Cultivation: Easy to grow and remains quite a small plant.

recommended reading: the cactus file handbook - Rebutia written by John Pilbeam.

Comments:
the image above is the best I can do as the "type plant" things are so complicated that I could well be wrong.


Pilbeam in his book "the cactus file handbook - Rebutia" lists 21 different "forms" without comment as to being subspecies, forms, ect but refers to CITES referring to the 21 varieties. There could be whole books written on this plant "Rebutia pygmaea" however greater minds than mine have failed to agree on the status of the various plants, so who am I to comment?

I have many of the plants that fall into the remit of "Rebutia Pygmaea" and will attempt to illustrate the species in pictorial form here.

This is by no means a comprehensive list ........

I could continue to illustrate Rebutia pygmaea, but I have the feeling that you begin to get the message, that things are somewhat confused .............just to add to the mix,........genetic information may reveal that the Rebutia complex in which Rebutia pygmaea exists may well fall into the category of mediolobivia, :?

My remit as a contributor does not allow me to comment on the genetic aspirations of individual plants :? ......so I leave it to the I individual reader to draw their own conclusions
