Sulcorebutia canigueralii (Syn. Rebutia canigueralii)

I finally did get out and take some new pictures. They'll have more color in the summer, and of course there will be flowers! But without either, they're still rather impressive little plants.
This complex of plants can be very confusing, showing a large diversity of forms over a wide geographic area. As a result, there has been a large number of names given to what some now consider to be one species. However, I'm sticking with the more helpful and descriptive names. Tomorrow, Sulcorebutia pulchra (Syn: Rebutia canigueralii).

Enjoy your plants!
