Chionachne

Perennial or annual. Leaf blades linear; ligule membranous. Inflorescences axillary, of single racemes, each usually supported by a spatheole, often gathered into a spathate compound panicle; racemes bearing pairs of unisexual awnless spikelets, female and male spikelets separated into different zones, female pairs below male pairs, axis fragile between female pairs. Rachis internode and pedicel fused along one margin; callus truncate with central knob. Female zone: sessile spikelet dorsally compressed; lower glume leathery to bony, enveloping spikelet, body smooth or transversely constricted, flanks usually winged above; lower floret sterile, palea usually absent; upper floret pistillate, palea present; pedicelled spikelet reduced to vestigial. Male zone: spikelet pair similar, both or only sessile staminate; lower glume herbaceous, elliptic-oblong.[1] [more]

Coelorachis

[more]

Coix

Annual or perennial. Culms robust, erect or decumbent, sometimes floating, usually solid. Leaves cauline; leaf blades large, usually broad, flat; ligule membranous. Inflorescences many, fascicled in the upper leaf axils, each subtended by a globose or elongated, bony or sometimes softer modified involucral spatheole ("utricle") ; each inflorescence comprising 2 racemes, a female sessile raceme enclosed within the utricle, and a pedunculate male raceme subtended by a prophyll and exserted from the apical pore of the utricle. Female raceme of 1 sessile fertile spikelet accompanied by 2 free stout pedicels, sometimes bearing vestigial spikelets. Female spikelet: lower glume broad, infolding spikelet, membranous with cartilaginous beak; upper glume narrower, keeled; lower floret reduced to a broad hyaline lemma; upper floret with hyaline lemma and palea; lodicules absent; stigmas 2, elongate, exserted from utricle. Male raceme deciduous at maturity, composed of imbricate spikelets borne in pairs or triads, 1(-2) sessile and 1 pedicelled, pedicelled spikelet often reduced in triads. Male spikelets: glumes subequal, herbaceous; lower glume flat on back, margins keeled, keels winged upward, wings with obvious branching veins; upper glume boat-shaped; both florets staminate, lemma and palea hyaline. Caryopsis orbicular, ventrally furrowed, enclosed in utricle.[2] [more]

Cymbopogon

Cymbopogon (lemongrass) is a genus of about 55 species of grasses, (of which the type species is Cymbopogon citratus) native to warm temperate and tropical regions of the Old World and Oceania. It is a tall perennial grass. Common names include lemon grass, lemongrass, barbed wire grass, silky heads, citronella grass,cha de Dartigalongue, fever grass, tanglad, hierba Luisa or gavati chaha amongst many others. [more]

Dimeria

[more]

Erianthus

A Genus in the Kingdom Animalia. [more]

Euchlaena

[more]

Eulalia

A Genus in the Kingdom Animalia.[3] [more]

Hyparrhenia

[more]

Imperata

Imperata is a small genus of grasses known as satintails. Satintail grass species are perennial rhizomatous grasses native to the tropics and warm temperate regions worldwide. They bear solid, erect stems and silky inflorescences. The best known species is Imperata cylindrica, which is recognized as a devastating noxious weed in many places and cultivated as an ornamental plant in others. [more]

Ischaemum

Ischaemum is a genus of tropical grasses in the Poaceae family, with a distribution mainly in the Old World tropics of about 70 species. [more]

Iseilema

[more]

Miscanthus

Miscanthus is a genus of about 15 species of perennial grasses native to subtropical and tropical regions of Africa and southern Asia, with one species (M. sinensis) extending north into temperate eastern Asia. [more]

Saccharum

Sugarcane refers to any of six to 37 species (depending on which taxonomic system is used) of tall perennial true grasses of the genus Saccharum, tribe Andropogoneae). Native to the warm temperate to tropical regions of South Asia, they have stout jointed fibrous stalks that are rich in sugar, and measure two to six metres (6 to 19 feet) tall. All sugar cane species interbreed, and the major commercial cultivars are complex hybrids. [more]

Schizachyrium

[more]

Sorghastrum

[more]

Sorghum

Sorghum is a genus of numerous species of grasses, some of which are raised for grain and many of which are used as fodder plants either cultivated or as part of pasture. The plants are cultivated in warmer climates worldwide. Species are native to tropical and subtropical regions of all continents in addition to Oceania and Australasia. [more]

Themeda

Perennial or annual, often coarse. Culms tufted. Leaf sheaths keeled; leaf blades linear; ligule short, membranous or papery. Inflorescence a leafy compound panicle composed of short racemes; each raceme on a short peduncle subtended by a sheathing spatheole, loosely arranged or gathered into fan-shaped spathate fascicles. Raceme comprising 2 pairs of large sessile homogamous spikelets at base forming an involucre, with 1-2(-5) fertile pairs above and a terminal triad, these usually deciduous, rarely raceme shed as a whole; internodes and pedicels linear. Sessile spikelet subterete or dorsally compressed; callus mostly acute to pungent, sometimes obtuse, bearded; lower glume usually leathery, margins rounded, incurving, keeled only near apex, obtuse; upper glume awnless; lower floret reduced to a hyaline lemma; upper lemma stipitiform, entire, passing into a geniculate awn with pubescent column, occasionally awnless. Pedicelled spikelet mostly larger than sessile, narrowly lanceolate, resembling homogamous; callus slender, pedicel-like; true pedicel reduced. x = 10.[4] [more]
