The var。 valida was described by Dr。 Engelmann without having seen
C。 scheerii�察 �the only knowledge of that species being obtained from the
description of Prince Salm´Dyck in Cact。 Hort。 Dyck。�察 �which seemed to
indicate a smaller form�察�with fewer spines than the Texan form。However�察�
when visiting the collections of Prince Salm´Dyck�察�Dr。 Engelmann found
original specimens of C。 scheerii which were exactly his var。 valida。So far
as collections show the Texan form seems to be more robust than the
Mexican�察�but the material is too scanty to justify such a generalization。Dr。
Engelmann speaks of this species as ;a stately plant�察�by far the largest�察�of
the northern Mamillariae;Its tubercles are bright green and in beautiful
contrast with the showy yellow spines。

Even in the absence of the type I have ventured to refer Mamillaria
pectinata Engelm。 to this species。Dr。 Engelmann had concluded that the
two were ;not sufficiently distinct�察─ �and the examination of Mexican
forms which pass as C。 radians abundantly confirms this
conclusion。Besides�察 �every character in the original description of C。
radians applies exactly to these Mexican plants and to our Texan
specimens as well。Aside from the fact that the Mexican spe
