Senna Armata
''Senna armata'' is a species of flowering plant in the legume family known by the common names spiny senna and desert senna. It is native to the desert regions around the intersection of Nevada, Arizona, eastern California and northern Baja California, where it grows in sandy and rocky habitat, such as arroyos. It is a shrub growing up to a meter tall, its grooved, branching stems often narrowing to thorns at their tips. The spiny branches are coated in tubular hairs which help protect it from hot desert air.Rodgers, J. E''Senna armata''.Joshua Tree National Park. The spine-tipped leaves are each made up of two to four pairs of small leaflets. The leaves are ephemeral, dropping soon after emerging, leaving the shrub naked most of the time. Flowers occur singly or in small clusters in leaf axils. They are fragrant and showy, with five petals in shades of yellow to salmon pink Salmon is a range of pinkish- orange to light pink colors, named after the color of salmon flesh. T ...

Sereno Watson
Sereno Watson (December 1, 1826 in East Windsor Hill, Connecticut – March 9, 1892 in Cambridge, Massachusetts) was an American botanist. Graduating from Yale in 1847 in Biology, he drifted through various occupations until, in California, he joined the Clarence King Expedition and eventually became its expedition botanist. Appointed by Asa Gray as assistant in the Gray Herbarium of Harvard University in 1873, he later became its curator, a position he maintained until his death. Watson was elected a Fellow of the American Academy of Arts and Sciences in 1874, and a member of the National Academy of Sciences in 1889.

Arroyo (creek)
An arroyo (; from Spanish arroyo , "brook"), also called a wash, is a dry stream, creek, stream bed or gulch that temporarily or seasonally fills and flows after sufficient rain. Flash floods are common in arroyos following thunderstorms. ''Wadi'' (Arabic) is used in North Africa and Western Asia for similar landforms. The desert dry wash biome is restricted to the arroyos of the southwestern United States. Arroyos provide a water source to desert animals. Types and processes Arroyos can be natural fluvial landforms or constructed flood control channels. The term usually applies to a Grade (slope), sloped or mountainous terrain in xeric and desert climates. In addition: in many rural communities arroyos are also the principal transportation routes; and in many urban communities arroyos are also parks and recreational locations, often with linear multi-use bicycle, pedestrian, and equestrian trails. Flash flooding can cause the deep arroyos or deposition of sediment on flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmon Pink
Salmon is a range of pinkish-orange to light pink colors, named after the color of salmon flesh. The first recorded use of ''salmon'' as a color name in English was in 1776.Maerz and Paul ''A Dictionary of Color'' New York:1930 McGraw-Hill Page 203; Color Sample of Salmon: Page 43 Plate 10 Color Sample A7 The actual color of salmon flesh varies from almost white to light orange, depending on their levels of the carotenoid astaxanthin due to how rich a diet of krill and shrimp the fish feeds on; salmon raised on fish farms are given non-synthetic or artificial coloring in their food. __TOC__ Variations of salmon Light salmon resembles the color salmon, but is lighter, not to be confused with dark salmon, which resembles salmon pink but is darker. Salmon pink (or ''salmon'' in Crayola crayons) was introduced by Crayola in 1949. See the List of Crayola crayon colors. Dark salmon resembles the color salmon, but is darker.

Legume
A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse. Legumes are grown agriculturally, primarily for human consumption, for livestock forage and silage, and as soil-enhancing green manure. Well-known legumes include beans, soybeans, chickpeas, peanuts, lentils, lupins, mesquite, carob, tamarind, alfalfa, and clover. Legumes produce a botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces (opens along a seam) on two sides. Legumes are notable in that most of them have symbiotic nitrogen-fixing bacteria in structures called root nodules. For that reason, they play a key role in crop rotation. Terminology The term ''pulse'', as used by the United Nations' Food and Agriculture Organization (FAO), is reserved for legume crops harvested solely for the dry seed. This excludes green beans and green peas, which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
