the stem, in the very much longer and stronger and black 
species, collected into fewer fascicles. The flower, as Mr. 
Mackie observes, is larger, the tube longer and slenderer, 
and clothed with much longer tufts of hairs. It is, in all - 
probability, a native of the same country as E. Eyriesit, 
namely Mexico. 
Descr. Stem subglobose, much depressed, umbilicated 
at the top, and deeply cut into about eleven very prominent, 
compressed, slightly undulated angles, which have five or 
six woolly tubercles, each giving rise to a fascicle of six to 
eight strong black spines, from half to nearly three quarters of 
an inch long. From one of these fascicles the flower springs, 
which is remarkably large in proportion to the size of the 
plant. The calycine tube is very long, a little enlarged 
upwards, brownish-green, scaly, each scale with a long tuft 
of slender, flaccid hairs. Petals spreading, white, oblong, 
much acuminated. Stamens numerous, included, white as 
well as the style and stigmas.
