Poa
''Poa'' is a genus of about 570 species of Poaceae, grasses, native to the temperate regions of both hemispheres. Common names include meadow-grass (mainly in Europe and Asia), bluegrass (mainly in North America), tussock (some New Zealand species), and speargrass. ''Poa'' () is Greek language, Greek for 'fodder'. ''Poa'' are members of the subfamily Pooideae of the family Poaceae. Bluegrass, which has green leaves, derives its name from the seed heads, which are blue when the plant is allowed to grow to its natural height of two to three feet (0.6 to 0.9 meters). The genus ''Poa'' includes both annual plant, annual and perennial plant, perennial species. Most are plant sexuality, monoecious, but a few are plant sexuality, dioecious (separate male and female plants). The leaf, leaves are narrow, folded or flat, sometimes bristled, and with the basal sheath flattened or sometimes thickened, with a blunt or hooded apex and membranaceous ligule.

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] |

Poa Annua
''Poa annua'', or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass originated as a hybrid between '' Poa supina'' and '' Poa infirma''. Major chromosomal rearrangements after polyploidy have contributed to variation in genome size in ''Poa annua''. Description It has a slightly creeping, fibrous, rootstock. The stem grows from 15–25 cm (6-10 in.) high. It is slightly flattened, due to being folded rather than rolled. The panicle is open and triangular shaped, 5 to 7.5 cm (2 to 3 in.) long. The spikelets are stalked, awnless, 1 to 2 cm (3/8 to 3/4 in.) long when flowering, and loosely arranged on delicate paired or spreading branches. Sometimes they are tinged purple. The vivid green leaves are short and blunt at the tips, shaped like the prow of a small canoe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poa Alpina
''Poa alpina'', commonly known as alpine meadow-grass or alpine bluegrass, is a species of grass with a primarily holarctic distribution. It is noted for being pseudoviviparous: in place of seeds, it sometimes reproduces asexually, creating new plantlets in the spikelets. References alpina Alpina Burkard Bovensiepen GmbH & Co.

Poa Arida
''Poa arida'' is a species of grass known by the common names plains bluegrass and prairie speargrass. It is native to North America, where it occurs throughout western and central Canada and the central United States.

Poa Atropurpurea
''Poa atropurpurea'' is a rare species of grass known by the common name San Bernardino bluegrass. It is endemic to southern California, where it is known from two regions, the San Bernardino Mountains near Big Bear and the Laguna Mountains of San Diego County. Description It grows in wet mountain meadows. It is a rhizomatous perennial grass growing in small, loose tufts up to about half a meter tall. The firm, narrow leaves often have rolled or folded edges. It is a dioecious plant, with male and female individuals bearing different flower types. The inflorescence is somewhat lance-shaped, with branches appressed, spreading upwards along the stem axis. Male and female inflorescences look similar. They may hold up to 70 spikelets each, which are purplish in color. Habitat In the San Bernardino Mountains the grass occurs in the pebble plain habitat near Big Bear with other rare plant species.USFWSFinal rule to determine endangered or threatened status for six plants from the mount ...

Poa Alpigena
''Poa alpigena'' is a species of grass occurring in mountainous regions. Its specific epithet "''alpigena''" means "growing in the alpine". Description ''Poa alpigena'' grows up to tall, with firm leaf blades. Its panicle grows up to high, with its lax branches sometimes reflexed. Its crowded spikelets are long. Its glumes are lance-ovate, with the second glume sometime reaching to the middle of the lemma above it. The nerves of the glumes range from glabrous to scabrous, and the lemmas are minutely pubescent. ''Poa alpigena'' has a similar habit to ''Poa arida'', only taller. The most distinguishing characteristic of ''P. alpigena'' is its curved underground stem. The grass flowers from June to August. Distribution and habitat ''Poa alpigena'' occurs in alpine meadows, wet slopes, bogs, and other similar wet areas. It can be found from Greenland and Labrador Labrador () is a geographic and cultural region within the Canadian province of Newfoundland and Labrador. It is ...

Poa Arctica
''Poa arctica'', the Arctic bluegrass or Arctic meadow grass, is a species of flowering plant in the family Poaceae, with a subarctic circumpolar distribution, extending into the Rockies. Often a dominant species in the tundra In physical geography, a tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: #Arctic, Arctic, Alpine tundra, Alpine, and #Antarctic ..., it responds positively to disturbance.

Poa Bolanderi
''Poa bolanderi'' is a species of grass known by the common name Bolander's bluegrass. It is native to western North America from British Columbia to Utah to California, where it is a resident of mountain habitat, particularly pine and fir forests. It is an annual grass growing in clumps up to 60 centimeters tall. The inflorescence occupies the top 10 to 15 centimeters of the stem. It is narrow in flower, with branches appressed, growing parallel to the stem. As the fruit develops the branches spread out, becoming perpendicular to the stem, nodding, or drooping. The branches have few, sparse spikelets. Poa bolanderi commemorates Henry Nicholas Bolander, who collected the type specimen in present-day Yosemite National Park Yosemite National Park ( ) is a List of national parks of the United States, national park of the United States in California. It is bordered on the southeast by Sierra National Forest and on the northwest by Stanislaus National Forest. The p ... in ...
