Obregonia denegrii

This fabulous cactus is one of my favorites. It has dark green stem and the cristate form is much sought after by collectors. I have had the pleasure of finding species of these cacti at San Vicente, Tamaulipas, Mexico. They are very difficult to find.

Variegated forms of this cactus are now making their way to collectors. One can find partially variegated and complete variegated forms as in this picture. Variegated forms have to be grafted because of lack of chlorophyll.
