Aylostera

The genus Aylostera was formerly included in Rebutia. Mosti et al. (2011) have split the two genera based on DNA studies. A visible difference between the two is that Aylostera has flowers which bear hairs or bristles on the stalks, while Rebutia has flowers with naked, hairless stalks.

Aylostera is further divided into two sub-genera: Mosti et al. include Aylostera with 49 species and Mediolobivia Rowley with 59 species. In addition, there have been some new discoveries not accounted for in the study (e.g. A. malochii, described in 2009).

Look through the Aylostera gallery.

As with all of the genera in the National Collection, there are quite a few plants for which the name hasn’t yet been decided or given, or names not accepted. A few of these are shown here.

Hybrid plants are not often found for sale; many Aylosteras are self-fertile.
