This species only grows on outcrops and there is a high demand from the quarrying industry for these rock and mining is already happening in the area. Based on this, a decline of over 90% of the population in the next 30 years is projected if mining activities continue at the present rate (the species has a generation length of 10 years), hence it is listed as Critically Endangered. Attempts at legally protecting the species' rocky habitat from exploitation have so far failed.
|Previously published Red List assessments:|
|Range Description:||This species is found at elevations of 250-300 m asl near the Rio Jequitinhonha, north-eastern Minas Gerais, Brazil. The range of this species deserves further investigation, but it is clearly much more restricted than that of its sister species, C. aureus. It is currently known only from a single locality and from three recently discovered subpopulations within a few kilometres of it. The area of occupancy is estimated by experts to be less than 5km2.|
Native:Brazil (Minas Gerais)

|Population:||The species is not abundant, and the population size is less than 1,000 individuals.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||The species grows in south-eastern caatinga (inselberg) element, on gneissic inselbergs and rocks.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||10|
|Use and Trade:||The species is used as an ornamental in specialized collections.|
|Major Threat(s):||The major threat for this species is quarrying of the rock where it grows. It is also adversely affected by collection, deforestation, invasive species, fire and cattle trampling.|
|Conservation Actions:||The species does not occur in any protected areas. Protection of its habitat is strongly recommended.|
