Yellow-nosed Cotton Rat
The yellow-nosed cotton rat (''Sigmodon ochrognathus'') is a species of rodent in the family Cricetidae. It is native to Mexico and to the states of Arizona, New Mexico, and Texas in the United States, where it inhabits mountain grassland, scrub, and pinyon-juniper woodland. It is common over much of its wide range and the IUCN considers it to be of " least concern". Description In captivity, male yellow-nosed cotton rats grow to a maximum head and body length of about with females being slightly shorter and heavier. No significant sexual dimorphism has been noted in the wild. The head is short and broad and the tail is hairy, with many small scales no more than wide. The fur on the head, back, and sides is a dull gray color, apart from the snout and a ring round the eye which are ochre, features that distinguish this species from other members of the genus '' Sigmodon''. The underparts are grayish-white, the feet grayish-buff, the upper side of the tail blackish and the un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vernon Orlando Bailey
Vernon Orlando Bailey (1864–1942) was an American naturalist who specialized in mammalogy. He was employed by the Bureau of Biological Survey, United States Department of Agriculture (USDA). His contributions to the Bureau of Biological Survey numbered roughly 13,000 specimens including many new species. Bailey published 244 monographs and articles during his career with the USDA, and is best known for his biological surveys of Texas, New Mexico, North Dakota, and Oregon. Life and work The fourth child of Emily and Hiram Bailey, Vernon Orlando Bailey was born on June 21, 1864 in Manchester, Michigan. Bailey and his pioneer family moved by horse-drawn wagon to Elk River, Minnesota in 1870. Hiram Bailey was a woodsman and a mason by trade that taught his son how to hunt at an early age. Since there was no school in the frontier town at the time, the Baileys schooled their children at home until they and several other local families established a school in 1873. Vernon briefly at ...

Douglas Fir
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 old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dasylirion Wheeleri
''Dasylirion wheeleri'' (desert spoon, spoon flower, sotol, or common sotol) is a species of flowering plant in the asparagus family (Asparagaceae), native to arid environments of northern Mexico and the southwestern United States. Description ''Dasylirion wheeleri'' is a moderate to slow-growing evergreen shrub with a single unbranched trunk up to thick growing to tall, though often recumbent on the ground. The leaf blade is slender, long, gray-green, with a toothed margin. The leaves radiate from the center of the plant's apex in all directions (spherical). Blooming from May to July, the flowering stem grows above the foliage, to a height of tall and a diameter of . The stem is topped by a long plume of straw-colored small flowers about 2.5 cm long with six tepals. The color of the flower helps determine the gender of the plant, being mostly white for males and purple-pink for females. The fruit is an oval dry capsule long, containing a single seed.

Opuntia
''Opuntia'', commonly called prickly pear or pear cactus, is a genus of flowering plants in the cactus family Cactaceae. Prickly pears are also known as ''tuna'' (fruit), ''sabra'', ''nopal'' (paddle, plural ''nopales'') from the Nahuatl word for the pads, or nostle, from the Nahuatl word for the fruit; or paddle cactus. The genus is named for the Ancient Greek city of Opus, where, according to Theophrastus, an edible plant grew and could be propagated by rooting its leaves. The most common culinary species is the Indian fig opuntia (''O. ficus-indica''). Description ''O. ficus-indica'' is a large, trunk-forming, segmented cactus that may grow to with a crown of over in diameter and a trunk diameter of . Cladodes (large pads) are green to blue-green, bearing few spines up to or may be spineless. Prickly pears typically grow with flat, rounded cladodes (also called platyclades) containing large, smooth, fixed spines and small, hairlike prickles called glochids that ...

Sugar Sumac
''Rhus ovata'', commonly known as sugar bush or sugar sumac, is a shrub or small tree found growing in the canyons and slopes of the chaparral and related ecosystems in Southern California, Arizona, Baja California and Baja California Sur. It is a long lived-plant, up to 100 years, and has dense evergreen foliage that make it conspicuous. It is closely related to and hybridizes with the lemonade sumac. Description Morphology This plant is a tall, wide woody shrub to small tree that ranges in height from with a rounded appearance. The stout twigs are thick and reddish when young. The foliage is suspended on a petiole 10–30 mm long.

Mimosa
''Mimosa'' is a genus of about 590 species of herbs and shrubs, in the mimosoid clade of the legume family Fabaceae. The generic name is derived from the Greek word (''mimos''), an "actor" or "mime", and the feminine suffix -''osa'', "resembling", suggesting its 'sensitive leaves' which seem to 'mimic conscious life'. Two species in the genus are especially notable. One is ''Mimosa pudica'', commonly known as touch-me-not, which folds its leaves when touched or exposed to heat. It is native to southern Central and South America but is widely cultivated elsewhere for its curiosity value, both as a houseplant in temperate areas, and outdoors in the tropics. Outdoor cultivation has led to weedy invasion in some areas, notably Hawaii. The other is ''Mimosa tenuiflora'', which is best known for its use in shamanic ayahuasca brews due to the psychedelic drug dimethyltryptamine found in its root bark. Taxonomy The taxonomy of the genus ''Mimosa'' has gone through several periods of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agave
''Agave'' (; ; ) is a genus of monocots native to the hot and arid regions of the Americas and the Caribbean, although some ''Agave'' species are also native to tropical areas of North America, such as Mexico. The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves. ''Agave'' now includes species formerly placed in a number of other genera, such as ''Manfreda'', ×''Mangave'', ''Polianthes'' and ''Prochnyanthes''. Many plants in this genus may be considered perennial, because they require several to many years to mature and flower. However, most ''Agave'' species are more accurately described as monocarpic rosettes or multiannuals, since each individual rosette flowers only once and then dies; a small number of ''Agave'' species are polycarpic. Maguey flowers are considered edible in many indigenous culinary traditions of Mesoamerica. Along with plants from the closely related genera ''Yucca'', ''Hes ...

Yucca
''Yucca'' is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae. Its 40–50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers. They are native to the hot and dry (arid) parts of the Americas and the Caribbean. Early reports of the species were confused with the cassava (''Manihot esculenta''). Consequently, Linnaeus mistakenly derived the generic name from the Taíno word for the latter, ''yuca''. The Aztecs living in Mexico since before the Spanish arrival, in Nahuatl, call the local yucca species (''Yucca gigantea'') , which gave the Spanish . is also used for ''Yucca filifera''. Distribution The natural distribution range of the genus ''Yucca'' (49 species and 24 subspecies) covers a vast area of the Americas. The genus is represented throughout Mexico and extends into Guatemala (''Yucca guatemalensis''). It also extends to the north through Baja Cali ...
