Paspaleae
Paspaleae is a tribe of the Panicoideae subfamily in the grasses (Poaceae), native mainly to the tropical and subtropical Americas but with a number of species introduced to other regions. It includes roughly 680 species in 39 genera. Species in this tribe use either of the C3 or C4 photosynthetic pathways. The genera of Paspaleae used to be included in the Paniceae but were assigned to a new tribe following molecular phylogenetic analyses in 2012. The Paspaleae have an ancestral number of chromosomes ( monoploid number) of ''x'' = 10, unlike the Paniceae ''sensu stricto'' with ''x'' = 9, and are more closely related to the tribes Andropogoneae and Arundinelleae. The tribe is subdivided into three subtribes, with one genus, '' Reynaudia'', unplaced (''incertae sedis'') and probably basal to the other genera. The genus ''Lecomtella ''Lecomtella'' is a genus of grasses with the sole species ''Lecomtella madagascariensis'', native to Madagascar. It is the only genus in the ...

Panicoideae
Panicoideae is the second-largest subfamily of the grasses with over 3,500 species, mainly distributed in warm temperate and tropical regions. It comprises some important agricultural crops, including sugarcane, maize (or corn), sorghum, and switchgrass. C4 photosynthesis evolved independently a number of times in the subfamily, which presumably had a C3 ancestor. Description The ligule has a fringe of hairs. The inflorescence is branched around a common axis. The spikelets are all alike with two bisexual florets that are joined below the glumes (the outer floral envelopes). The lower glume is shorter than the spikelet. Systematics and taxonomy Within the PACMAD clade of grasses, the Panicoideae are sister to a clade made of the four subfamilies Arundinoideae, Chloridoideae, Danthonioideae, and Micrairoideae. A modern phylogenetic classification divides the Panicoideae in twelve tribes corresponding to monophyletic clades; two genera, '' Chandrasekharania'' and ''Jansenella ...

Paniceae
Paniceae is a large tribe of the subfamily Panicoideae in the grasses (Poaceae), the only in the monotypic supertribe Panicodae. It includes roughly 1,500 species in 84 genera, primarily found in tropical and subtropical regions of the world. Paniceae includes species using either of the C4 and C3 photosynthetic pathways, as well as presumably intermediate species. Most of the millets are members of tribe Paniceae. The tribe is subdivided into seven subtribes, but some genera are as yet unplaced (''incertae sedis''). Species in the Paniceae have an ancestral chromosome number ( monoploid number) of ''x'' = 9, while species with ''x'' = 10 formerly included are now recognised as separate tribe, Paspaleae.

Lecomtella
''Lecomtella'' is a genus of grasses with the sole species ''Lecomtella madagascariensis'', native to Madagascar. It is the only genus in the tribe Lecomtelleae. The species and genus were described by Aimée Antoinette Camus in 1925. ''L. madagascariensis'' is perennial, has culms long, and resembles bamboo, to which it is however unrelated. Contrarily to many other species in subfamily Panicoideae, this grass uses C3 photosynthesis. It is only found in the Andringitra Massif of central Madagascar, at elevations of , and critically endangered. The genus is included in the tribe Paspaleae Paspaleae is a tribe of the Panicoideae subfamily in the grasses (Poaceae), native mainly to the tropical and subtropical Americas but with a number of species introduced to other regions.

Paspalum Distichum
''Paspalum distichum'' is a species of grass. Common names include knotgrass, water finger-grass, couch paspalum, eternity grass, gingergrass, and Thompson grass. Its native range is obscure because it has long been present on most continents, and in most areas it is certainly an introduced species. Its native range probably includes parts of the tropical Americas. This is a perennial grass forming clumps and spreading via rhizomes and stolons. It grows decumbent or erect to a maximum height near 60 centimeters. The inflorescence is usually divided into two branches lined with spikelets. ''Paspalum distichum'' is a food source for several avian species, including the long-tailed widowbird The long-tailed widowbird (''Euplectes progne''), also known as the "sakabula", is a species of bird in the family Ploceidae.Mackworth-Praed, C.W., and C.H.

Incertae Sedis
' () or ''problematica'' is a term used for a taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty at specific taxonomic levels is indicated by ' (of uncertain family), ' (of uncertain suborder), ' (of uncertain order) and similar terms. Examples *The fossil plant '' Paradinandra suecica'' could not be assigned to any family, but was placed ''incertae sedis'' within the order Ericales when described in 2001. * The fossil ''Gluteus minimus'', described in 1975, could not be assigned to any known animal phylum. The genus is therefore ''incertae sedis'' within the kingdom Animalia. * While it was unclear to which order the New World vultures (family Cathartidae) should be assigned, they were placed in Aves ''incertae sedis''. It was later agreed to place them in a separate order, Cathartiformes. * Bocage's longbill, ''Motacilla bocagii' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
