SOUTH AMERICAN PLANTS. 135 



specimen often not more than 3 lines in length : this I col- 

 lected also on the Alto del Yeso as well as the Coral de Desa- 

 guadero in the same province*. 



ir. 7. confertifolium : here the leaves are broader, oblong, and 

 more glandularly pubescent, 4 to 6 lines long, 11 line broad; 

 the axils are closely approximated at the extremities of the 

 branchlets, so that the fascicles of leaves appear crowded : the 

 brauchlets issue from the branches at right angles, or some- 



downwards

prominent. I found this variety m the province oi 



it is the same as a specimen in Sir Wm. Hooker's herbarium 



collected by Dr. Gillies {L. Hookerianum, Gill. MSS.t). 



Var. 8. divaricatum : a variety greatly resembling the last in its 

 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 |. 



Var. e. affine : ramulis subvirgatis, strictis palhde pubescen- 



tibus, nodis axillaribus valde prominentibus ; foliis fascicu- 



latis, oblongis, utiinque acutis, rigidis, palhde flavescentibus, 



pUis brevibSs brachiatis fere stellatis pubescentibus ; floribus
