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.
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.
