Spikelets 3? mm long, ovate, laterally compressed; not bulbiferous; florets 2?, proximal hermaphroditic, distal generally pistillate; rachilla Ed in Tables two (approach 1) and 3 (system two). No resistant mutants had been obtained internodes terete, smooth, glabrous, a lot more or significantly less concealed or exposed, distal internode less than 1/2(?/4) length of distal lemma; glumes unequal, smooth, distinctly keeled, keels smooth; apex acuminate to acute or obtuse, sharp pointed or slightly blunt; decrease glumes 1?.two mm long, 1-veined, narrowly lanceolate, usually slightly sickle shaped, or subulate, apex acute; upper glumes 1.5?.five mm extended, shorter than or subequaling lowest lemma,3-veined, lanceolate to oblanceolate, apex obtuse to acute; calluses glabrous; lemmas two.two?.three(?) mm lengthy, broadly lanceolate, green to light green, at times slightly anthocyanic, distinctly keeled, smooth all through, keels, marginal, and usually intermediate veins moderately to densely crisply puberulent to extended villous, seldom glabrous all through, amongst veins glabrous, intermediate veins prominent, margins and edges smooth, apices obtuse to acute; paleas keels smooth, quick to extended villous, rarely glabrous more than the keels.

Spikelets 3? mm lengthy, ovate, laterally compressed; not bulbiferous; florets two?, proximal hermaphroditic, distal normally pistillate; rachilla internodes terete, smooth, glabrous, a lot more or much less concealed or exposed, distal internode much less than 1/2(?/4) length of distal lemma; glumes unequal, smooth, distinctly keeled, keels smooth; apex acuminate to acute or obtuse, sharp pointed or slightly blunt; decrease glumes 1?.two mm long, 1-veined, narrowly lanceolate, typically slightly sickle shaped, or subulate, apex acute; upper glumes 1.five?.5 mm lengthy, shorter than or subequaling lowest lemma,3-veined, lanceolate to oblanceolate, apex obtuse to acute; calluses glabrous; lemmas two.2?.three(?) mm long, broadly lanceolate, green to light green, sometimes slightly anthocyanic, distinctly keeled, smooth throughout, keels, marginal, and generally intermediate veins moderately to densely crisply puberulent to extended villous, hardly ever glabrous all through, among veins glabrous, intermediate veins prominent, margins and edges smooth, apices obtuse to acute; paleas keels smooth, quick to extended villous, rarely glabrous over the keels. Flowers cleistogamous to chasmogamous; lodicules 0.45?.5 mm long, broadly lanceolate to ovate, with 1 (seldom two) brief lateral lobe(s); anthers 0.6?.1 mm extended, oblong prior to dehiscence, usually vestigial in distal flowers of a spikelet. Caryopses 1.six?.8 mm long, elliptical in side-view, subcylindrical in cross-section, light brown, sulcus practically flat, hilum 0.15 mm extended, oval, grain totally free or adherent for the palea. 2n = 28. Distribution. The species is distributed Worldwide, mostly in temperate and subtropical regions. In Mexico it's recorded from all states, except Campeche, Nayarit, Quintana Roo, Sinaloa, Tabasco, and Yucat . Ecology. The species can be a gynomonoecious, ruderal annual (infrequently a shortlived perennial), and is identified in waste ground, lawns, gardens, trails, sidewalks, roadsides, fields ranging from sea level to over 4500 m. The species can potentially flower all through the year.
