Aylostera sp. “ruberrina” AVF38

A plant which was listed on some Czech nurseries as Mediolobiva pectinata var. ruberinna, Mediolobivia ruberrina, or Rebutia ruberrina and the Alberto Vojtěch Frič number AVF38; this would have been collected before Frič’s death in 1944. I have not found any location data for this plant.

Presumably the name “ruberrina” is in reference to the areoles which are prominently covered in reddish-brown wool.
