     Dr。 Engelmann regarded this species as possibly only a variety of C。 

heyderi�察    �to   which     it  is  certainly    very    closely    allied   through    var。 

hemisphaerica�察�but   the different tubercles and   fewer stouter  spines  serve 

so well to distinguish it that it seems best to retain its specific rank。 

     In reference to the citation of the original description an explanation 

seems necessary�察�which will apply to numerous similar cases。The Pacif。 R。 

Rep。 iv。 27 ��1856���察�Syn。 Cact。 263 ��1858���察�and Cact。 Mex。 Bound。 9 ��1859���察�

have each been cited as the original publication。The confusion has arisen 

from the fact that in both the publications of 1856 the description in the 

Rep。   Mex。   Bound。   is   referred   to�察  �and   in   that   report   the   plant   is   fully 

described as ;sp。  nov。;However�察�the   publication of   the Boundary  Report 

was long delayed on account of the preparation of the plates�察�and in the 

meantime   both   the   publications   of   1856   had   appeared�察  �in   each   one   of 

which   the   species   is   distinctly   characterized   and   reference   made   to   the 

description     in  the   forthcoming     Boundary   Report。   As   between   the       two 

publications      of  1856    the  Syn。   Cact。   ��Proc。   Amer。     Acad。iii。   259��   was

     So far as can be discovered�察�this species has not been collected since 

the original Wislizenus   collection   of   1846´47。The   plants   were   cultivated 

by Dr。 Engelmann and made to bloom�察�showing the flowers to be larger 

and darker colored than in the rest of the group�察�from which the species 

also differs in its more robust habit�察�its very unequal radial spines�察�and the 

occasional occurrence of two centrals。

     The variations observed in this species do not seem sufficient for the 

establishment of varieties。The type form seems to have been globose�察�with 

4 radial spines and a stout central one。The depressed forms with 6 radials 

and   a   more   slender   central   represent   var。   spinosior   Lem。   ��M。   depressa
