× ''Haagespostoa'' is a hybrid genus of cacti, a natural hybrid between ''Haageocereus'' and ''Espostoa ''Espostoa'' is a genus of columnar cacti, comprising 16 species known from the Andes of southern Ecuador and Peru. It usually lives at an altitude of between 800m and 2500m. Its fruit is edible, sweet, and juicy. The genus is named after Nicola ...,'' exclusively found in Peru. Backeberg took this taxon for a new genus, and described it as ''Neobinghamia''. According to Ostolaza (Quepo 2009), five taxa are known, all situated west of the Andes. The genus ''× Haagespostoa'' is in the family ''Cactaceae'' in the major group ''Angiosperms'' (Flowering plants). Habitat The genus × ''Haagespostoa'' grows endemically in Peru on mountainous slopes in rocky masses, in ravines (quebradas) and valleys, between 300 m and 1820 m in altitude. Populations are obviously rare and limited. Distribution Peru (Ancash, Lambayeque, Lima) References Haageocereus Trichocereeae ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

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 spines, ...

Espostoa
''Espostoa'' is a genus of columnar cacti, comprising 16 species known from the Andes of southern Ecuador and Peru. It usually lives at an altitude of between 800m and 2500m. Its fruit is edible, sweet, and juicy. The genus is named after Nicolas E. Esposto, a renowned botanist from Lima. These candle-like cacti are covered with spines and white hair. Only the older specimens can divide. In adulthood, a cephalium sometimes appears, similar to the Mexican genus Cephalocereus. They were discovered by Alexander von Humboldt and Aimé Bonpland in the early nineteenth century. They are appreciated for their decorative qualities due to their white fleece. They can be propagated by seed. For full development they must be planted in the ground. The cultivated specimens very rarely flourish. Like all cacti, Espostoa requires a sunny location and well-drained soil. But in summer, it appreciates fertilizer and wetter conditions. In winter, it needs a rest, but the temperature must not ...

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.

Cactoideae Genera
The Cactoideae are the largest subfamily of the cactus family, Cactaceae. Around 80% of cactus species belong to this subfamily. , the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. Various revisions have been published since, e.g. to the tribe Hylocereeae and the tribe Echinocereeae. Classifications remained uncertain . Tribes and genera , the National Center for Biotechnology Information used the division of the subfamily into tribes shown below. Some revisions to the circumscriptions of the tribes are also shown. * Blossfeldieae **''Blossfeldia'' *Browningieae **''Armatocereus'' – ''Browningia'' – '' Neoraimondia'' – '' Stetsonia'' *Cacteae **''Acharagma'' – ''Ariocarpus'' – '' Astrophytum'' – ''Aztekium'' – '' Coryphantha'' – '' Cumarinia'' – ''Ech ...
