Description

A mystery plant! “mariana” is the name of a Weingartia (Sulcorebutia), but this is an Aylostera. Karel Kníže named a plant Rebutia (Aylostera) mairanana, KK1803, subsequently written as R. mairanensis. Mairana is a village in Santa Cruz department, Bolivia. This is probably that plant, mis-named by a German nursery, but there is no field number.

From seeds sown in 2021 from our own plants.
