Brasiliopuntia

Brasiliopuntia is a genus in the cactus family, Cactaceae. It contains only one species, Brasiliopuntia brasiliensis.
It is found in Brazil, Paraguay, eastern Bolivia, Peru and northern Argentina, and has become naturalized in Florida among other places.
Description.
"Brasiliopuntia brasiliensis" shows thin, slightly shrunken cladodes on a central cylindrical trunk. The leaves are bright green. Its white areoles bear one or two small brown upright spines. Its light brown flowers appear only on adult plants.
Systematics.
"Brasiliopuntia brasiliensis" was placed in the genus "Opuntia" when the very broad genus "Cactus" was dismembered. The distinctive features of the species were recognized by Karl Schumann in 1898 when he created a subgenus "Brasiliopuntia" within the genus "Opuntia". In 1926 Alwin Berger completed the separation from "Opuntia" by raising "Brasiliopuntia" to a full genus. A number of species have been described in the past, but are now considered only to be variants of "B. brasiliensis".
