Tamá Massif
The Tamá Massif ( es, Macizo del Tamá) is a group of mountains on the border between Colombia and Venezuela to the south of Lake Maracaibo. It contains evergreen rainforest and cloud forest at the lower levels, and páramos (high moors) at the highest levels. Location The Tamá is a prolongation of the Cordillera Oriental of the Colombian Andes. It is separated from the Cordillera de Mérida in the Venezuelan Andes by the Táchira depression, which more than 50 million years ago was a strait that connected Lake Maracaibo with the Orinoco basin. Elevations range from . Average annual temperature is . Average annual rainfall is . The Tamá National Natural Park in Colombia and the El Tamá National Park in Venezuela protect parts of the Tamá Massif. The two parks together form a protected area of .

San Cristóbal, Táchira
San Cristóbal () is the capital city of the Venezuelan state of Táchira. It is located in a mountainous region of Western Venezuela. The city is situated above sea level in the northern Andes overlooking the Torbes River, from the Colombian border. San Cristóbal was founded on March 31, 1561, by Juan de Maldonado. From its inception, the city evolved rapidly as one of the most progressive and important centers of commerce in the country, due primarily to its rich soil and its proximity to the border with Colombia. The city was severely damaged by the Earthquake of Cúcuta (also known as Earthquake of the Andes) in 1875. The city is located on the Pan-American Highway. Education San Cristobal has a large student population. There are many post-secondary schools, both public and private, in San Cristobal. The main higher education facilities are: * Universidad Nacional Experimental del Táchira (UNET) * Universidad de los Andes (ULA) * Universidad Católica del Táchira ...

Vaccinium
''Vaccinium'' is a common and widespread genus of shrubs or dwarf shrubs in the heath family (Ericaceae). The fruits of many species are eaten by humans and some are of commercial importance, including the cranberry, blueberry, bilberry (whortleberry), lingonberry (cowberry), and huckleberry. Like many other ericaceous plants, they are generally restricted to acidic soils. Description The plant structure varies between species: some trail along the ground, some are dwarf shrubs, and some are larger shrubs perhaps tall. Some tropical species are epiphytic. Stems are usually woody. Flowers are epigynous with fused petals, and have long styles that protrude from their bell-shaped corollas. Stamens have anthers with extended tube-like structures called "awns" through which pollen falls when mature. Inflorescences can be axillary or terminal. The fruit develops from an inferior ovary, and is a four- or five-parted berry; it is usually brightly coloured, often being red or bluish wi ...

Utricularia
''Utricularia'', commonly and collectively called the bladderworts, is a genus of carnivorous plants consisting of approximately 233 species (precise counts differ based on classification opinions; a 2001 publication lists 215 species).Salmon, Bruce (2001). ''Carnivorous Plants of New Zealand''. Ecosphere Publications. They occur in fresh water and wet soil as terrestrial or aquatic species across every continent except Antarctica. ''Utricularia'' are cultivated for their flowers, which are often compared with those of snapdragons and orchids, especially amongst carnivorous plant enthusiasts. All ''Utricularia'' are carnivorous and capture small organisms by means of bladder-like traps. Terrestrial species tend to have tiny traps that feed on minute prey such as protozoa and rotifers swimming in water-saturated soil. The traps can range in size from .Taylor, Peter. (1989).

Pinguicula
''Pinguicula'', commonly known as the butterworts, is a genus of carnivorous flowering plants in the family Lentibulariaceae. They use sticky, glandular leaves to lure, trap, and digest insects in order to supplement the poor mineral nutrition they obtain from the environment. Of the roughly 80 currently known species, 13 are native to Europe, 9 to North America, and some to northern Asia. The largest number of species is in South and Central America. Etymology The name ''Pinguicula'' is derived from a term coined by Conrad Gesner, who in his 1561 work entitled ''Horti Germaniae'' commented on the glistening leaves: ''"propter pinguia et tenera folia…"'' (Latin ''pinguis'', "fat"). The common name "butterwort" reflects this characteristic. Characteristics The majority of ''Pinguicula'' are perennial plants. The only known annuals are ''P. sharpii'', ''P. takakii'', ''P. crenatiloba'', and ''P. pumila''. All species form stemless rosettes. Habitat Butterworts can be ...

Gentiana
''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 popul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castilleja
''Castilleja'', commonly known as paintbrush, Indian paintbrush, or prairie-fire, is a genus of about 200 species of annual and perennial herbaceous plants native to the west of the Americas from Alaska south to the Andes, northern Asia, and one species as far west as the Kola Peninsula in northwestern Russia. These plants are classified in the broomrape family Orobanchaceae (following major rearrangements of the order Lamiales starting around 2001; sources which do not follow these reclassifications may place them in the Scrophulariaceae). They are hemiparasitic on the roots of grasses and forbs. The generic name honors Spanish botanist Domingo Castillejo. Ecology ''Castilleja'' species are eaten by the larvae of some lepidopteran species, including '' Schinia cupes'' (which has been recorded on ''C. exserta'') and ''Schinia pulchripennis'' (which feeds exclusively on ''C. exserta''), and checkerspot butterflies, such as ''Euphydryas'' species.

Jamesonia
''Jamesonia'' is a genus of ferns in the subfamily Pteridoideae of the family Pteridaceae. It now includes the formerly separate genus ''Eriosorus''. Description Species of ''Jamesonia'' are terrestrial or grow on rocks. They vary considerably in their detailed morphology. The rhizomes are short, dark brown, and creeping, with a more or less dense covering of hairs and bristles. The fertile and infertile fronds are similar. Species show one of two different frond morphologies, related to habitat. These were formerly used to distinguish ''Jamesonia'' and ''Eriosorus'', but do not correspond to the evolutionary history of the species. Species with "''Jamesonia''-type" morphology have many fronds with short, often leathery pinnae, and are associated with exposed habitats. Species with "''Eriosorus''-type" morphology have fewer fronds with longer, thinner pinnae, and are associated with more sheltered areas including cloud forests. The stalks ( petioles and rachises) of the frond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
