The strong and flattened spines of this plant give it a peculiar 
character, which indicates an approach to the following remark- 
able species. The branchlets are about 4 inches in length, the 
primaiy spines inch long, gradually diminishing upwards; 
their secondary spines, in one, two, or three almost horizontally 
salient decussating pairs, are from 3 to 6 lines long, much flat- 
tened and spreading at their base, where they are 2 lines broad 
and half a line thick, all armed with a reddish, sharp, callous 
point ; they are of a greenish pallid hue. The flowers, in clus- 
tered fascicles, are nearly the size of those of C. intricata, and 
of the same pale colour ; the tube is more globose at the base, 
and much contracted in the middle, 2^ lines long, the diameter 
of its mouth 1^ line, and the reflected segments 1 line in length : 
the slender peduncles are 2 lines long. This plant, by mistake, 
is confounded with Discaria Americana in the ‘Botanical ]\Iis- 
cellany

This plant was raised in England many years since, and then 
erroneously supposed to be a hybrid, or a monstrosity of C. 
spinosa, and was described by Dr. Bindley under the name of 
C. Bictonensis. It is the most remarkable species of the genus, 
on account of its monstrous spines, which are flattened, and 
extend from one axil to another in cruciating and divaricating 
pairs : they are nearly an inch long and 3 to 6 lines broad at
