He named it provisional as Trichocaulon hospitans but he never publish it. Later, in September 1929 Hans Herre collected it in Hellskloof. Gert Nel described this material as Trichocaulon columnare in 1933.

In 1985 John Lavranos and Mary Bellerue-Bleck published new genus Notechidnopsis with N. columnaris and N. tesselata. In 2002 Ulrich Meve and Sigrid Liede published new monotypic genus Richtersveldia with R. columnaris.
