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 ai’e 2-2^ lines long, slender, the flowers being a line in 
length, and the same in diameter; the capsule is 1^ line diam. 
The specimens from Germain’s collection, distributed as the 
Rhamnus linearis, Clos, belong to this species *.
