scabrid

Nutlets ovoid to oblong, smooth or dotted, scabrid, membranous winged in a few species.

branches slender, flexuous, scabrid, with the spikelets in pairs and clustered toward the ends of the branches.

Leaves opposite, usually glaucescent, linear or lanceolate, veins parallel, base slightly connate, margin scabrid.

branches in distant pairs, slender, often flexuous, scabrid, lower ca. 7 cm, bearing up to 4 spikelets in upper part.

Culms self-supporting, nodal sheath scars without corky collar; spikelets not pendulous; culm sheath adaxially distally scabrid.

palea subequaling and almost enclosed by lemma, keels close together, prominent, scabrid, depressed between keels.

branches steeply ascending, scabrid angled, with spikelets from the base.

palea smooth or proximally with sparse hooks between keels, keels scabrid, sometimes medially pilulose.

homogamous spikelets scabrid-pectinate on upper keels.

branches ascending or spreading, scabrid.

Panicle branches sparsely to moderately scabrid from the base.

branches few to many at each node, branches and pedicels all slender, scabrid.

branches capillary, smooth in lower part, upper part scabrid.

pedicels scabrid, longer of pair twice spikelet length.

palea glabrous, area with slender hooks or crisply pilulose between keels, keels scabrid.

axis and pedicels glabrous or scabrid along angles.

branches in whorls, bare at base, slightly scabrid.

Glumes scabrid along keel; culms not swollen at base.

branches mostly unbranched, flexuous, scabrid or almost smooth, bearing 1 or rarely 2 spikelets.

Spikelets 3-awned (from upper glume and both lemmas); lower glume scabrid, apex 2-cleft; nodes of culm pubescent.

Culms and outer surface of leaf blades scabrid or shortly spinulose.

lower glume thinly cartilaginous, back pilose with silky hairs twice length of spikelet, keels scabrid, apex acuminate;
