     The var。 valida was described by Dr。 Engelmann without having seen

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。
