Samuel Botsford Buckley
Samuel Botsford Buckley (May 9, 1809 – February 18, 1884) was an American botanist, geologist, and naturalist. Buckley was born in Torrey, New York, on May 9, 1809. He graduated from Wesleyan University in 1836. He received a Ph.D. from Waco University in 1872. Buckley investigated the botany of the southern United States and discovered many new species of plants and mollusks. The plant genus '' Buckleya'' was named in his honor. Buckley determined the height of several summits in the Great Smoky Mountains, including Mount Buckley which was named in his honor. Buckley served as an assistant to Texas chief geologist Benjamin Franklin Shumard. He named an oak species after Shumard in 1860, but then stymied Shumard's reappointment under newly-elected Governor Sam Houston. Buckley was the Texas state geologist from 1860 to 1861 and 1874 to 1877. He was the scientific editor of the ''State Gazette'' in Austin, Texas Austin ( ) is the List of capitals in the United S ...

Flora Of Oklahoma
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. 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) wa ...

Trees Of Northern America
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, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide 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 trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus
An oak is a hardwood tree or shrub in the genus ''Quercus'' of the beech family. They have spirally arranged leaves, often with lobed edges, and a nut called an acorn, borne within a cup. The genus is widely distributed in the Northern Hemisphere; it includes some 500 species, both deciduous and evergreen. Fossil oaks date back to the Middle Eocene. Molecular phylogeny shows that the genus is divided into Old World and New World clades, but many oak species hybridise freely, making the genus's history difficult to resolve. Ecologically, oaks are keystone species in habitats from Mediterranean semi-desert to subtropical rainforest. They live in association with many kinds of fungi including truffles. Oaks support more than 950 species of caterpillar, many kinds of gall wasp which form distinctive galls (roundish woody lumps such as the oak apple), and a large number of pests and diseases. Oak leaves and acorns contain enough tannin to be toxic to cattle, but pigs are ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 southern live oaks section of the genus ''Quercus'' ( section ''Virentes''). It is distinguished from ''Quercus virginiana'' (southern live oak) most easily by the acorn The acorn is the nut (fruit), nut of the oaks and their close relatives (genera ''Quercus'', ''Notholithocarpus'' and ''Lithocarpus'', in the family Fagaceae). It usually contains a seedling surrounded by two cotyledons (seedling leaves), en ...s, which are slightly larger and with a more pointed apex. It is also a smaller tree, not exceeding in trunk diameterco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diospyros Texana
''Diospyros texana'' is a species of persimmon that is native to central, south and west Texas and southwest Oklahoma in the United States, and eastern Chihuahua, Coahuila, Nuevo León, and Tamaulipas in northeastern Mexico. Common names include Texas persimmon, Mexican persimmon and the more ambiguous " black persimmon". It is known in Spanish as chapote, chapote manzano, or chapote prieto, all of which are derived from the Nahuatl word '' tzapotl''. That word also refers to several other fruit-bearing trees.

Ungnadia Speciosa
''Ungnadia'' is a genus of flowering plants in the family Sapindaceae, containing one species, ''Ungnadia speciosa'', commonly known as the Mexican buckeye. It is native to northern Mexico, as well as Texas and southern New Mexico in the United States. The name honors Austrian ambassador Baron David Ungnad von Sonnegg, son of Andreas Ungnad von Sonnegg, who brought the horse chestnut (''Aesculus hippocastanum'') 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.

Opuntia Phaeacantha
''Opuntia phaeacantha'' is a species of prickly pear cactus known by the common names brown-spine prickly pear, tulip prickly pear, and desert prickly pear, which is 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 may hybridize 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, yellowish, or gray, usually darker brownish toward the base than the tip, and often over 3 cm in length. At the base of the spine cluster is a round tuft of easily detached yellowish to reddish or 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 ... [...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 ...
