beneath each spine, between which is seen the squamose tuft 

 out of which the flowers sjiring. The flowers are of a deep rose 

 colour, with a white reflexed border, and are larger than the 

 other species of the genus ; the pedicel is 2 lines long ; the calyx 

 is tubular, not contracted in the middle, fleshy at base, 3 lines 

 long and 2 lines in diameter, the segments of the border being 

 in addition 1 line long and | line broad*.

This is very different in habit from the former, being of a 

 deep yellow hue, somewhat pubescent, with much shorter and 

 thicker spines and closer axils. The primary spines are l|-2 

 inches long, the secondary spines ^-| inch long, and 4 lines 

 apart, and the tertiary spinelets are 3 to 4 lines long, all form- 

 ing a dense entanglement; the leaves are channelled above, 

 about 2 lines long, 1 line broad, tapering into an almost obso- 

 lete sulcated petiole ; the pedicels are 2 lines long ; the tube of 

 the calyx is 3 lines, and the segments 1 line long : it is quite 

 cylindrical, and 2 lines in diameter; the filaments are only 

 ^ line in length, the anthers globose. The flowers much re- 

 semble those of the preceding species in size and form, but the 

 annular disk is placed nearer the base of the tube ; they are quite 

 glabrous.
