Rebutia pygmaea has a diversity of forms of varying taxonomic significance. This one is sometimes treated as a poorly differentiated entity within R. pygmaea var. diersiana The Llifle encyclopedia says: "Origin and Habitat: Mal Paso, PotosÃ, Bolivia. Altitude: Around 3600-4000 metres above sea level. Habitat: It is found in high, dry, rocky grasslands in valleys and rocky slopes of the Andes in fully exposed sites. Inhabitants must be very rugged in order to tolerate such extremes in exposure. Rebutia rutiliflora is such a robust individual. Description: Rebutia rutiliflora is one of the many geographical forms of the extremely variable Rebutia pygmaea. It has bright orange flowers. Habit: It is a small geophyte cactus, with a heavy tap root that may exceed the size of the plant above soil level. Solitary or clustering and barely rising above ground level. |
