially; lamina 6-20 cm × (2)-3- 6 mm, folded or flat, subcoriaceous, abaxially ± minutely scabrous on nerves, adaxially scabrous in lower half and along nerves above, margins scabrous, with some stiff short hairs at collar region, tip + curved, acuminate to often apiculate. Culms 10-40 cm tall, erect, scabrous below panicle. Panicle 8-15 cm long, lax, with large spikelets on slender spreading scabrous branchlets. Spikelets 6- 8 mm long, (2)-3-4-(5)-flowered, green or purplish. Glumes + equal, 3-nerved, ovate-elliptic, margins, nerves and internerves near tip ± scabrous; lower glume 3.5-5.5 mm long, subacute, upper 4-5.5-(6) mm long, subobtuse. Lemma 4.5- 6 mm long, 5-nerved, oblong, obtuse, ciliate-scabrous on nerves, margins, and often on internerves. Palea 3.5-4.5 mm long, scabrous between ciliate-scabrous keels. Lodicules 0.5-0.6 mm long. Callus with tuft of a few long crimped hairs. Rachilla c. 1 mm long, with a few long hairs, projection twice as long. Anthers 1-1.5 mm long. Caryopsis c. 1-2 × 0.5 mm.
