Nassella Pulchra
''Nassella pulchra'', basionym ''Stipa pulchra'', is a species of grass known by the common names purple needlegrass and purple tussockgrass. It is native to the U.S. state of California, where it occurs throughout the coastal hills, valleys, and mountain ranges, as well as the Sacramento Valley and parts of the Sierra Nevada foothills, and Baja California. It grows in many types of local habitat, including grassland, chaparral, and oak woodland. It grows well on clay and serpentine soils. Description ''Nassella pulchra'' is a perennial bunch grass producing tufts of erect, unbranched stems up to tall. The extensive root system can reach deep into the soil, making the grass more tolerant of drought.California Native Perennial Grasses. Hastings Natural History Reservation. The open, nodding |
Albert Spear Hitchcock
Albert Spear Hitchcock (September 4, 1865 – December 16, 1935) was an American botanist and agrostologist. Hitchcock graduated from the Iowa Agricultural College with bachelor's degree in 1884 and M.S. in 1886. From 1892 to 1901 he was a professor of botany at the Kansas State Agricultural College. Hitchcock joined the USDA in 1901 as Assistant Agrostologist under Frank Lamson-Scribner. In 1905 he was put in charge of the grass herbarium and became Systematic Agrostologist. After 1928, he held the title of Principal Biologist in charge of Systematic Agrostology of the Department of Agriculture and kept that title until his death in 1935. In 1912 he became Custodian of Grasses, Division of Plants, United States National Museum. Hitchcock remained Custodian without remuneration until his death. His field notebooks are archived in the Smithsonian Institution. He was a professor of botany in the Kansas State Agricultural College and authored over 250 works during his lifetime. ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Flora Of Baja California
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. 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) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grasses Of Mexico
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Bunchgrasses Of North America
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any habitat ...

Nassella
''Nassella'', or needlegrass, is a New World genus of over 100 perennial bunchgrasses found from North America through South America. The Latin word ''nassa'' refers to "a basket with a narrow neck". It is usually considered segregate from the genus ''Stipa'' and includes many New World species formerly classified in that genus. As of 2011, ''The Jepson Manual'' includes ''Nassella'' within ''Stipa''. ''Nasella'' is characterized by strongly overlapping lemma margins and reduced, veinless paleae. The lemma tips are fused into the "crown", a short membrane that surrounds the base of the lemma. The rim of the crown usually has hairs. Many species form both cross-pollinating and self-pollinating florets in the terminal panicle. The self-pollinating florets have 1–3 small anthers; the cross-pollinating florets have 3 longer anthers. Some species have self-pollinating inflorescences hidden in their basal leaf sheaths. These hidden inflorescences lack glumes and usually lack awn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Common Branded Skipper
''Hesperia comma'', the silver-spotted skipper or common branded skipper, is a butterfly of the family Hesperiidae. It is known as silver-spotted skipper in Europe and common branded skipper in North America where the butterfly ''Epargyreus clarus'', a spread-winged skipper, also has the common name of "silver-spotted skipper". Appearance, behaviour and distribution Often confused with the large skipper ''Ochlodes venata'', this species is easily distinguished by the numerous white spots on the underside hindwings, and the tips of the upper forewings tend to be darker than those of the large skipper. Also their flight periods rarely overlap; in Britain the large skipper has all but finished when the silver-spotted takes to the wing in August. The silver-spotted skipper prefers warm calcareous sites and has a wide distribution as far south as North Africa, northwards throughout Europe to the Arctic and eastwards across Asia to China and Japan. It also has subspecies in North Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Ranchos Of California
The Spanish and Mexican governments made many concessions and land grants in Alta California (now known as California) and Baja California from 1775 to 1846. The Spanish Concessions of land were made to retired soldiers as an inducement for them to remain in the frontier. These Concessions reverted to the Spanish crown upon the death of the recipient. The Mexican government later encouraged settlement by issuing much larger land grants to both native-born and naturalized Mexican citizens. The grants were usually two or more square leagues, or in size. Unlike Spanish Concessions, Mexican land grants provided permanent, unencumbered ownership rights. Most ranchos granted by Mexico were located along the California coast around San Francisco Bay, inland along the Sacramento River, and within the San Joaquin Valley. When the government secularized the Mission churches in 1833, they required that land be set aside for each Neophyte family. But the Native Americans were quickly ...
