The name of ftoribundum is ill applied to this very distinct 

 species, for it is generally very sparse of flowers, although Back's 

 specimen, like that collected by me at the Alto del Yeso, may 

 have presented more flowers than usual. It is of very straggling 

 growth, the tortuous branches spreading out at right angles : 

 the spines are generally J inch long, and slightly bent and 

 recurved; they are all covered with a whitish pubescent bark, 

 marked by reddish longitudinal lines, decurrent from the angles 

 of each cup-shaped node : the spines have many gemmiferous 

 axils ; the leaves are fasciculate in each closely approximate node, 

 are spathulately ovate, fleshy, covered with short, simple, and 

 glandular hairs, mixed together, and proceeding out of as many 

 whitish rugous spots; they are 2-2 4 lines long, j-1 line broad; 

 the flowers are solitary in each fascicle, | line long ; the calyx is 

 pubescent, tubular, 2 lines long, half-cleft into five rather equal, 

 lanceolate acute teeth, which are somewhat recurved at their 

 apex : the tube of the corolla is cylindrical, and slightly funnel- 

 shaped above, but constricted a little above the base, is 2 i to 3 

 lines long, and is covered with short glandular hairs ; the seg- 

 ments of the border are oblong, and I5 line long: the stamens 

 are inserted about the middle of the tube; the filaments are 

 hirsute at base, smooth above; the two shortest reach the 

 middle, the three longer attain the extremity of the segments : 

 the style is even longer : the corolla, as in other species of this 

 genus, breaks off" by a circumscissile line above its base, leaving 

 the ovary half surrounded by a cup-shaped process. In the spe- 

 cimen from El Alto del Yeso, the spines are fertile to the 

 extremity, the leafy fascicles being only 1 line apart : the berry 

 is globular, apiculated, IJ line diameter. The specimen from 

 Coquimbo agrees in all respects with the others, except that the 

 ramifications are more intricately branched and spinose ; the bark 

 is darker, more striated and pubescent, and the leaves are smaller ; 

 the axillary nodes, however, are equally approximate, and the 

 flowers are exactly similar in size and structure*.
