 perennial, succulent, |-2 ft. high, -J-IJ in. thick, simple or branching 

 at the base, cylindric, with rather lars^e diamond-shaped tessellations, 

 scarcely forming tubercles, glabrous. Leaves in a small tuft at the tips 

 or spaced along the upper part of the stems, |-2J in. long, J-l| in. 

 broad, obovate, oVjtuse or subacute, tapering below to a subsessile base 

 or into a very short broad petiole, finely crisped-crenulate or scabrous 

 on the margins, somewhat harshly puberulous on both sides, green, 

 falling before the flowers and fruit fully develop, or persistent under 

 cultivation. Stipules of 0-5 minute spines, J-f lin. long, around the 

 lower side of the base of the leaf, evanescent. CVmes at first 4-5 lin. 

 long with 1 involucre, ultimately \-\ in. long and £ in. broad with 

 8 involucres, axillary, nodding, after the fall of the leaves forming a 

 small cluster at the apex of the stem, but in cultivated plants some- 

 times spaced along the stem ; peduncles 1-3 lin. long, stout, branches 

 of the cyme very much shorter. Bract-cup oblique, 8-8J lin. long,
