Rhipsalidopsis
''Rhipsalidopsis'' is a small genus of flowering plant in the family Cactaceae, native to southern Brazil. Like other members of the tribe Rhipsalideae, its species are epiphytes, growing on trees. Taxonomy The genus ''Rhipsalidopsis'' was established by Nathaniel Lord Britton and Joseph Nelson Rose in 1923. The generic name means 'like ''Rhipsalis'''. They transferred one species from ''Rhipsalis'' to their new genus as ''Rhipsalidopsis rosea''. The presence of a short tube at the base of the flower where the petals were fused was regarded as one of the diagnostic features. The taxonomy of genera like ''Rhipsalidopsis'' that are placed in the tribe Rhipsalideae was described as confused by Anderson in 2001, with species moved among ''Rhipsalis'', ''Hatiora'' and ''Schlumbergera'' in particular. A molecular phylogenetic study in 2011 showed that two species then placed in ''Hatiora'' were separate from other species in the genus and could be placed in an expanded ''Schlumbergera ...

Rhipsalidopsis Gaertneri
''Rhipsalidopsis gaertneri'', synonyms ''Schlumbergera gaertneri'' and ''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 '' R. rosea'', ''Rhipsalidopsis'' × ''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 ''Rhipsalidopsis gaertneri'' is found in southeastern Brazil, in Paraná and Santa Catarina, at altitudes of . ''R. 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 ...

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 berry. ...

Schlumbergera
''Schlumbergera'' is a small genus of cactus, 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. 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 which they flower in the Southern Hemisphere. Most of the popular houseplants are cultivars of ''Schlumbergera'', rather than species, with flowers in white, pink, yellow, orange, red or ...

Rhipsalideae
The Rhipsalideae are a small tribe of cacti, comprising four or five 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 The tribe Rhipsalideae was established by Augustin Pyramus de Candolle in 1828. De Candolle included only one genus, ''Rhipsalis''. Cacti belonging to the Rhipsalideae 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhipsalidopsis Rosea
''Rhipsalidopsis rosea'', synonyms ''Hatiora rosea'' and ''Schlumbergera rosea'', is a species of flowering plant in the family Cactaceae A cactus (: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae (), a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. The word ''cactus'' derives, through Latin, ..., native to south Brazil. It was first described, as ''Rhipsalis rosea'', by Gustaf Lagerheim in 1912. It is one of the parents of the hybrid ''Rhipsalidopsis'' × ''graeseri'', grown as the Easter or Whitsun cactus.

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized Author citation (botany), author abbreviations. These were initially based on Authors of Plant Names, Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium (Australian Plant Name Index, APNI). The IPNI database is a collection of the names registered by the three cooperating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
