I found this plant growing near Corocorto, a village 130 

 miles east of Mendoza, in a swampy saline district, where it 

 attains a height of 4 or 5 feet ; it is much branched, with 

 straightish, rather spreading or ascending branchlets, which 

 are polished, glabrous, of a reddish colour, slender and sub- 

 striated. The axils are 3-5 lines apart ; the leaves 9-15 lines
