|Taxonomic Source(s):||Hunt, D., Taylor, N. and Charles, G. (compilers and editors). 2006. The New Cactus Lexicon. dh Books, Milborne Port, UK.|

This species has a very small extent of occurrence and area of occupancy, and today it is only known from public parks in the greater urban area of Rio de Janeiro. There is likely to be continuing decline due to the impacts of the urban environment, especially as the city gets warmer and drier. The species is therefore listed as Criticially Endangered and it is potentially extinct in the wild as it no longer occurs in any natural habitat even though it has colonized the urban areas.
|Range Description:||This species is endemic to Brazil, occurring in Rio de Janeiro in the city of Rio and on the other side of the bay at Nitaroi from sea level up to 600 m asl (Hunt et al. 2006).|
Native:Brazil (Rio de Janeiro)

|Population:||The population comprises at the most just a few thousand individuals.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species occurs as an epiphyte on trees in public parks. The original habitat was presumably lowland forest.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||It is cultivated widely as an ornamental.|
|Major Threat(s):||The main threat is urbanization, although all that is left of the species are plants growing on trees in public parks.|
|Conservation Actions:||It occurs in public parks which afford some protection, although these are not designated protected areas. The survival of the species is dependent on the appropriate management of these parks; especially Parque Laje.|
