Pseudorhipsalis
''Pseudorhipsalis'' is genus of cacti. This genus is often included in '' Disocactus''. It is epiphytic, many branched, and elongated with flattened, serrated cladodes. In its early life, it stands erect, but soon becomes prostrate. It produces numerous flowers. Description This genus is similar to '' Rhipsalis'' in that epiphytic species with small creamy white flowers are found. However, the flowers are different in that the ovaries and parts of the perianth are connected and the fruits have scales. Also, this genus is limited to Central America, with the exception of one species that ranges in South America. Areoles are small along the stem margin, usually at a higher level. From these areoles, new stems or flowers form. The flowers are small, short tubes or glasses - creamy white. Fruits are small berries that can be white or reddish in color. This genus is very scarce in cultivation. Species A 2017 study of the tribe Hylocereeae accepted the following species: One spe ...

Pseudorhipsalis Amazonica
''Pseudorhipsalis amazonica'' is a species of ''Pseudorhipsalis'' found in Costa Rica, Panama, Brazil, Colombia, Ecuador, Peru, and Venezuela Venezuela (; ), officially the Bolivarian Republic of Venezuela ( es, link=no, República Bolivariana de Venezuela), is a country on the northern coast of South America, consisting of a continental landmass and many islands and islets in th ... Description ''Pseudorhipsalis amazonica'' grows richly branched, with bent to pendulous shoots. The initially upright main shoots are at the base up to 60 centimeters long stalk-like, twisting or two- to three-edged. The upper, leaf-like, flattened part is lanceolate, thornless and has a distinct central rib. It becomes up to 60 (rarely 80) centimeters long and 4 to 7 (rarely 3 to 8.5) centimeters wide. The edges are slightly notched. The side shoots appear from the upper parts of the main shoots, are up to 60 centimeters long and have a stalk-like base up to 4 centimeters long. The areoles are ...

Kimnachia Ramulosa
''Kimnachia'' is a monotypic genus of cacti. Its only species is ''Kimnachia ramulosa'', synonym ''Pseudorhipsalis ramulosa'', which is native from southern Mexico to northern South America and also found in Jamaica. Description ''Kimnachia ramulosa'' is a shrubby plant, branching freely from the base. The stems are rounded basally, with branches that become flattened towards their tips. The branches are long and up to wide. They are reddish at first, later becoming green. The flowers are pinkish or greenish cream in colour, long and across. They are usually borne singly and hang downwards. The small whitish fruits are up to long. Taxonomy The species was first described by Joseph zu Salm-Reifferscheidt-Dyck in 1834, as ''Cereus ramulosus''. It was transferred to the genus ''Pseudorhipsalis'' in 1991. In 1993, Kimnach sank ''Pseudorhipsalis'' into ''Disocactus'' as section ''Pseudorhipsalis'', so ''Ps. ramulosa'' became ''Disocactus ramulosus''. A molecular phylog ...

Hylocereeae
The Hylocereeae are a tribe of cacti. Most are found in the tropical forests of Central and northern South America, and are climbers or epiphytes, unlike most cacti. The tribe includes between six and eight genera in different circumscriptions. The plants known as " epiphyllum hybrids" or "epiphyllums", widely grown for their flowers, are hybrids of species within this tribe, particularly '' Disocactus'', '' Pseudorhipsalis'' and ''Selenicereus'', less often ''Epiphyllum'', in spite of the common name. Description The members of the tribe are very variable in their morphology, especially when the terrestrial ''Acanthocereus'' is included. Many species form aerial roots. The hylocereoid clade (''Selenicereus'', ''Weberocereus'' and probably ''Aporocactus'') are mostly climbing or epiphytic, and have spiny ribbed stems. The phyllocactoid clade (''Epiphyllum'', ''Disocactus'', ''Kimnachia'' and ''Pseudorhipsalis'') are mainly epiphytic, and have spineless flattened leaf-like stem ...

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'' � ...

Disocactus
''Disocactus'' is a genus of epiphytic cacti in the tribe Hylocereeae found in Central America, the Caribbean and northern South America. It should not be confused with ''Discocactus'', which is a different genus. Species of ''Disocactus'' grow in tropical regions either on trees as epiphytes or on rocks as lithophytes. They have two distinct growth habits. Species such as '' D. phyllanthoides'' have stems which are round at the base but then become flattened and leaflike. Many of the cultivated plants known as epiphyllum hybrids or just epiphyllums are derived from crosses between species of ''Disocactus'' (rather than ''Epiphyllum'') and other genera in the Hylocereeae., p. 286 Description The species of the genus ''Disocactus'' grow as epiphytes or lithophytes and are shrubby, profusely branched, hanging, up to 3 m long. The shoots are ribbed or flattened, 3-angled or flattened, ribbon-like, 3–10 mm wide, remotely crenate and leaf-like. The main shoot, which ...
