spreading branches and pale stem, with raised costate lines 

 decurrent from each margin of the cupular nodes ; the leaves 

 are similar in form, less dense, quite glabrous, with the excep- 

 tion of the younger leaves, which are slightly pubescent ; they 

 are 4 to 7 lines long, 1 to 2 lines broad ; the berry is globular, 

 of a crimson colour, and supported by the cup-shaped toothed 

 calyx. I found this growing abundantly in the Travesia or 

 desert tract of Mendoza*.

The leaves have a yellowish hue when dried ; they are from 5

 calyx IJ line long ; the tube of the corolla is 1| line long, thick, 

 and contracted at base, where it is surrounded by a densely 

 tomentose ring; the segments of the border are 2 lines long, 

 oblong, and extremely pubescent f.
