AND THE ADJOINING TERRITORY. 211 



open country interspersed with a considerable variety of shrubs, 

 in great part evergreen, reminding one of the aspect of many parts 

 of the Mediterranean region. 



Lastly, with regard to the asserted paucity of subtropical forma 

 in the regions bordering on the lower course of the Parana and 

 the Uruguay, it seems to me that, as compared with districts in 

 the same latitude north of the equator, whether in North America 

 or North Africa, the statement is quite opposed to the facts. Of 

 the tree- vegetation nearly all are subtropical forms. Of the 

 bushes the majority seem to belong to types characteristic of 

 temperate South America, most of them common to the east and 

 west sides of the Andes, while the herbaceous vegetation exhibits 

 about an equal proportion of elements characteristic of the sub- 

 tropical and the South-temperate American floras. With refer- 

 ence to this subject much information is to be found in a paper 

 by Sir Charles F. Bunbury, in the 21st volume of the ' Trans- 

 actions of the Linnean Society,' lately reprinted, with additions, 

 for private circulation, along with other valuable papers by the 

 same author. 



It may be well to state that all the information contained in 

 the following list respecting the habitats, the local names, and the 

 uses of the plants enumerated is derived from M. Claraz. For 

 the botanical matter alone I am responsible. 



List of Plants collected in North Patagonia and South Part of the 

 Province of Buenos Ayres by M. Georges Claraz. 

 The species marked with an asterisk probably do not extend 

 to Patagonia. 



BeRBERIDEjE. 



Berberis nETEROPHTLLA, Juss. ? A bush 4 to 5 feet high, 

 common in Patagonia. Its northern limit is about halfway 

 between the Eio Negro and the Chubat (No. 147, G. C). The 

 Struthious bird, Mhea Darwinii, Gould, is very fond of the 

 berries, but these give a disagreeable taste to the flesh. 



The Patagonian Indian name for the plant is Gayauhhia, and 

 for the berries Khalgo. The specimen is a Bmall incomplete 

 fragment, and the determination uncertain. The plant may be 

 undescribed. 



PAPAVERACEiE. 



Fumaria capreoiata, L., var. Common about Buenos Ayres 

 and further south ; doubtless introduced from Europe (No. 157, 

 G. C).
