126 PATAGONIAN EXPEDITIONS: BOTANY. 



BERBERIS EMPETRIFOLIA Lam. Mad, p. 416. 



Through Patagonia in its whole length, viz., in the pre-andine district 

 and the steppe district near the Cordillera. 



B. HETEROPHYLLA Juss., Califate. Macl., p. 417. 



Very common, at least in South and Central Patagonia, viz., in the 

 whole steppe district. The shrubs vary, often man-high, produce 

 (branches as well as roots) the most valuable firing outside the forest 

 district. 



B. ILICIFOLIA Forst. Macl., p. 417. 

 Also in W. Patagonia, Rio Aysen. 



B. INERMIS Pers. Macl., p. 417. 

 Should be deleted, being identical with B. microphylla Forst. 



B. MICROPHYLLA Forst. Macl., p. 417. 

 Also in W. and N. W. Patagonia ; S. Chili. 



B. PEARCEI Phil. Macl., p. 418. 

 Also in N. W. Patagonia, Rio Puelo. 



Add Macl., p. 418: 



B. ROTUNDIFOLIA Poepp. 



N. W. Patagonia, Rio Puelo; Chiloe I.; S. Chili. 



B. RUSCIFOLIA Lam. Macl., p. 418. 



Should be deleted ; not known from our district. The specimen deter- 

 mined as B. ruscifolia actually belongs to Berberis ilicifolia Forst. 



B. VIRGATA Ruiz et Pav. Macl., p. 418. 



Should be struck out. This species belongs to the flora of Peru, but is 

 not known from our district. 



The plant reproduced in Plate XV, to which Macloskie refers, repre- 

 sents no Berberis, but Escallonia virgata Pers.
