Danthonioideae
Danthonioideae is a mainly southern hemisphere subfamily of grasses, containing the single tribe Danthonieae and one unplaced genus, with altogether roughly 300 species. It includes herbaceous to partially woody perennial or annual (less common) grasses that grow in open grasslands, shrublands, and woodlands. It belongs to the PACMAD clade of grasses, but unlike some other lineages in that clade, grasses in the Danthonioideae exclusively use the C3 photosynthetic pathway. Its sister group is the subfamily Chloridoideae. There are 19 genera, 18 of which are placed in tribe Danthonieae, while one is as yet unplaced (''incertae sedis''). The relationships within the group are complicated; conflicting phylogenetic evidence from nuclear and chloroplast DNA suggests that hybridisation events played an important role in the Danthonioideae. *''incertae sedis'': *: '' Danthonidium'' * tribe Danthonieae: *: '' Austroderia'', '' Capeochloa'', '' Chaetobromus'', '' Chimaerochloa'', '' Ch ...

PACMAD
The PACMAD clade (previously PACCMAD, PACCAD, or PACC) is one of two major lineages (or clades) of the true grasses (Poaceae), regrouping six subfamilies and about 5700 species, more than half of all true grasses. Its sister group is the BOP clade. The PACMAD lineage is the only group within the grasses in which the C4 photosynthesis pathway has evolved; studies have shown that this happened independently multiple times. Phylogeny The name of the clade comes from the first initials of the included subfamilies Panicoideae, Arundinoideae, Chloridoideae, Micrairoideae Micrairoideae is a subfamily of the grass family Poaceae, distributed in tropical and subtropical regions. Within the PACMAD clade, it is sister to subfamily Arundinoideae. It includes roughly 190 species in nine genera. A phylogenetic classifi ..., Aristidoideae, and Danthonioideae. It has no defined taxonomic rank but is used frequently because it refers to a well-defined monophyletic group with a distinc ...

Poaceae
Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, including staple foods from domesticated cereal crops such as maize, wheat, rice, oats, barley, and millet for people and as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials ( bamboo, thatch, and straw); oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chloridoideae
Chloridoideae is one of the largest subfamily, subfamilies of Poaceae, grasses, with roughly 150 genera and 1,600 species, mainly found in arid tropical or subtropical grasslands. Within the PACMAD clade, their sister group is the Danthonioideae. The subfamily includes widespread weeds such as Bermuda grass (''Cynodon dactylon''), goosegrass (''Eleusine indica'') or finger grass (''Chloris (plant), Chloris''), but also millet species grown in some tropical regions, namely finger millet (''Eleusine coracana'') and teff (''Eragrostis tef''). With the exception of some species in ''Ellisochloa'' and ''Eleusine indica'', most of the subfamily's species use the C4 carbon fixation, C4 photosynthetic pathway. The first evolutionary transition from C3 photosynthesis, C3 to C4 photosynthesis in the grasses probably occurred in this subfamily, around 32 to 25 million years ago in the Oligocene.

Cortaderia
''Cortaderia'' is a genus of plants in the Poaceae or grass family of plants. All current species included in the ''Cortaderia'' genus are native to South and Central America, ranging from the Patagonia region of southern Chile and Argentina, to Costa Rica. For many years, five species native to New Zealand were included in the genus, but since 2011 these have been since reclassified into the genus '' Austroderia'' containing only species native to New Zealand. Etymology The common name pampas grass, though strictly referring to ''C. selloana'', is frequently applied to all species in the genus, as well as the five former members reclassied into the genus Austroderia (sometimes also to species of '' Erianthus'' and '' Saccharum ravennae''). The name of the genus is derived from the Argentine Spanish word ''cortadera'', which in turn refers to the sharp serrations on the leaves. '' Cortaderia jubata'' and '' C. rudiuscula'' produce copious seed asexually. Description Cortaderi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cortaderia Selloana
''Cortaderia selloana'' is a species of flowering plant in the family Poaceae. It is referred to by the common name pampas grass, and is native to southern South America, including the Pampas region after which it is named. It is widely distributed throughout the world as a cultivated ornamental and invasive species. Etymology ''Cortaderia'' is derived from the Argentine Spanish name 'cortadera', meaning 'cutter', in reference to its razor sharp leaf margins.Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 122, 348 ''Selloana'' is named for Friedrich Sellow (1789–1831), a German botanist and naturalist from Potsdam who worked as a plant collector in Brazil. He studied the flora of South America, especially that of Brazil. The specific epithet ''selloana'' was given by Josef August and Julius Hermann Schultes in 1827.
