Polaskia
''Polaskia'' (named after American amateur Charles Polaski) is a genus of tree-like cacti reaching 4–5 m high, comprising 2 species. Both present primitive characteristics, but ''Polaskia chichipe'' is nearer to ''Myrtillocactus'' while '' Polaskia chende'' is nearer to '' Stenocereus''. The genus is found in the Mexican states of Puebla and Oaxaca. Description The tree-like, highly branched species of the Polaskia genus reach heights of growth of between 4 and 5 meters and form dense crowns 3 to 4 meters above the ground. Its bright green shoots repeatedly fork and grow 1 to 2 meters long. The 7 to 12 ribs are sharply triangular in cross-section. On their edges, these wear 3 to 4 millimeters wide, shield-shaped areoles at close intervals. The central spine may be absent. The 3 to 8 radial spines are greyish to blackish. The urn- to bell-shaped flowers are white to creamy white to yellowish green. They open day and night and are between 4 and 6 centimeters long. The red, sp ...

Echinocereeae
The Echinocereeae are a tribe of cacti in the subfamily Cactoideae. Since 2006, the tribe has included the former tribe Pachycereeae in many treatments of cactus classification. The exact circumscription of the tribe has been subject to considerable change, particularly since molecular phylogenetic approaches have been used in determining classifications, and remains uncertain. The tribe includes large treelike species, such as the saguaro (''Carnegiea gigantea''), as well as shorter shrubby species. Most members of the tribe are found in desert regions, particularly in Mexico and the southwestern United States. Description The tribe includes large treelike species, as well as shorter shrubby species. Some species can grow to be over tall, like the saguaro (''Carnegiea gigantea'') and '' Neobuxbaumia macrocephala''. Their stems are ribbed and columnar, not divided into segments. Most have flowers that open at night. Taxonomy In 1958, Franz Buxbaum published a division into tribe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stenocereus
''Stenocereus'' ( Gk. ''stenos'', narrow, L. ''cereus'', candle) is a genus of columnar or tree-like cacti from the Baja California Peninsula and other parts of Mexico, Arizona in the United States, Colombia, Costa Rica, Guatemala, Venezuela and the ABC islands of the Dutch Caribbean. The genus has been enlarged by the addition of species from several other genera. A close relative is the peculiar chinoa or chende cactus, '' Polaskia chende''. Description The flowers are mostly borne near the apex of the stems and mostly nocturnal. They are considered easy to grow and generally grow slowly. '' Stenocereus thurberi'' (the organ pipe cactus) is a well-known member of this genus and is widely distributed in Arizona and northern Mexico. The fruit is similar to a dragon fruit. Those of '' Stenocereus gummosus'', acidic and very refreshing, are highly favored by the Seris of northwestern Mexico who call the cactus ''ziix is ccapxl'' - "thing whose fruit is sour".

Flora Of Oaxaca
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 Thur ...

Endemic Flora Of Mexico
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cacti Of Mexico
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 spines ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...
