Description ''Cleistocactus hyalacanthus'' flowers sprout from the center of needle clusters. They first appear as small dark spots, which gradually enlarge over a week or ten days into long red flowers, each of which is only open, and only slightly, for one day. They are food for hummingbirds, which are attracted by the vivid red color. Those flowers that have been fertilized will develop a fruit which is 1 cm in diameter. The fruits eventually turn yellow when they are ripe. They are food for larger birds, which disperse the small black ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spin ...

Cleistocactus
''Cleistocactus'' is a genus of flowering plants in the cactus family Cactaceae, native to mountainous areas - to - of South America (Peru, Uruguay, Bolivia and Argentina). The name comes from the Greek ''kleistos'' meaning closed because the flowers hardly open. The stems of these cacti are tall, mostly slender and often many-branched with numerous ribs with closely set areoles and spines. The flowers are tubular and the tips hardly open with only the style and stamens usually protruding.

Flowers
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichocereeae
Trichocereeae is a tribe of cactus that are particular to South America. There are 25 recognized genera in this tribe. Description Arborescent to shrubby, Trichocereeae normally form unsegmented, spherical to columnar stems that are usually ribbed, tuberculate, or ribbed-warty. The small to fairly large, regular or bilaterally symmetrical flowers appear laterally or below the apex and open day or night. The flower cup is scaled or covered with hair. The fruits are fleshy to berry-like and sometimes burst open lengthwise. They contain small to medium-sized seeds that vary in shape. Hilum and micropyle of seeds are fused to united. Appendages are usually absent. A strophic is present in some. Genera *''Acanthocalycium'' *''Arthrocereus'' *'' Brachycereus'' *''Cleistocactus'' *'' Denmoza'' *'' Discocactus'' *'' Echinopsis'' *''Espostoa'' *''Espostoopsis'' *''Facheiroa'' *'' Gymnocalycium'' *''Haageocereus'' *'' Harrisia'' *''Leocereus'' *'' Matucana'' *'' Mila'' *''Oreocereus'' ...

Flora Of Argentina
The Environment of Argentina is characterised by high biodiversity. Biodiversity Subtropical plants dominate the Gran Chaco in the north, with the ''Dalbergia'' genus of trees well represented by Brazilian rosewood and the quebracho tree; also predominant the wacho white and black algarrobo trees ('' Prosopis alba'' and '' Prosopis nigra''). Savannah-like areas exist in the drier regions nearer the Andes. Aquatic plants thrive in the wetlands of Argentina. In central Argentina the ''humid pampas'' are a true tallgrass prairie ecosystem. The original pampa had virtually no trees; some imported species like the American sycamore or eucalyptus are present along roads or in towns and country estates (''estancias''). The only tree-like plant native to the pampa is the evergreen Ombú. The surface soils of the pampa are a deep black color, primarily mollisols, known commonly as ''humus''. This makes the region one of the most agriculturally productive on Earth; however, this is als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Bolivia
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurm ...
