Aylostera pauciareolata description


The original description of Rebutia (Aylostera) pauciareolata was published in Kakteen und andere Sukkulenten 28(4): 77, 1977, the journal of the Deutsche Kakteen-Gesellschaft, by Friedrich Ritter. Further details were given in Ritter’s book Kakteen in Kakteen in Südamerika vol. 2 (1980).

Here is the text of the description of this species in the original Latin, but you should look up the original description for more details. The English translation below is my own.
