Description from Arvice30
Schlumbergera truncata is a species of plant in the Cactaceae family.
It is endemic to a small area of the coastal mountains of south-eastern Brazil where its natural habitats are subtropical or tropical moist forests.
Schlumbergera truncata resembles other species of the genus Schlumbergera in that it has leafless green stems which act as photosynthetic organs.
The stems are composed of strongly flattened segments, which have two or three “teeth” of varying shapes along their edges and at the ends.
The ends of the stems are “cut off” (truncated) rather than pointed.
Individual segments are about 46 cm (1.62.4 in) long by 1.53.5 cm (0.61.4 in) wide.
S. truncata occurs only in a small area of the coastal mountains of south-east Brazil, in the state of Rio de Janeiro, located in the southernmost part of the tropics.
Sites where it has been found include the Organ Mountains (Serra dos Órgãos) in the Parque Nacional da Serra dos Órgãos and in the Serra do Mar near to the city of Rio de Janeiro.
Plants grow at altitudes of 7001,000 metres (2,3003,300 ft).
Because of their altitude and proximity to the Atlantic Ocean, the coastal mountains have high humidity warm moist air is forced upwards into higher, colder locations where it condenses.
S. truncata usually grows on trees or on rocks .
