Flora Of Oklahoma
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Coahuila
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quercus
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably '' Lithocarpus'' (stone oaks), as well as in those of unrelated species such as ''Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. ...

Quercus Fusiformis
''Quercus fusiformis'' (also often referred to as ''Q. virginiana'' var. ''fusiformis''), commonly known as escarpment live oak, plateau live oak, plateau oak, or Texas live oak, is an evergreen or nearly evergreen tree. Its native range includes the Quartz Mountains and Wichita Mountains in southwestern Oklahoma, through Texas, to the Mexican states of Coahuila, Tamaulipas, and Nuevo León. ''Quercus fusiformis'' is an evergreen tree in the white oak section of the genus ''Quercus''. It is distinguished from ''Quercus virginiana'' (southern live oak) most easily by the acorns, which are slightly larger and with a more pointed apex. It is also a smaller tree, not exceeding in trunk diametercompared to 2.5 m (75 in) in diameter in southern live oakwith more erect branching and a less wide crown. Like ''Q. virginiana'', its magnificent, stately form and unparalleled longevity has endeared it to generations of residents throughout its native range. Its low hanging branches ...

Ungnadia Speciosa
''Ungnadia'' is a genus of flowering plants in the family Sapindaceae containing one species, ''Ungnadia speciosa'', the Mexican buckeye. It is native to northern Mexico, as well as Texas and southern New Mexico in the United States. The name honours Austrian ambassador Baron David von Ungnad, who brought the horse chestnut to Vienna in 1576, introducing the plant into western Europe. It differs from the buckeyes in the related genus ''Aesculus'' but the seeds and nuts are similar. Another similar related genus is the soapberry (genus ''Sapindus''). ''Ungnadia'' seeds are poisonous despite their sweetness, and sometimes used as marbles. The foliage is toxic and rarely browsed by livestock, but bees produce honey from the floral nectar. Description ''Ungnadia speciosa'' a deciduous shrub or small tree (< 25 ft) that is often multi trunked. The |
Opuntia Phaeacantha
''Opuntia phaeacantha'' is a species of prickly pear cactus known by the common names tulip prickly pear, Mojave prickly pear, and desert prickly pear found across the southwestern United States, lower Great Plains, and northern Mexico. The plant forms dense but localized thickets. Several varieties of this particular species occur, and it also hybridizes easily with other prickly pears, making identification sometimes tricky. Description ''Opuntia phaeacantha'' has a mounding habit of flattened green pads. The pads are protected by clusters of spines. Each cluster bearing 1-4 spines. The spines are brown, reddish-brown, or gray, and often over 3 cm in length. At the base of the spine cluster is a round tuft of easily detached brown bristles called Glochids. Glochids are also present on the fruit. This is the source for the plants common name "prickly pear". The flowers are bright yellow with a pale green center. Some plants produce yellow flowers with an orange-red center. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opuntia Imbricata
''Cylindropuntia imbricata'', the cane cholla (walking stick cholla, tree cholla, or chainlink cactus), is a cactus found in the Southwestern United States and northern Mexico, including some cooler regions in comparison to many other cacti. It occurs primarily in the arid regions of the Southwestern United States in the states of Kansas, Oklahoma, Texas, New Mexico, Arizona, Colorado, and Nevada. It is often conspicuous because of its shrubby or even tree-like size, its silhouette, and its long-lasting yellowish fruits. Distribution and habitat The cane cholla's range is the arid regions of Nevada, Arizona, New Mexico, Colorado, Oklahoma, Kansas, and Texas, south to Durango, Zacatecas, and San Luis Potosí. It occurs at altitudes from and is hardy for a cactus (USDA Zone 5A). In parts of its range, often just below the pinyon-juniper belt, it can be abundant, surrounded by low grasses and forbs that are brown most of the year; in such places chollas are conspicuous as the only ...
