Xerophyte

A small genus of two species, Neowerdermannia is a genus of spiny globose plants which are very similar to the genus Gymnocalycium. Flowers are bourne near the apex and have naked floral tubes with scales - eiter white or pink. The fruits are globose and dehiscent.The body features ribs which are not clearly defined and broken into rather pronounced tubercles. Areoles are small at the top of the tubercles (not the ends) and give rise to as many as 20 stout spines which may be curved or even hooked. The plants in this genus are found in Argentina, Bolivia, Chile, and Peru, though apparently not in great numbers. It is even more scarce in cultivation and grown by enthusiasts, but not commercially.
