Thelocacatus bicolor

Mammillaria

Sunny Side Up - A fortunate mistake that resulted when I accidentally included a non-conformant image in a set of images for Helicon Focus. The bad image was way too bright.. Thelocactus hexaedrophorus.

Echinopsis "Spring Symphony"

Ariocarpus fissuratus

Notocactus (?)

Echinopsis "Cheetah"

Echinofossulocactus tricuspidatus - These have been taxonomically moved to Stenocactus. Mine prefer to be called by the original Echinofossulocactus. It's a way cooler name.
