 The primary spines or branchlets are 2-3 inches long, the se- 

 condary spines are 8-10 lines long and 3 lines apart, the ter- 

 tiary spinelets are 4—5 lines in length and 2 lines apart; the 

 secondary spines, often opposite, are frequently ternate; the 

 pedicels are 2 lines long; the tube of the calyx, which is cylin- 

 di'ical and somewhat swollen at base, is 2j lines, and the seg- 

 ments li line long and | line diameter; the filaments are erect, 

 and I line long*.

This is a very distinct species, with stout and very straight 

 branchlets, 8 to 18 inches long, or perhaps longer, quite terete, 

 pruinose, or sparsely tomentose; the primaiy spines, frequently 

 ternate and very spreading, are scarcely longer than the inter- 

 nodes, which, together with their very divaricate spinelets, give 

 to the branches an interrupted spicate appearance. The ramal 

 internodes are | inch apart, the primary spines are 1 inch long, 

 the secondary spines are | inch long and 2 lines apart, and 

 the tertiary spinelets are 2 to 3 lines long; the leaves are 

 suborbicular, broadly emarginate at the summit, and mucronate 

 with 2 or 3 teeth on each margin : the petiole is seated in the 

 sinus of a bidentate stipule. The flowers are numerous, and 

 densely aggregated, owing to the very close proximity of the 

 axils, so that the entire branch appears a full-flowered spike : 

 the pedicels are somewhat more than a line long, the cylindrical 

 tube of the calyx is 1^ to 2 lines, and its segments f to 1 line 

 in length, its diameter being i or | line ; the flowers are pale 

 and membranaceousf.
