Central American Montane Forests
The Central American montane forests are an ecoregion of the tropical and subtropical moist broadleaf forests biome, as defined by the World Wildlife Fund, located in mountains of Central America. Geography Central American montane forests consist of forest patches located at altitudes ranging from , on the summits and slopes of the highest mountains in Central America, including the Sierra Madre de Chiapas. It extends from Chiapas state in southeastern Mexico, through Guatemala, El Salvador, and Honduras, to northern Nicaragua. The montane forests ecoregion is surrounded at lower elevations by the Central American pine–oak forests, except for the enclaves in northern Guatemala, northern Honduras, and central Nicaragua, which are bounded by the Central American Atlantic moist forests. The ecoregion covers an area of 2. The ecoregion has a temperate climate with relatively high precipitation levels. Climate The climate is humid and montane. Average annual rainfall ranges f ...

Pinus Hartwegii
''Pinus hartwegii'' (syn. ''P. rudis'', ''P. donnell-smithii''), Hartweg's pine or pino de las alturas, is a pine native to the mountains of Mexico and Central America east to Honduras. It is named after Karl Theodor Hartweg, who described it in 1838. Distribution ''Pinus hartwegii'' is a very high elevation species, growing at elevations of . It forms the alpine tree line on most of Mexico's higher mountains. It grows on both the Sierra Madre Occidental and Sierra Madre Oriental (mountain ranges) (29° North latitude) from Chihuahua State and Nuevo León (26°) to the highest peaks in the mountain ranges on the El Salvador— Honduras border (15° North latitude). In the Sierra Madre Occidental this pine grows with very dry winters and a very heavy rainy season in summer, with constant frosts from October to March. This pine does not acquire the dwarfed and contorted shape shared by many species at high elevation. Even at the alpine tree line, this tree is not damaged by the ...

Temperate Climate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the A ...

''Gnaphalium'' is a genus of flowering plants in the family Asteraceae, commonly called cudweeds. They are widespread and common in temperate regions, although some are found on tropical mountains or in the subtropical regions of the world.

Gentiana Pumilio
''Gentiana'' is a genus of flowering plants belonging to the gentian family (Gentianaceae), the tribe Gentianeae, and the monophyletic subtribe Gentianinae. With about 400 species it is considered a large genus. They are notable for their mostly large, trumpet-shaped flowers, which are often of an intense blue. The genus name is a tribute to Gentius, an Illyrian king who may have been the discoverer of tonic properties in gentians. Habitat This is a cosmopolitan genus, occurring in alpine habitats in temperate regions of Asia, Europe and the Americas. Some species also occur in northwestern Africa, eastern Australia, and New Zealand. They are annual, biennial, and perennial plants. Some are evergreen, others are not. Many gentians are difficult to grow outside their wild habitat, but several species are available in cultivation. Gentians are fully hardy and can grow in full sun or partial shade. They grow in well-drained, neutral-to-acid soils rich in humus. They are popular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Festuca Tolucensis
''Festuca'' (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (''Lolium''), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus ''Festuca'' into the genus ''Lolium'', or alternatively into the segregate genus ''Schedonorus''. Because the taxonomy is complex, scientists have not determined how many true species belong to the genus, but estimates range from more than 400 to over 640.Darbyshire, S. J. and L. E.

Alchemilla Pinnata
''Alchemilla'' is a genus of herbaceous perennial plants in the family Rosaceae, with the common name lady's mantle applied generically as well as specifically to ''Alchemilla mollis'' when referred to as a garden plant. The plant used as a herbal tea or for medicinal usage such as gynaecological disorders is ''Alchemilla xanthochlora'' or in Middle Europe the so-called common lady's mantle ''Alchemilla vulgaris''. There are about 700 species, the majority native to cool temperate and subarctic regions of Europe and Asia, with a few species native to the mountains of Africa and the Americas. Most species of ''Alchemilla'' are clump-forming or mounded perennials with basal leaves arising from woody rhizomes. Some species have leaves with lobes that radiate from a common point and others have divided leaves—both are typically fan-shaped with small teeth at the tips. The long-stalked, gray-green to green leaves are often covered with soft hairs, and show a high degree of water-res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calamagrostis Vulcanica
''Calamagrostis'' (reed grass or smallweed) is a genus of flowering plants in the grass family Poaceae, with about 260 species that occur mainly in temperate regions of the globe. Towards equatorial latitudes, species of ''Calamagrostis'' generally occur at higher elevations. These tufted perennials usually have hairless narrow leaves. The ligules are usually blunt. The inflorescence forms a panicle. Some may be reed-like. The plants may be rhizomatous (underground stems with shoots), stoloniferous (with runners), or caespitose (growing in tufts or clumps). The bisexual spikelets have a single floret and generally they are purple or purple-brown. The spikelets are clustered into inflorescences, which usually develop in early- to mid-summer on long culms ( = stems). Many species of ''Calamagrostis'' are morphologically similar, but they generally occur in distinct habitats, and they have unique geographical distributions. Given the subtle distinctions between many closely relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lupinus Montanus
''Lupinus'', commonly known as lupin, lupine, or regionally bluebonnet etc., is a genus of plants in the legume family Fabaceae. The genus includes over 199 species, with centers of diversity in North and South America. Smaller centers occur in North Africa and the Mediterranean. They are widely cultivated, both as a food source and as ornamental plants, but are invasive to some areas.

An exception is the ''chamis de monte'' (''Lupinus jaimehintoniana'') of Oaxaca in Mexico, which is a tree up to tall. Lupins have soft green to grey-green leaves which may be coated in silvery hairs, often densely so. The leaf blades are usually palmately divided into five to 28 leaflets, or reduced to a single leaflet in a few species of the southeastern United States and eastern South America.
