Linnsean Society). In habit it greatly resembles some of the 
species of Discaiia, for wbieh, at first sight, it might be mistaken. 
Its primary spines are very slender, almost acicular, of a pale 
green eolom’, pubescent, and about 2 inches long ; the secondary 
spines, still more slender, are from 4 to 9 lines in length ; the 
tertiary spinelets are only a line long : its filiform peduncles are 
line long, the veiy slender tube of the calyx, including the 
segments, is 2 lines long, the tube being j hne in diameter*.

The general habit and appearance of this plant are like those 
of C. spinosa, Lam., but its flowers are much smaller, its stamens 
mueh longer, and ostensibly exserted : its armature is stouter, 
the primary spines are about 2 inches long, the secondary ones 
6 to 9 lines long, diminishing upwards, and 4 to 5 lines apart ; 
the flowers are numerous, frequently as many as eight from each 
spine : the pedicels are slender, 2 lines long ; the length of the 
tube is 1| line, and of the segments 1 hue, its diameter half a 
line ; the fllaments are erect, half the length of the segments ; 
the style is exserted, and is deeply bullated or torulose all over 
its surface t-
