For him it simply was an insufficiently known species which needed further investigation but not a hybrid. marchandii as a natural hybrid nor did he suggest this parentage, he merely noted the similarity of the apparently rare hybrid found at Holgat River. x marchandii - see G.Rowley, Crassula, a Grower’s Guide,131, 2003 and Illustrated Handbook of Succulent Plants, 2003. These comments have led some to believe that Tölken “suggested” C. as only single specimens were found in populations of these species.” In Flora of Southern Africa 14: 229, 1985, he reiterated this comment, but added that they were “interpreted as hybrids. plegmatoides as both these species occur in the area.” , but they probably represent hybrids between C. marchandii, were collected in the Holgat River. “A few plants, very similar to those described as C. marchandii as a “species insufficiently known”. In his thesis, A revision of the genus Crassula in southern Africa, 557, 1977, Tölken listed C. Rauh, not particularly interested in crassulas passed it to the German Crassula expert Friedrich in München who, after having seen its flowers, described it in 1974, apparently ignoring that Hutchison had intended to name it for Max Otzen. sent a plant to Rauh (hence the pseudo-Rauh-number). It is much more likely that it was Paul Hutchison who was in contact with Werner Rauh in Heidelberg who is responsible for its arrival in Germany i.e. It is not reported that the plant had ever been imported in Germany directly from South Africa. However in California the plant was propagated and ISI could offer it in 1970 to a wider public. He sent it to California, among others to Paul Hutchison who named it for its collector > Crassula otzenii but never got around to describe and publish it properly.Commercial collecting was a daily occurrence at that time, so that very likely the plant was extinct at its type locality already before the middle of the 20th century. The plant had been collected by Max Otzen (1871 - 1947), a German who came to South Africa in the 1880's. Otzen at Knersvlakte, Vanrhynsdorp S.A."ġ.
