Description
Thelocactus bicolorSN|3420]]SN|3420]] cv. inermis is a very distintive spineless form. It not only lacks spines but it also has odd fringed flowers often developing in pairs (or even more numerous) from the same areole. The frequent development of flowers buds in groups from the same areole and the nude appearance make this plant very different from the spiny standard Thelocactus bicolorSN|3420]]SN|3420]]. At the first glance it is really difficult to say that it is a Thelocactus.
