upper glume

Upper glume subequaling spikelet; only branch or branchlet tips extending into a bristle, rarely a solitary bristle below a few spikelets.

Upper glume clearly mucronate, shorter than spikelet; spikelets planoconvex, acuminate; back of upper lemma lying against rachis.

Upper glume rounded on back, only keeled below apex, keel winged or not.

Lateral veins of lower lemma smooth; upper glume rounded; upper lemma apiculate, exceeding lower lemma.

Culms up to 6 m; upper glume of sessile spikelet glabrous.

Perennials; leaf sheath slightly shorter than blade; upper glume shorter than lowest lemma.

Lower glume longer than upper glume; panicle open, branches divaricate, bearded in axils.

Upper glume very small, usually vein less; spikelets on long capillary pedicels.

Culms up to 1. 5 m; upper glume of sessile spikelet thinly pilose.

Spikelets brown, obovate; upper glume puberulous, fringed only above middle.

Spikelets hispid; upper glume of sessile spikelet winged on keel; callus hairs ca. 2 mm.

upper glume equal to lower glume, boat-shaped.

Anthers ca. 0. 8 mm; upper glume distinctly keeled and broadly winged from base to apex.

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

This is a distinctive species, clearly differing from others in China by its tough, in rolled leaf blades and awned upper glume.

Glumes membranous, 1-veined, lower glume ca. 0. 8 mm, upper glume ca. 1 mm, falling off when mature.

upper glume equal to spikelet, inconspicuously scabrous to shortly hispid along veins, cuspidate to awn-tipped;

upper floret bisexual, lemma hyaline, a little shorter than upper glume, apex shortly 2-toothed, awned from sinus;

upper glume papery, elliptic, shiny, margins ciliate with silky white or pinkish hairs, apex caudate;

lower floret barren, lemma similar to upper glume, finely acute, palea poorly developed;

upper glume ovate-lanceolate, as long as spikelet, glabrous or with very short hairs on keel, subacute;

lower floret staminate, lemma similar to upper glume, palea well developed;

upper glume lanceolate, shiny, obscurely 5-veined, apex subacute, sometimes with subapical awn-point;

lower lemma similar to upper glume, palea absent or present and well developed;

lower lemma similar to upper glume, palea well developed but floret barren;

upper glume boat-shaped, resembling lower glume in texture and color;

upper glume adnate to rachis, equaling lower glume, thin, acute;

lower lemma similar to upper glume, palea poorly developed;

lower lemma similar to upper glume, back flat to slightly sulcate;

lower lemma similar to upper glume, palea well developed;

upper glume weakly keeled or rounded on back, acuminate;

lower floret neuter or infrequently staminate, lemma as long as upper glume, ovate, 7-veined;

upper glume boat-shaped, apex mucronate or awned;

lower lemma similar to upper glume, palea absent;

glumes unequal, lower glume ovate, ca. 3 mm, upper glume oblong-ovate, as long as spikelet;

upper glume subequal to lower glume, scabrid along keel, apex acute;

upper glume 5-veined, usually tuberculate-setose on veins;

upper glume villous on keel, apex acute;

upper glume ovate-oblong, as long as spikelet, 5-veined, acute;

upper glume ovate, as long as spikelet, 1-veined, acute;

glumes lanceolate, unequal, lower glume ca. 0. 3 mm longer than upper glume, keel scabrid, apex acute;

upper glume scabrid on keel toward apex;

upper glume acute or with a ca. 0. 5 mm mucro;

upper glume scabrid on upper keel;

glumes mostly strongly keeled, unequal, or subequal, lower glume 1- or 3-veined, upper glume 3(or 5)-veined;

glumes obtuse, lower glume ca. 1. 2 mm, upper glume ca. 2 mm;

upper glume with mucro to 0. 5 mm;
