Viola Guadalupensis
''Viola guadalupensis'', the Guadalupe Mountains violet, is a perennial yellow-flowered violet, and is an extremely rare endemic plant of the Guadalupe Mountains. The violet is known only from Guadalupe Mountains National Park, where it grows at high elevations on vertical limestone faces. The Guadalupe Mountains violet was first described in 1990 when it was found at one location along the East Rim of Frijole Ridge. A second, isolated population was found in 2006 in a steep, slot-canyon drainage about 2 km from the first colony, and two additional populations of the violet were found in the park in 2009. The Guadalupe Mountains violet is currently considered a National Park Service Species of Concern. The species is thought to have highly specific habitat requirements. It is the only yellow-flowered violet in the region. Status and trends At the plant’s type locality (the location where the plant was first found and described), the Guadalupe Mountains violet grows in mats of u ...

Guadalupe Mountains
The Guadalupe Mountains ( es, Sierra de Guadalupe) are a mountain range located in West Texas and southeastern New Mexico. The range includes the highest summit in Texas, Guadalupe Peak, , and the "signature peak" of West Texas, El Capitan, both of which are located within Guadalupe Mountains National Park. The Guadalupe Mountains are bordered by the Pecos River valley and Llano Estacado to the east and north, Delaware Mountains to the south, and Sacramento Mountains to the west. One of the clearest exposures of a prehistoric reef is preserved in the mountain range's bedrock geology. Bedrock contains fossils of reef-dwelling organisms from the Permian period, and the geology is widely studied, mostly by stratigraphers, paleontologists, and Paleoecologists (see geology section). History Archaeological evidence has shown that people lived over 10,000 years ago in and among the many caves and alcoves. The first humans to live here were hunter-gatherers who followed large game ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guadalupe Mountains National Park
Guadalupe Mountains National Park is an American national park in the Guadalupe Mountains, east of El Paso, Texas. The mountain range includes Guadalupe Peak, the highest point in Texas at , and El Capitan used as a landmark by travelers on the route later followed by the Butterfield Overland Mail stagecoach line. The ruins of a stagecoach station stand near the Pine Springs visitor center. The restored Frijole Ranch contains a small museum of local history and is the trailhead for Smith Spring. The park covers in the same mountain range as Carlsbad Caverns National Park, about to the north in New Mexico. The Guadalupe Peak Trail winds through pinyon pine and Douglas-fir forests as it ascends over to the summit of Guadalupe Peak, with views of El Capitan and the Chihuahuan Desert. The McKittrick Canyon trail leads to a stone cabin built in the early 1930s as the vacation home of Wallace Pratt, a petroleum geologist who donated the land.

Pseudotsuga Menziesii
The Douglas fir (''Pseudotsuga menziesii'') is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir (''P. menziesii'' var. ''menziesii''), Rocky Mountain Douglas-fir (''P. menziesii'' var. ''glauca'') and Mexican Douglas-fir (''P. menziesii'' var. ''lindleyana''). Despite its common names, it is not a true fir (genus ''Abies''), spruce (genus ''Picea''), or pine (genus ''Pinus''). It is also not a hemlock; the genus name ''Pseudotsuga'' means "false hemlock". Description Douglas-firs are medium-size to extremely large evergreen trees, tall (although only ''Pseudotsuga menziesii var. menziesii'', common name coast Douglas-firs, reach heights near 100 m) and commonly reach in diameter, although trees with diameters of almost exist. The largest coast Douglas-firs regularly live over 500 years, with the oldes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Range and Habitat ''Petrophytum caespitosum'' is native to the Western United States where it grows in mountainous areas from the Sierra Nevada to the Rocky Mountains. It grows among limestone rocks in forested and woodland habitat and on open limestone bluffs and cliffs. Description ''Petrophytum caespitosum'' is a very low matted shrub growing in carpets up to 80 centimeters wide, creeping over rocks. The plant often grows on vertical surfaces and hangs by its roots, which cling to cracks in rock. The stems are thick and very short, covered densely in rosettes of oval leaves. Both surfaces of the leaves are lightly covered in short fine hairs, which may not be obvious without close inspection. It produces many inflorescences which are spikelike clusters of flowers arising on e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valeriana Texana
''Valeriana'' is a genus of flowering plants in the family Caprifoliaceae, members of which may by commonly known as valerians. It contains many species, including the garden valerian, ''Valeriana officinalis''. Species are native to all continents except Antarctica, with centers of diversity in Eurasia and South America (especially in the Andes). Fossil record Fossil seeds of ''Valeriana sp,'' among them †''Valeriana pliocenica'', have been recovered from Late Miocene deposits of southern Ukraine, from Pliocene deposits of south-eastern Belarus and Bashkortostan in central Russia. The fossil seeds are most similar to the extant European ''Valeriana simplicifolia''. Species , Plants of the World Online accepts over 420 species and hybrids, including: *''Valeriana alypifolia'' *''Valeriana aretioides'' *''Valeriana asterothrix'' *''Valeriana bertiscea'' *''Valeriana buxifolia'' *''Valeriana californica'' *''Valeriana celtica'' (Alpine valerian or valerian spikenard) *''Valeria ...

Herbivory
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material. A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This flora is made up of cellulose-digesting protozoans or bacteria. Etymology Herbivore is the anglicized form of a modern Latin coinage, ''herbivora'', cited in Charles Lyell's 1830 ''Principles of Geology''.J.A. Simpson and E.S.C. Weiner, eds. (2000) ''The Oxford English Dictionary'', vol. 8, p. 155. Richard Owen employed the anglicized term in an 1854 work on fossil teeth and skeletons. ''Herbivora'' is derived from Latin ''herba ...

Viola (plant)
''Viola'' is a genus of flowering plants in the violet family Violaceae. It is the largest genus in the family, containing between 525 and 600 species. Most species are found in the temperate Northern Hemisphere; however, some are also found in widely divergent areas such as Hawaii, Australasia, and the Andes. Some ''Viola'' species are perennial plants, some are annual plants, and a few are small shrubs. Many species, varieties and cultivars are grown in gardens for their ornamental flowers. In horticulture the term pansy is normally used for those multi-colored, large-flowered cultivars which are raised annually or biennially from seed and used extensively in bedding. The terms viola and violet are normally reserved for small-flowered annuals or perennials, including the wild species. Description Annual or perennial caulescent or acaulescent (with or without a visible plant stem above the ground) herbs, shrubs or very rarely treelets. In acaulescent taxa the foliage and flower ...
