Dr。 Engelmann observed a curious intermediate character in the origin
of the flowers of this species�察�the first ones of the season appearing in the
axils of the last tubercles of the preceding year�察 �while the later ones
develop from the axils of the first tubercles of the same season。The
specimen growing in Mo。 Bot。 Gard�察�in 1893 had 3 central spines�察�one or

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�
but the tubercles are much more slender and not thickened at base�察�all the
spines are more slender�察�the central hooked one is more reddish�察�and the
fruit is much shorter。
