     The plants densely covered above with delicate ashy´gray spines and 

with naked tuberculate base are readily recognized。It still remains an open 

question whether the flowers are developed from the axils of tubercles of 

the same season or the last ones of the preceding season。Dr。 Engelmann 

inclined to the latter view�察�as all the other characters of the plant associate 

it   with   the  ;lateral´flowered;       species�察  �and    in  the  absence     of  definite 

observation we have retained it there。If the nearly central flowers indicate 

that they are produced from growth of the same season the species would 

seem  to   be   allied   to   Coryphantha�察  �in   which   group   its   small   flowers   and 

small tubercles would be anomalous。

     It is a question whether this variety does not merely represent an older 

and better developed plant than those upon which the species is based。Mr。 

Harry I。 Budd�察�who has made extensive collections of Texan and Mexican 

Cacti for the market�察�reports that it is impossible to separate sharply the 

variety from the species in the field�察�and regards the difference merely as 

one   of   age。Unfortunately�察  �only   living   material   of   the   species   could   be 

examined�察�but its characters seem well sustained even in the most vigorous 

plants�察�some of which reach the size of the variety。Through this variety the 

species is brought very near the following�此�

     Dr。   Engelmann   calls   attention   to   the   fact   that   this   species   is   closely 

allied to the Mexican C。 zephranthoides ��Scheidw。���察�but in the absence of 

material   representing   the   latter   species   no   comparison   can   be   made。In 

descriptions of the Mexican species the differently colored flowers and the 

much   longer   spines   suggest   differences   that   an   examination   of   fruit   and 

seed characters may still further emphasize。
