Ephedra (plant)
''Ephedra'' is a genus of gymnosperm shrubs. The various species of ''Ephedra'' are widespread in many arid regions of the world, ranging across southwestern North America, southern Europe, northern Africa, southwest and central Asia, northern China and western South America. It is the only extant genus in its family, Ephedraceae, and order, Ephedrales, and one of the three living members of the division Gnetophyta alongside ''Gnetum'' and ''Welwitschia.'' In temperate climates, most ''Ephedra'' species grow on shores or in sandy soils with direct sun exposure. Common names in English include joint-pine, jointfir, Mormon-tea or Brigham tea. The Chinese name for ''Ephedra'' species is ''mahuang'' (). ''Ephedra'' is the origin of the name of the stimulant ephedrine, which the plants contain in significant concentration. Description The family Ephedraceae, of which ''Ephedra'' is the only genus, are gymnosperms, and generally shrubs, sometimes clambering vines, and rarely, smal ...

Goose
A goose ( : geese) is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera ''Anser'' (the grey geese and white geese) and '' Branta'' (the black geese). Some other birds, mostly related to the shelducks, have "goose" as part of their names. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller. The term "goose" may refer to either a male or female bird, but when paired with "gander", refers specifically to a female one (the latter referring to a male). Young birds before fledging are called goslings. The collective noun for a group of geese on the ground is a gaggle; when in flight, they are called a skein, a team, or a wedge; when flying close together, they are called a plump. Etymology The word "goose" is a direct descendant of,''*ghans-''. In Germanic languages, the root gave Old English ''gōs'' with the plural ''gēs'' and ''gandres'' (b ...

Duck
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darwin's Rhea
Darwin's rhea or the lesser rhea (''Rhea pennata'') is a large flightless bird, the smaller of the two extant species of rheas. It is found in the Altiplano and Patagonia in South America. Description The lesser rhea stands at tall. Length is and weight is . Like most ratites, it has a small head and a small bill, the latter measuring , but has long legs and a long neck. It has relatively larger wings than other ratites, enabling it to run particularly well. It can reach speeds of 60 km/h (37 mph), enabling it to outrun predators. The sharp claws on the toes are effective weapons. Their feathers are similar to those of ostriches, in that they have no aftershaft.Perrins, C. (1987) Their plumage is spotted brown and white, and the upper part of their tarsus is feathered. The tarsus is long and has 18 horizontal plates on the front. Etymology It is known as ''ñandú petiso'', or ''ñandú del norte'', in Argentina, where the majority live. Other names are ''suri ...

Short-tailed Chinchilla
The short-tailed chinchilla (''Chinchilla chinchilla)'' is a small rodent part of the Chinchillidae family and is classified as an endangered species by the IUCN. Originating in South America, the chinchilla is part of the genus ''Chinchilla'', which is separated into two species: the long-tailed chinchilla and the short-tailed chinchilla. Although the short-tailed chinchilla used to be found in Chile, Argentina, Peru, and Bolivia, the geographical distribution of the species has since shifted. Today, the species remains extant in the Andes mountains of northern Chile, but small populations have been found in southern Bolivia. The short-tailed chinchilla is characterized by its grayish-blue fur which is extremely dense and plush. The short-tailed chinchilla has a short furry tail, which distinguishes it from the long-tailed chinchilla. Compared to '' C. lanigera, C. chinchilla'' has smaller, more rounded ears and is slightly smaller in body size. Chinchillas have been exploited by h ...

Southern Viscacha
The southern viscacha (''Lagidium viscacia'') is a species of viscacha, a rodent in the family Chinchillidae found in Argentina, Bolivia, Chile, and Peru. It is a colonial animal living in small groups in rocky mountain areas. It has long ears and hind legs and resembles a rabbit in appearance apart from its long, bushy tail, but is not a lagomorph. Description The southern viscacha has yellowish-grey upperparts, paler underparts, and a black-tipped, bushy tail. The body fur is long and soft, while that on the tail is coarse. The long, fur-covered ears have a white fringe and both the short front legs and longer hind legs have four digits on the feet. The soles of the feet have fleshy pads called "pallipes" and they can move about with agility over rocky surfaces. The weight of an adult southern viscacha is about . Distribution and habitat The southern viscacha is native to the mountainous parts of western Argentina, southern Peru, western and central Bolivia, and northern and ce ...

Glandularia
''Glandularia'', common name mock vervain or mock verbena, is a genus of annual and perennial herbaceous flowering plants in the family Verbenaceae. They are native to the Americas. Description These plants, like their relatives the vervains (verbenas), usually have showy five-petalled flowers in shades of pink, purple and blue. Taxonomy ''Glandularia'' species are closely related to the true vervains and sometimes still included with them in ''Verbena''. Horizontal chloroplast transfer occurred at least twice and possibly three times between these genera, which are otherwise too distinct to warrant unification. Somehow, chloroplasts from '' V. orcuttiana'', swamp verbena ('' V. hastata'') or a close relative of these had admixed into the '' G. bipinnatifida'' genome. Although hybridization runs rampant in the true and mock vervains – the ancestors of the well-known garden vervain are quite obscure – it does not seem to have been the cause of the cross-spec ...

Phacelia
''Phacelia'' (phacelia, scorpionweed, heliotrope) is a genus of about 200 species of annual or perennial herbaceous plants in the borage family, native to North and South America. California is particularly rich in species with over 90 recorded in the region. The genus is traditionally placed at family rank with the waterleafs ( Hydrophyllaceae) in the order Boraginales. The Angiosperm Phylogeny Group, recognizing that the traditional Boraginaceae and Hydrophyllaceae are paraphyletic with respect to each other, merges the latter into the former and considers the family basal in the Euasterids I clade. Other botanists continue to recognize the Hydrophyllaceae and Boraginales after analysing the secondary structure of the ITS1 genetic region rather than its sequence for these higher taxonomic levels. This placed ''Phacelia'' within the Hydrophyllaceae. Further molecular taxonomic analysis of the Boraginales has divided the Boraginales in two and placed ''Phacelia'' among the mo ...

Tropaeolum
''Tropaeolum'' , commonly known as nasturtium (; literally "nose-twister" or "nose-tweaker"), is a genus of roughly 80 species of annual and perennial herbaceous flowering plants. It was named by Carl Linnaeus in his book ''Species Plantarum'', and is the only genus in the family Tropaeolaceae. The nasturtiums received their common name because they produce an oil similar to that of watercress (''Nasturtium officinale''). The genus ''Tropaeolum'', native to South and Central America, includes several very popular garden plants, the most common being '' T. majus'', '' T. peregrinum'' and '' T. speciosum''. One of the hardiest species is '' T. polyphyllum'' from Chile, the perennial roots of which can survive the winter underground at elevations of . Plants in this genus have showy, often intensely bright flowers and rounded, peltate (shield-shaped) leaves with the petiole in the centre. The flowers are bisexual and zygomorphic, with five petals, a superior three-carpelled ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astragalus (plant)
''Astragalus'' is a large genus of over 3,000 species of herbs and small shrubs, belonging to the legume family Fabaceae and the subfamily Faboideae. It is the largest genus of plants in terms of described species. The genus is native to temperate regions of the Northern Hemisphere. Common names include milkvetch (most species), locoweed (in North America, some species) and goat's-thorn ( ''A. gummifer'', ''A. tragacantha''). Some pale-flowered vetches (''Vicia'' spp.) are similar in appearance, but they are more vine-like than ''Astragalus''. Description Most species in the genus have pinnately compound leaves. There are annual and perennial species. The flowers are formed in clusters in a raceme, each flower typical of the legume family, with three types of petals: banner, wings, and keel. The calyx is tubular or bell-shaped. Taxonomy The genus was formally described in 1753 by Carl Linnaeus in his ''Species Plantarum''. The name ''Astragalus'' is Greek, an old n ...
