Hatiora
''Hatiora'' is a small genus of epiphytic cacti which belongs to the tribe Rhipsalideae within the subfamily Cactoideae of the Cactaceae. Recent taxonomic studies have led to the three species formerly placed in subgenus ''Rhipsalidopsis'' being removed from the genus, including the well known and widely cultivated ornamental plants known as Easter cactus or Whitsun cactus (cultivars or hybrids of the former '' Hatiora gaertneri''). Description All ''Hatiora'' species are found as epiphytes growing on trees or (rarely) lithophytes growing on rocks. They are found in the tropical rainforests of the Mata Atlântica in eastern Brazil. The plants are weakly succulent, growing more or less upright and becoming woody at the base when older. Spines are usually missing. The insect-pollinated flowers are borne terminally. They are small, with a diameter of about , actinomorphic (radially symmetrical), bell-shaped and always coloured (yellow, yellow-orange or pink). The fruit is a berr ...

Hatiora Salicornioides
''Hatiora salicornioides'', the bottle cactus, dancing-bones, drunkard's-dream, or spice cactus, is a species of flowering plant in the cactus family. A member of the tribe Rhipsalideae, it often grows as an epiphyte. It is native to eastern Brazil. It is sometimes grown both indoors and outdoors as an ornamental. Description ''Hatiora salicornioides'' grows to about tall with an erect to pendent growth habit. Its stems are composed of segments long. Each segment is shaped like a club or bottle, with the narrower end at the base. The stems branch from the end of a segment, with up to six branches forming a whorl. The yellow to orange flowers are borne at the ends of younger stem segments, and are long and about the same across when open. Translucent white berries follow the flowers.

Hatiora Cylindrica
''Hatiora cylindrica'' is a species of often epiphytic cactus in the tribe Rhipsalideae within the subfamily Cactoideae. It is native to east Brazil, where it grows in a variety of habitats, including moist forest, dunes and coastal rocks. Description ''Hatiora cylindrica'' is closely related to ''Hatiora salicornioides'', and has been included within that species. Like ''H. salicornioides'', it is a leafless perennial with many branched green stems made up of individual segments. These are strictly cylindrical as opposed to bottle-shaped in ''H. salicornioides''. Its flowers, borne at the end of the stems, have many yellow to orange petals and open quite widely. They are followed by white fruits. Taxonomy ''Hatiora cylindrica'' was first described by Nathaniel Britton and Joseph Rose in 1923. It has not always been viewed as a separate species, being included in '' H. salicornioides'' as either the form or the variety ''cylindrica''. Molecular phylogenetic studie ...

Schlumbergera
''Schlumbergera'' is a small genus of cacti with six to nine species found in the coastal mountains of south-eastern Brazil. These plants grow on trees or rocks in habitats that are generally shady with high humidity, and can be quite different in appearance from their desert-dwelling cousins. Most species of ''Schlumbergera'' have stems which resemble leaf-like pads joined one to the other and flowers which appear from areoles at the joints and tips of the stems. Two species have cylindrical stems more similar to other cacti. Recent phylogenetic studies using DNA have led to three species of the related genus '' Hatiora'' being transferred into ''Schlumbergera,'' though this change is not universally accepted. Common names for these cacti generally refer to their flowering season. In the Northern Hemisphere, they are called Christmas cactus, Thanksgiving cactus, crab cactus and holiday cactus. In Brazil, the genus is referred to as (May flower), reflecting the period in whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhipsalideae
The Rhipsalideae are a small tribe of cacti, comprising four genera (and around 60 species). They grow on trees (epiphytes) or on rocks (lithophytes), where they either hang down or form creeping or upright shrubs. Their flowers open in the day and remain open at night; they may be either radially symmetrical (regular) or bilaterally symmetrical (zygomorphic). The fruits are berry-like, fleshy with smallish seeds. They are found mainly in the east of South America, with a centre of diversity in Bolivia, but some species occur in Central America and North America; one species, ''Rhipsalis baccifera'', also occurs in the Old World. Taxonomy Cacti belonging to the Rhipsalidae are quite distinct in appearance and habit from other cacti, growing on trees or rocks as epiphytes or lithophytes, and are thus easily distinguished. However, for many years there has been confusion as to how to divide the tribe into genera. For example, in 1858 Charles Lemaire recognized the distinctiveness ...

Schlumbergera Gaertneri
''Schlumbergera gaertneri'', formerly ''Hatiora gaertneri'', is a species of epiphytic cactus which belongs to the tribe Rhipsalideae within the subfamily Cactoideae of the Cactaceae. Together with the hybrid with '' S. rosea'', ''Schlumbergera'' × ''graeseri'', it is known, in English speaking countries in the Northern Hemisphere, as Easter cactus or Whitsun cactus and is a widely cultivated ornamental plant. It has received the Royal Horticultural Society's Award of Garden Merit. Description ''Schlumbergera gaertneri'' is found in southeastern Brazil, in Paraná and Santa Catarina, at altitudes of . As with other species of the genus, ''S. gaertneri'' grows on trees (epiphytic) or less often rocks (lithophytic) in sub-tropical rain forest. With maturity, it develops into a branching pendant leafless shrub with a woody base. The stems are made up of segments, most of which are flattened and which are the photosynthetic organs (cladodes) of the plant. Younger segments ...

Schlumbergera Lutea
''Schlumbergera lutea'', synonym ''Hatiora epiphylloides'', is a species of flowering plant in the family Cactaceae, subfamily Cactoideae, native to southeast Brazil. It is a shrubby epiphyte, with flattened stems and bright yellow flowers. Description ''Schlumbergera lutea'' is an epiphyte, with a shrubby growth habit and often pendant stems. The stems are made up of somewhat triangular segments, long and up to wide. It has very small areoles that are without spines. The flowers are bright yellow, long. Taxonomy The species was first described in 1935, as ''Rhipsalis epiphylloides''. It was transferred to the genus ''Hatiora'' in 1983. The generic boundaries within the tribe to which it belongs, Rhipsalideae, have long been unclear. On the basis of a molecular phylogenetic study in 2011, the species was transferred to the genus ''Schlumbergera''. Since the name "''Schlumbergera epiphylloides''" had already been used for a different species, Calvente and Zappi published th ...

List Of Taxa Named By Anagrams
In the biological nomenclature codes, an anagram can be used to name a new taxon. Wordplays are one source of inspiration allowing organisms to receive scientific names. In the binomial nomenclature, as scientists have latitude in naming genera and species, a taxon name can therefore be an anagram, provided it remains pronounceable. For example, in the ''International Code of Nomenclature for algae, fungi, and plants'', a new generic name can be taken from the name of a person by using an anagram or abbreviation of it. William Elford Leach was among the first naturalists to use taxonomic anagrams, and, in 1818, he described several isopod genera that were each other's anagrams of 'Caroline' : '' Conilera'', '' Lironeca'', '' Nerocila'', '' Olencira'', and ''Rocinela ''Rocinela'' is a genus of isopods in the family Aegidae, and was first described in 1818 by William Elford Leach.Bruce, Niel L.; Schotte, M.

Cactoideae
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'' – ''Echino ...

Cactaceae
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 Thorns, s ...

Succulent Plant
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaf, leaves and Plant stem, stems. The water content of some succulent organs can get up to 90–95%, such as ''Glottiphyllum semicyllindricum'' and ''Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in Alpine climate, alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

Berry (botany)
In botany, a berry is a fleshy fruit without a stone (pit) produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines) and bananas, but exclude certain fruits that meet the culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more carpels from the same flower (i.e. from a simple or a compound ovary). The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as peppers, with air rather than pulp around their seeds. Many berries are edible, but others, such as the fruits of the potato and the deadly nightshade, are poisonous to humans. A plant that bears berries is said to be bacciferous or baccate (a fruit that resembles a ber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
