Oreocarya Thompsonii
''Oreocarya thompsonii'' is a species of flowering plant in the genus '' Oreocarya'' with the common name Thompson's cryptantha (it was previously placed in the genus ''Cryptantha''). Description The leaves form a low basal rosette or cluster of rosettes. Individual leaves are linear and gray-green, and are covered with short white hairs, interspersed with much longer hairs especially near the leaf edge (ciliate). The largest basal leaf is about 4–7 cm long and 5–10 mm wide, with progressively smaller leaves higher on the rosette. Flower stems arise from the base of the leaf rosette and are 20–40 cm tall, bearing clusters of small flowers with 5 white petals and a yellow center. The peduncle Peduncle may refer to: *Peduncle (botany), a stalk supporting an inflorescence, which is the part of the shoot of seed plants where flowers are formed *Peduncle (anatomy), a stem, through which a mass of tissue is attached to a body **Peduncle (art ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oreocarya
''Oreocarya'' (Perennial Cat's-Eye) is a genus of flowering plants in the family Boraginaceae. There are about 63 species and its native range extends from western and central Canada, through western United States to north Mexico. It is part of subtribe of ''Amsinckiinae''. It was once thought to be a either a subgenus or synonym of ''Cryptantha'' , as they both had plenty of tiny flowers, hairy leaves, and persisting dried flower stems. Botanist William Alfred Weber later noted that the 2 genera were different in form as ''Oreocarya'' was a "biennial or perennial from rosettes of basal leaves; flowers more than 5 mm in diameter, often distinctly long-tubular with prominent yellow eye", while ''Cryptantha'' was an "annual without rosettes of basal leaves; flowers minute, less than 5 mm diameter, short-tubed with inconspicuous eye". Description They are perennial or biennial, plants. Most species are perennials but a few (such as ''O. setosissima'' and ''O. virgata'') are bienni ...

Cryptantha
''Cryptantha'' is a genus of flowering plants in the borage family, Boraginaceae. They are known commonly as cat's eyes and popcorn flowers (the latter name is also used to refer to the closely related genus ''Plagiobothrys'',Hasenstab-Lehman, K. E. and M. G. Simpson. (2012)Cat's eyes and popcorn flowers: phylogenetic systematics of the genus ''Cryptantha'' s. l. (Boraginaceae).''Systematic Botany'' 37(3), 738-57. and members of the subtribe of ''Amsinckiinae''). They are distributed throughout western North America and western South America, but they are absent from the regions in between. These are annual or perennial herbs usually coated in rough hairs and bearing rounded flower corollas that are almost always white, but are yellow in a few species. Several morphological characters are used to distinguish species from one another, but the most definitive is the form of the nutlet, which varies in shape, size, color, and pattern of attachment.

Ciliate
The ciliates are a group of alveolates characterized by the presence of hair-like organelles called cilia, which are identical in structure to flagellum, eukaryotic flagella, but are in general shorter and present in much larger numbers, with a different wikt:undulating, undulating pattern than flagella. Cilia occur in all members of the group (although the peculiar Suctoria only have them for part of their biological life cycle, life cycle) and are variously used in swimming, crawling, attachment, feeding, and sensation. Ciliates are an important group of protists, common almost anywhere there is water—in lakes, ponds, oceans, rivers, and soils. About 4,500 unique free-living species have been described, and the potential number of extant species is estimated at 27,000–40,000. Included in this number are many Ectosymbiosis, ectosymbiotic and endosymbiotic species, as well as some Obligate parasite, obligate and Facultative parasite, opportunistic parasites.

Peduncle (botany)
In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphylls) at nodes. The main axis of an inflorescence above the peduncle is the rachis. There are no flowers on the peduncle but there are flowers on the rachis. When a peduncle arises from the ground level, either from a compressed aerial stem or from a subterranean stem (rhizome, tuber, bulb, corm), with few or no bracts except the part near the rachis or receptacle, it is referred to as a scape. The acorns of the pedunculate oak are borne on a long peduncle, hence the name of the tree. See also *Pedicel (botany) *Scape (botany) In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle. Typically it takes the form of a long, leafles ... Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wenatchee Mountains
The Wenatchee Mountains are a range of mountains in central Washington State, United States of America. A major subrange of the Cascade Range, extending east from the Cascade crest, the Wenatchee Mountains separate the drainage basins of the Yakima River from the Wenatchee River. The crest of the range forms part of the boundary between Chelan and Kittitas Counties. Extent Fred Beckey describes the Wenatchee Mountains as the area between the Wenatchee and Yakima rivers and Stevens Pass. Among the range's significant features he describes are Mount Stuart, the second highest non-volcanic peak in Washington and one of the largest single granitic mountains in the United States, the Cashmere Crags, the Lost World Plateau, Edward Plateau, and Dragontail Plateau, the Enchantment Lakes Basin ("one of the most marvelous examples of an ice-sculpted wilderness in the Cascade Range″), Icicle Creek and its narrow, U-shaped valley over deep, one of the deepest in the Cascades, and the ...
