Sandpaper Oak
''Quercus pungens'', commonly known as the sandpaper oak or scrub oak, is a North American species evergreen or sub-evergreen shrub or small tree in the white oak group. There is one recognised variety, ''Quercus pungens var. vaseyana'', the Vasey shin oak. Sandpaper oak hybridizes with gray oak (''Quercus grisea'') in the Guadalupe Mountains of New Mexico and Texas. Description The sandpaper oak can be a small tree of up to high or a large shrub that forms thickets. The bark is light brown and papery. The twigs are gray, with short velvety hairs, becoming smooth with age. The buds are dark red-brown, sparsely covered with hairs. The leathery leaves are semi-evergreen, being bright glossy green at first but turning darker with age. It is their rough texture, caused by minute persistent hair bases, that gives the tree its name of sandpaper oak. The inflorescence, which appears in spring, is reddish, the female catkins having one to three flowers and the male catkins numerous flow ...

Frederik Michael Liebmann
Frederik Michael Liebmann (10 October 1813 – 29 October 1856) was a Danish botanist. Liebmann studied botany at the University of Copenhagen, although he never obtained a formal qualification. He went on study tours of Germany and Norway before becoming lecturer at the Danish Royal Veterinary School in 1837. In 1840 he travelled to Cuba and Mexico; on his return in 1845 he was appointed Professor of Botany at the University of Copenhagen. He became Director of the university's Botanical Garden in 1852, a post he held until his death four years later. He was the editor of Flora Danica and issued fasc. 41-43 (1845–1852) and Supplement vol. 1, a total of 240 plates.

Chihuahua (state)
Chihuahua (), officially the Free and Sovereign State of Chihuahua ( es, Estado Libre y Soberano de Chihuahua), is one of the 31 states which, along with Mexico City, comprise the 32 federal entities of Mexico. It is located in northwestern Mexico, and is bordered by the states of Sonora to the west, Sinaloa to the southwest, Durango to the south, and Coahuila to the east. To the north and northeast, it shares an extensive border with the U.S. adjacent to the U.S. states of New Mexico and Texas. Its capital city is Chihuahua City; the largest city is Ciudad Juárez. Although Chihuahua is primarily identified with its namesake, the Chihuahuan Desert, it has more forests than any other state in Mexico, aside from Durango. Due to its variant climate, the state has a large variety of fauna and flora. The state is mostly characterized by rugged mountainous terrain and wide river valleys. The Sierra Madre Occidental mountain range, part of the continental spine that also inc ... [...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.

Pinyon Pine
The pinyon or piñon pine group grows in southwestern North America, especially in New Mexico, Arizona, and Utah. The trees yield edible nuts, which are a staple food of Native Americans, and widely eaten as a snack and as an ingredient in New Mexican cuisine. The name comes from the Spanish ''pino piñonero'', a name used for both the American varieties and the stone pine common in Spain, which also produces edible nuts typical of Mediterranean cuisine. Harvesting techniques of the prehistoric American Indians are still used today to collect the pinyon seeds for personal use or for commercialization. The pinyon nut or seed is high in fats and calories. Pinyon wood, especially when burned, has a distinctive fragrance, making it a common wood to burn in chimeneas. Pinyon pine trees are also known to influence the soil in which they grow by increasing concentrations of both macronutrients and micronutrients. Some of the species are known to hybridize, the most notable ones being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juniper
Junipers are coniferous trees and shrubs in the genus ''Juniperus'' () of the cypress family Cupressaceae. Depending on the taxonomy, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, throughout parts of West Asia, western, Central Asia, central and South Asia, southern Asia, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of in southeastern Tibet and the northern Himalayas, creating one of the highest tree lines on earth. Description Junipers vary in size and shape from tall trees, tall, to columnar or low-spreading shrubs with long, trailing branches. They are evergreen with needle-like and/or scale-like leaves.

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Chaparral
Chaparral ( ) is a shrubland plant community and geographical feature found primarily in the U.S. state of California, in southern Oregon, and in the northern portion of the Baja California Peninsula in Mexico. It is shaped by a Mediterranean climate (mild wet winters and hot dry summers) and infrequent, high-intensity crown fires. Chaparral features summer-drought-tolerant plants with hard sclerophyllous evergreen leaves, as contrasted with the associated soft-leaved, drought-deciduous, scrub community of coastal sage scrub, found often on drier, southern facing slopes within the chaparral biome. Three other closely related chaparral shrubland systems occur in central Arizona, western Texas, and along the eastern side of central Mexico's mountain chains (mexical), all having summer rains in contrast to the Mediterranean climate of other chaparral formations. Chaparral comprises 9% of California's wildland vegetation and contains 20% of its plant species. The name comes from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
