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*.

 pilis brevibus brachiatis fere stellatis pubescentibus ; floribus

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

 to 7 lines long, \~ to If line broad, the petiole being almost 

 obsolete : the peduncle is erect, 2 lines long, the very pubescent 

 calyx 1~ 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 pubescentf.

This plant is of straggling bushy habit, and grows abundantly 

 in the moist pasturages to the southward of Mendoza. It much
