Aylostera albiflora description


The original description of Rebutia (Aylostera) albiflora was published in Taxon (1963) p. 29, the journal of the International Association for Plant Taxonomy, IAPT by Friedrich Ritter.

Here is an excerpt of the main points in Latin as published, with my own English translation below, but you should look up the original description for more details.
