Stipeae
The Stipeae are a tribe of grasses within the subfamily Pooidae, with up to 600 described species. Description The defining morphological features of the Stipeae include single-flowered spikelets lacking a rachilla extension, and the lemmas (the external bract) have either a sharp point or a terminal awn (long bristle). Genera The tribe includes 28 genera: Many species initially placed into ''Stipa'' have now been split off into new genera. Some recent papers have analysed relationships within and between the genera, but a complete analysis has not yet been performed. Stipoid grasses use the C3 photosynthetic pathway and live in temperate areas worldwide. Known fossils date from the late Miocene The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recen .... References External li ...

Patis (plant)
''Patis'' is a genus of grasses in the Stipeae tribe of the grass family, found in China, Korea, Japan, eastern Canada, and north central and eastern United States. The name ''Patis'', an anagram of the closely related ''Stipa'', was assigned by Japanese botanist Jisaburo Ohwi (1905–1977) in 1942. Species Three species are recognized; each of them has a synonym. In each case, the alternative genus name is within the tribe Stipeae The Stipeae are a tribe of grasses within the subfamily Pooidae, with up to 600 described species.

Stipa
''Stipa'' is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to ''Stipa'', which have since been reclassified into new genera. Many species are important forage crops. Several species such as ''Stipa brachytricha'', ''S. arundinacea'', ''S. splendens'', ''S. calamagrostis'', ''S. gigantea'' and ''S. pulchra'' are used as ornamental plants. One former species, esparto grass (''Macrochloa tenacissima''), is used for crafts and extensively in paper making. It is a coarse grass with inrolled leaves and a panicle patterned inflorescence. Ecology Species of the genus ''Stipa'' can occur in grasslands or in savanna habitats. Certain specific prairie plant associations are dominated by grasses of the genus ''Stipa'', which genus often lends its name to the terminology of some prairie types. ...

Nassella
''Nassella'', or needlegrass, is a New World genus of over 100 perennial bunchgrasses found from North America through South America. The Latin word ''nassa'' refers to "a basket with a narrow neck". It is usually considered segregate from the genus ''Stipa'' and includes many New World species formerly classified in that genus. As of 2011, ''The Jepson Manual'' includes ''Nassella'' within ''Stipa''. ''Nasella'' is characterized by strongly overlapping lemma margins and reduced, veinless paleae. The lemma tips are fused into the "crown", a short membrane that surrounds the base of the lemma. The rim of the crown usually has hairs. Many species form both cross-pollinating and self-pollinating florets in the terminal panicle. The self-pollinating florets have 1–3 small anthers; the cross-pollinating florets have 3 longer anthers. Some species have self-pollinating inflorescences hidden in their basal leaf sheaths. These hidden inflorescences lack glumes and usually lack awn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
