This species has an extensive range along the skirts of the 

 Cordillera; but I doubt its existence near the sea-coast, though 

 Bridges's specimens are referred to as from Valparaiso, that being 

 the place whence they were sent : this error of locality is frequent 

 among the specimens of Bridges and other collectors. Its range 

 extends as far to the southward as Concepcion, where it forms a 

 tree 18 feet in height, with a trunk 18 inches in diameter, the 

 wood being very durable, even in the ground ; for which reason 

 it is used in building the cottages of the natives : an infusion 

 of its bark is also employed there in the cure of ulcerous swellings. 

 I met with it on the eastern side of the Andes, where it forms a 

 pretty tree, with long, slender, pendent branches, with abundant 

 delicate foliage, and copious small white flowers. Its leaves, 

 with three parallel prominent nervures, are from 6-9 lines 

 long, 2-3 lines broad, on a slender petiole 1 line in length : the 

 pedicels are 2-2J lines long, slender, the flowers being a line in 

 length, and the same in diameter; the capsule is 1J line diam. 

 The specimens from Germain's collection, distributed as the 

 'Rhamnus linearis, Clos, belong to this species *.
