Description and meaning of the name
Type B in Cactus Art is distinguished by irregular projections on and between ribs. Its appearance differs from the additional ribs of type A. The catalogue also lists combinations with nudum and variegata. Types A and B remain separate descriptive records, without recognition as botanical subspecies. [11-WWW]
