Evergreen
In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. Evergreen species There are many different kinds of evergreen plants, both trees and shrubs. Evergreens include: *Most species of conifers (e.g., pine, hemlock, blue spruce, and red cedar), but not all (e.g., larch) * Live oak, holly, and "ancient" gymnosperms such as cycads *Most angiosperms from frost-free climates, and rainforest trees *All Eucalypts * Clubmosses and relatives *Bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance :'' Cupressus sempervirens'' (a cypress) :'' Lonicera sempervirens'' (a honeysuckle) :'' Sequoia sempervirens'' (a sequoia) Leaf longevity in evergreen plants varies from ...

Dioecious
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about fiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Nevada De Santa Marta
The Sierra Nevada de Santa Marta (English: ''Snow-Covered Mountain Range of Saint Martha'') is an isolated mountain range in northern Colombia, separate from the Andes range that runs through the north of the country. Reaching an elevation of just from the Caribbean coast, the Sierra Nevada is the highest coastal range in the tropics, and one of the highest coastal ranges in the world, being shorter than the Saint Elias Mountains in Canada. The Sierra Nevada encompasses about and serves as the source of 36 rivers. The range is in the Departments of Magdalena, Cesar and La Guajira. The highest point of the Sierra Nevada group (and Colombia in general) may be either Pico Cristóbal Colón or Pico Simón Bolívar, both in the municipalities of Santa Marta and Aracataca; it has yet to be determined which is higher. SRTM data and local topographic maps show that their true elevations are approximately , lower than the elevation that is often quoted. The Sierra Nevada i ...

Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization.

Leaves
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light en ...

Siparunaceae
Siparunaceae is a family of flowering plants in the magnoliid order Laurales. It consists of two genera of woody plants, with essential oils: ''Glossocalyx'' in West Africa and ''Siparuna'' in the neotropics. ''Glossocalyx'' is monospecific (''Glossocalyx longicuspis'') and ''Siparuna'' has about 74 known species. Until the 1990s, most taxonomists placed ''Glossocalyx'' and ''Siparuna'' in the family Monimiaceae. The monograph of Monimiaceae by William R. Philipson in 1993 was the last major work to do so. In the 1990s, molecular phylogenetic studies of DNA sequences showed that Monimiaceae, as then circumscribed, was paraphyletic. When the Angiosperm Phylogeny Group published their APG system in 1998, the old Monimiaceae was divided into three separate families: Siparunaceae, Atherospermataceae, and Monimiaceae sensu stricto. This classification remained unchanged in the APG III system of 2009 and the APG IV system of 2016. The families Siparunaceae, Gomortegaceae, and Ather ...

Flora Of Colombia
The Flora of Colombia is characterized by over 28,000 species of green plants. National Flower of Colombia The national flower of Colombia is the orchid ''Cattleya trianae'' which was named after the Colombian naturalist José Jerónimo Triana. The orchid was selected by botanist Emilio Robledo, in representation of the Colombian Academy of History to determine the most representative flowering plant of Colombia. He described it as one of the most beautiful flowers in the world and selected ''Cattleya trianae'' as National symbol. National Tree of Colombia The national tree of Colombia is the palm '' Ceroxylon quindiuense'' (Quindío wax palm) which was named after the Colombian Department of Quindío where is located the Cocora valley, the only habitat of this restricted range species. The Quindío wax palm was selected as the national tree by the government of Belisario Betancur and was the first tree officially declared as a protected species in Colombia. ''C.quindiue ...
