This species has a fuscous hue, with short interlaced spinelets : 
the primary spines are 2 inches long; the secondary 8-10 lines, 
and 5 lines apart; the tertiary spinelets are 3 lines long, very 
stout, with a sharp point. The leaves are very caducous, and 
are wanting in the specimen I have seen, but they are described 
by Kunth. The flowers are small, of a reddish hue, many of 
them appear sterile, and soon fall off ; the segments of the border 
are nearly as long as the tube, each being about 1 line long ; and 
the tube is cylindrical, 1 line in diameter; the disk is seated 
near its base : the pedicel is only f line long in the flower, and 
2 lines in fruit. The 3-lohed capsule, supported on the cupular 
remnant of the calyx, is 2^ lines in diameter*.
