     In all references to the fruit of this species it is described as ;oval and 

green�察─  �except   in   Ives   Report�察  �where   Dr。   Engelmann   describes   its   real 

character as the ordinary fruit of Eumamillaria。The immature fruit is ;oval 

and   green�察─  �but   with   maturity   it   becomes   clavate   and   scarlet。The   Utah 

specimens      of   Parry   show    an   exceptional    character    in  their  30   to  33 

scabrous radial spines�察�but otherwise they are quite normal。M。 microcarpa 

Engelm。�察�Emory's Rep。 156。 f。 3�察�should be dropped as a synonym of this 

species�察�at least as to figure and description。 In all probability C。grahami is 

one of the forms of the Mexican C。 schelhasii ��Pfeiff。��。Except that in C。 

grahami the radial spines are apt to be more numerous and longer�察�and the 

centrals much darker�察�and in C。 schelhasii the 3 centrals seem to be always 

present     and     sometimes      all   hooked�察    �the    descriptions     suggest     no 

difference。In     the  absence     of  authentic   specimens      of  the  latter  species�察�

     The   capillary   radials   give   the   plant   a   white´woolly   appearance。The 

younger spines at the vertex are erect and tufted。It resembles C。 grahami�察�

spines are more slender�察�the central hooked one is more reddish�察�and the 

fruit is much shorter。
