Genera

[ Back to top ]

Dactyloctenium

Dactyloctenium is a genus of grass in the Poaceae family. The approximately ten species in this genus are known generally as crowfoot grass. They are mainly native to Africa and Australia. [more]

Desmostachya

Perennials, rhizomatous. Leaf blades linear or inrolled; ligule a line of hairs. Inflorescence a narrow spikelike panicle composed of numerous, short, 1-sided racemes of sessile, closely imbricate, biseriate spikelets on a long central axis. Spikelets falling entire, strongly laterally compressed, florets several to many; glumes shorter than lemmas, unequal, membranous, 1-veined, lightly keeled, acute; lemmas papery to leathery, 3-veined with lateral veins evanescent upward, glabrous, keeled, acute; palea equal to or slightly shorter than lemma. Caryopsis ovoid, trigonous.[1] [more]

Distichlis

[more]

Eleusine

Annuals or tussocky perennials. Culms compressed. Leaf sheaths strongly keeled; leaf blades linear, usually folded; ligule membranous, usually with a ciliate fringe. Inflorescence of digitate or subdigitate spikelike racemes clustered at the top of the culm; racemes with closely imbricate, biseriate spikelets, terminating in a fertile spikelet. Spikelets laterally compressed, florets several, disarticulating between the florets (except the cultivated species E. coracana) ; glumes shorter than lemmas, persistent, 1-3(-7) -veined, keeled, awnless; lemmas membranous, 3-veined, glabrous, strongly keeled, keel thickened with 1-3 closely spaced additional veins, obtuse or acute. Grain ellipsoid to subglobose, trigonous in section, ornamented, pericarp free. x = 9. Fl. and fr. Jul-Sep.[2] [more]

Eragrostis

flowers
Weeping Lovegrass (Eragrostis curvula)
Little Lovegrass (Eragrostis minor)
Eragrostis variabilis

Eragrostis (lovegrass) is genus of the Poaceae (grass family) and the namesake of the tribe Eragrostideae. It would remain therein as long as this group remains valid after revision of the Chloridoideae, even if other genera presently placed in the Eragrostideae are moved elsewhere. The name of the genus is derived from the Greek words e??? (eros), meaning "love," and a???st?? (agrostis), meaning "grass." [more]

Leptochloa

[more]

Lycurus

[more]

Muhlenbergia

Muhlenbergia is a genus of grass in the Poaceae family. There are around 160 species. They are native to temperate America and south Asia. Many species are known by the common name muhly. [more]

Saintpaulia

Saintpaulia, commonly known as African violet, is a genus of 6?20 species of herbaceous perennial flowering plants in the family Gesneriaceae, native to Tanzania and adjacent southeastern Kenya in eastern tropical Africa, with a concentration of species in the Nguru mountains of Tanzania. The genus is most closely related to Streptocarpus, with recent phylogenetic studies suggesting it has evolved directly from subgenus Streptocarpella. The common name was given due to a superficial resemblance to true violets (Viola, family Violaceae). Typically the African violet is a common household indoor plant but can also be an outdoor plant. [more]

Sporobolus

Sporobolus is a genus of grasses in the family Poaceae. They are usually called dropseed grasses or sacaton grasses. They are typical prairie and savanna plants, and they occur in other types of open habitat in warmer climates. [more]

Triodia

[more]

Tripogon

Perennials, often small. Culms densely tufted, slender, unbranched. Leaf blades mainly basal, filiform to setaceous, usually involute; ligule a narrow membrane fringed with hairs. Inflorescence a solitary unilateral terminal raceme. Spikelets subsessile, biseriate, broadside to rachis, linear to elliptic, laterally compressed, florets 2 to several, rachilla disarticulating above glumes and between florets; glumes narrow, shorter than lemmas or upper glume exceeding lowest lemma, unequal, membranous, 1-veined or upper glume sometimes 3-veined, keeled, acute to emarginate and mucronate, lower glume often with a lobe or tooth on one side; lemmas lanceolate to ovate, membranous, 3-veined, glabrous, lightly keeled or rounded, 2-dentate, midvein produced into an awn, teeth usually also mucronate or awned; palea keels scabrid or ciliolate, often winged. Floret callus bearded. Stamens 1-3. Caryopsis narrow, trigonous to subterete.[3] [more]

Uniola

Uniola is a genus of in the Poaceae family. It contains the following species: [more]

At least 45 species and subspecies belong to the Genus Uniola.
