ATRIPLEX L. 

 A. LAMPA Gill. Macl., p. 364. 



A characteristic steppe-bush 1.5-2 m. high, very common in N. Pata- 

 gonia, for instance along Rio Limay and Rio Negro and in the northern 

 section of the Patagonian east coast. 



It alone, or in company with other steppe-bushes, covers large parts of 

 the N. Patagonian steppe.

 U. Stbg. Macl., p. 368.

 Stbg. 



P. 367 : 



S. PATAGONICA (Moq.) Benth.

SALICORNIA L. 

 S. CORTICOSA Meyer. Macl., p. 369. 



According to Spegazzini, this species is very varying. In Nov. Add. 

 Flor. Patag., Ill, p. 154, he cites the three following forms: typica, nach- 

 tigalii and procitmbens, the last being identical with Salicornia corticosa 

 Meyer var. nachtigalii Nied. Salicornia bergii Lor. et Nied. is probably 

 identical with the present species.
