salitrosis: v. v. et s. tn herb. meo et Hook., loc. cit.(Gillies) ; 
in prov. Santiago del Estero, in salitrosis (Tweedie, 1157). 
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
