We heartily wish all species of Cactaceous plants were as readily 
distinguished, and as easily defined in words, as is the present 
remarkably fine and handsome one :—remarkable in the very 
prominent ridges, the large and regularly arranged spines, the 
central one very long, flattened, and hooked at the end, and 
handsome in the size and colouring of its flowers, both in the 
bud and when fully expanded. It is a native of Mexico, and 
appears to have been introduced to our collections by M. Galeotti. 
It flowers with us in the Cactus-house in July. 
Dzscr. Our flowering specimen is nearly globose, and almost 
a span high, deeply furrowed with about thirteen promment, 
moderately acute ridges, whose edge is waved by the projecting 
tubercles in which the areole are slightly sunk. These creole 
are large, oblong, lined with short, dense, dark-coloured wool, 
from which proceed about twelve or fourteen long and strong 
spines, bright red when young, afterwards brownish-grey, tinged 
with red, especially at the base; most of them are radiately 
spreading, the outer ones the slenderest, the central one 1s 
remarkably long, four inches in length, flattened, deflexed, and 
curved into a hook at the extremity. /Vowers large, handsome, 
between three and four inches long, and as broad from tip to tip 
of the petals. Calyx-tube dark green, studded with roundish scales, .
