Asphodelaceae

Belongs within: Petrosaviidae.Contains: Bulbine, Alooideae. The Asphodelaceae are a group of monocotyledons found in warmer regions of the Old World, characterised by the possession of hemitropous ovules and arillate seeds (Eggli & Nyffeler 2020). They have been divided between the succulent Alooideae and the largely non-succulent Asphodeloideae but the latter have been found to be… Continue reading Asphodelaceae

Commelinidae

Belongs within: Petrosaviidae.Contains: Poales, Commelinales, Zingiberales, Arecaceae. The Commelinidae are a clade of monocotyledons united by the presence of UV-fluorescent ferulic acid in the cell walls. Many members of the clade also have bracteate inflorescences, starchy pollen and endosperm, and silica bodies in the plant (Cantino et al. 2007). The Dasypogonaceae are an Australian family… Continue reading Commelinidae

Belongs within: Poaceae. Urochloa, signalgrass, is a tropical genus of coarse and weedy grasses. Browntop millet U. ramosa is cultivated in southern Asia as a cereal crop. Characters (from Flora of China): Annuals or perennials, often coarse and weedy. Leaf blades linear to broadly lanceolate; ligule a ciliate membrane. Inflorescence composed of racemes along a… Continue reading Urochloa

Ehrhartoideae

Belongs within: Poaceae. The Ehrhartoideae are a clade of grasses supported primarily by molecular data, characterised by the presence of one female-fertile floret per spikelet (Grass Phylogeny Working Group 2001). The most economically significant member of the clade is undoubtedly Oryza sativa, the rice plant, widely grown around the world. Wild rice species of the… Continue reading Ehrhartoideae

Andropogoneae

Belongs within: Panicoideae.Contains: Sorghum, Dichanthium, Saccharum, Ischaemum, Andropogon, Chrysopogon, Cymbopogon, Schizachyrium. The Andropogoneae are a tribe of C4 grasses characterised by the possession of paired spikelets with bracts present outside the spikelets (Grass Phylogeny Working Group 2001). This tribe includes a number of economically significant crops. Miscanthus species are grown as ornamentals and for biofuel.… Continue reading Andropogoneae

Eriachneae

Belongs within: Poaceae. The Eriachneae are an Indo-Australian group of grasses bearing bisexual florets and hairy lemmas. They include the genera Eriachne and Pheidochloa, with glumes being more or less equal in length in Eriachne but with the upper glume being twice the length of the lower in Pheidochloa. Characters (from Flora of China): Annuals… Continue reading Eriachneae

Cyperaceae

Belongs within: Poales.Contains: Kobresia, Chrysitricheae, Hypolytreae, Bisboeckelereae, Scleria, Cryptangieae, Schoeneae, Carpheae, Rhynchospora, Scirpeae, Eleocharis, Abildgaardieae, Fuireneae. The Cyperaceae, sedges, are a cosmopolitan group of grass-like plants commonly found in damp, open habitats. Phylogenetic analysis supports a basal division between the subfamilies Mapanioideae and Cyperoideae. Members of the Mapanioideae produce flowers in a ‘pseudanthium’ that is… Continue reading Cyperaceae
