AND THE ADJOINING TEEEITOEY. 215 



(No. 103, G. C). Sometimes improperly called Vinagrillo. 

 This species has not a tuberous root. My specimen is very 

 in complete. 



Celastbine^;. 

 Matte nvs Chilensis, 1>C. Valleys of the Upper Limay 

 and Chubat, in Patagonia (No. 59, G. C.). A small tree, rather 

 variable in habit. 



Rhahneje. 



Discaeia longispina, Hook. Sf Am. Common in the west and 

 south of the province of Buenos Ayres (No. 83, G. C). The 

 thick roots serve as fuel, and the flowers are sold in Buenos 

 Ayres. Further south, in Patagonia, the flowers of this (perhaps 

 a different ?) species give out an odious smell. J>. febrifuga, 

 Mart., is scarcely a distinct species. 



AnACAEDIACEJE. 



Duvatj a PKvECOX, Qriseb. A common and characteristic shrub 

 throughout North Patagonia (four specimens, Nos. 150-L53, 

 G. C). This forms a bush 5 or 6 feet in height. The Patagonian 

 Indians call the plant Berele and the fruit Yssgitz. The Arau- 

 caiyan name is Mitschi. There is another species, called Ahnec by 

 the Patagonians, a small tree, not more than 15 feet in height, 

 with broader leaves and larger fruits, from which the Indians pre- 

 pare a fermented drink. D. prtecox appears to be widely spread 

 and very variable ; I do not think that D. fasciculala, Griseb., 

 can be separated from it. 



Leguminosje. 

 Medtcago lttpulina, L. ? Yery young, but undoubted. 

 Bahia Blanca (No. 105, G. C). Introduced from Europe with 

 other species of the same genus. 



Glycybbhiza asteagalina, Hook. Sf Am. Appears to have 

 descended from the Cordillera along the valleys of the Chubat, Eio 

 Negro, and Rio Colorado (No. 162, G. C). This, which has blue 

 flowers and glutinous leaves, flowers in spring (October to 

 December). The Spanish name is Curuzu ; the Araucanian name 

 l&ilpi. A decoction of the resinous leaves is administered to 

 women after childbirth. 



Adesmia geisea, BooTc.fil. Bahia Blanca and south of the 

 province of Buenos Ayres. Common, especially in sandy ground
