Puccinellia raroflorens Edgar
Low-growing perennial to 4.5 cm, sometimes forming a loosely woven mat to 2 m diam. or more, usually almost entirely covered by soil, rarely flowering and only the short very narrow dull green curved leaves visible; branching extravaginal. Leaf-sheaths smooth, submembranous, much wider than leafblades, nerves few, distinct; ligule 0.2—0.6 mm, subhyaline, obtuse or truncate; leaf-blades 1-3 cm × 0.2—0.5 mm, setaceous, involute, smooth, subacute, margins minutely scaberulous. Culms entirely enclosed by leaf-sheaths. Panicle rarely present, 10—16 mm long, enclosed by leaf-sheaths for about half its length, overtopped by leaf-blades, bearing up to 12 spikelets, lowermost branches enclosed by leaf-sheaths, smooth, uppermost branches scaberulous. Spikelets 3-4—(4.8) mm, 4-6-flowered, green to brownish green. Glumes unequal, ovate, obtuse, submembranous; lower glume 0.6—1 mm, 1-nerved; upper glume 1.1-1.4 mm, 3-nerved. Lemma 1.8—2.5 mm, 5-nerved, ovate-elliptic, entirely glabrous, midnerve ± reaching subacute tip. Palea ± = lemma, keels scabrous in upper 2/3 Rachilla 0.4-0.5 mm. Anthers 0.4-0.6 mm. Caryopsis 1.2— 1.6 × 0.6-0.7 mm. Endemic.
Gramen perenne humile, tegetem laxam interdum formans, plerumque solo fere omnino amictum, raro florens, nullo modo visibile praeter folia parva, perangusta, obscuroviridia, recurva; Puccinelliae strictae affine foliis setaceis, a qua differt innovationibus extravaginalibus, paniculis inter folia paene celatis, lemmatibusque omnino glabris.
