Diheteropogon Stapf

Genus

Angiosperms > Poales > Poaceae

Characteristics

Annuals or perennials. Leaf-blades linear or tapering from a cordate base; ligule membranous. Inflorescence composed of paired racemes, these terminal on the culm or gathered into a scanty spathate false panicle; racemes not deflexed, with 1–many homoganous pairs; internodes and pedicels linear, ciliate. Sessile spikelet dorsally compressed; callus pungent, deeply inserted into the hollow top of the internode; lower glume coriaceous, hollowed or deeply grooved on the back, 2-keeled, the keels dorsal and each 2–7-nerved; lower floret reduced to a hyaline lemma; upper lemma hyaline, bilobed, passing between the lobes into an awn with puberulous to hirsute column. Caryopsis lanceolate to oblanceolate. Pedicelled spikelet ♂, lanceolate, herbaceous, larger than the sessile.
More
Racemes in pairs, terminal or arranged in a scanty spatheate false panicle, rarely solitary, clearly exserted from the spatheoles; peduncles much longer than the racemes, erect at maturity; internodes and pedicels linear, long-ciliate on both margins with ± ascending hairs.
Sessile spikelet dorsally compressed, lanceolate; callus very pointed; inferior glume with a narrow median groove, coriaceous; inferior floret reduced to a hyaline lemma; superior floret bisexual, its lemma bilobed with a terminal awn; awn bigeniculate, shortly pilose.
Annuals or caespitose perennials, often glaucous and tinged with red; culms not branched; ligules truncate; leaf laminas tapering to a fine point.
Pedicelled spikelet male or sterile, much longer than the sessile spikelet, dark red, coriaceous.
