Description and meaning of the name
A horticultural form with a very dense, patterned covering of pale hairs. Cactus Art links its development to Tsutomu Onzuka in Japan in the 1970s. Patterns differ among plants and change during development. Ball, White Form, columnare and rib number describe additional features. Onzuka Kikko and Onzuka Fukuryu combine hair type with altered rib structure. [11-WWW]
