Rebutia (Aylostera) schatzliana was first described by Walter Rausch in Kakteen und andere Sukkulenten 26(11): p.p. 244 – 245, the journal of the Deutsche Kakteen-Gesellschaft, in 1975.

The description is reproduced here in the original Latin, and a note in German, together with my own translations in English. You should look up the original for more details, including a colour photograph.

Additional notes

Diese Pflänzchen gehören zur Aylostera-Gruppe um Rebutia heliosa/albopectinata, zeigen jedoch die zierlichsten Formen der ganzen Gruppe. Die meist weniger als 1 cm großen Pflänzchen sind dicht mit kurzen, borstigen Dornen bedeckt, die oft zusätzlich bewimpert sind, wie z. B. Sulcorebutia arenacea oder alba. Ebenso kleiner ist die Blüte, die dafür mehr behaart und beborstet ist. Ich benenne diese Formen nach dem verdienstvollen Leiter des Botanischen Gartens der Stadt Linz, Stefan Schatzl.

English translation

Radial spines 17-19, close-fitting, comb-like, 1-2 mm long, glassy white to honey-coloured, rough, no central spines or rarely 1, honey-coloured.

Type: Rausch 640, deposited in the Municipal Succulent Collection of Zurich, Switzerland.

These little plants belong to the Aylostera group, particularly Rebutia heliosa/albopectinata, but are the most delicate forms of the whole group. The mostly less than 1 cm plants are densely covered with short, bristly spines, which are often additionally ciliated, like for example Sulcorebutia arenacea or alba. The flower is just as small, which is hairy and bristled. I name these forms after the meritorious director of the botanical garden of the city of Linz, Stefan Schatzl.
