you may find laid down on the map, near the Uraguay River. 
Here I encountered a most severe shower of ice or hailstones, 
some of them measuring from 8 inches to a foot in circum- 
ference; the bark was stripped from the trees by the force 
with which they fell, and had a. gun been fired upwards 
among the trees loaded with large shot, it could not have 
done more damage." Mr. Tweedie’s plants appear to have 
been collected in nearly the same districts. 
We. shall divide our collections into three portions. I. 
Those of Extra-Tropical South America. - II. Those of 
Peru and some allied territories: and III. Those of the 
Islands of the Pacific. 
1. Extra- Tropical South America. n 
In this region we comprise the plants of our collections 
found in Chili, including the islands of Chiloe and Juan Fer- 
nandez, the Andes of Chili and of Mendoza, Mendoza with its 
plains or Pampas, and portions of San Juan de Cordova, as far 
as Buenos Ayres and the Banda Orientale. These, with the 
results of the labours of two excellent foreign botanists, MM. 
Bertero and Póppig, who are still zealously collecting in Chili, 
when they shall be made known, will, we hope, give a toler- 
able idea of the vegetation of the last-mentioned country, at 
least. From M. Bertero, indeed, we have received a beauti- 
ful collection of Juan Fernandez plants; but being without 
permission to publish them, and. as that able botanist intends 
to do so himself, we have. abstained from all notice of them, 
except in those cases wbere we possess the same plant from 
other sources ; and then we have felt that we should be doing 
M. Bertero a mahifest injustien were we not to take notice of 
his, often, previous discoveries, and were we not to adopt his- 
MS.* name, where such name was not Sinon noe 
other reasons objectionable. —
