This handsome Cactus has long been cultivated at Kew, under 
the name here given, and it is said by the authority for that name 
to be a native of Tampico. It is of a nearly globose form and 
remarkable for its large tubercles, which are obscurely s^-sided, 
whence the specific appellation is derived. Lemaire further says 
that the direction of these tubercles is in a double senes, vertical 
and spiral; the double series in our plant is not an evident 
character, though it may sometimes be discerned. Its flowering 
season is June, and the blossoms are lively and pretty. 
Descr. Entire plant subglobose or turbinate, flattened at the 
top, divided into large six-sided depressed mammillse, the ower 
and older part compressed and brown, the rest of a glaucous m , 
the tubercles or mammillae arrayed in spiral fines, wit eep 
furrows between them. The areola is indicated } a mear 
depression in the disc of the tubercle, from which t e c us er 
of spines springs. The spines are from four to seven m num er, 
varying in length from half an inch to nearly an me , e 
central one is the longest and strongest: all of them are rather 
stout, of a reddish-brown, subulate, more or less spreading. 
Flowers 2—3 from the crown of the plant. Calyx ^adua y
