Chron., xxv., pp. 652-654, illustrated ; also reprinted.) 
There are two species of Larix in Northwestern America, 
L. occidentalis, Nutt., discovered by Douglass in 1826 on the 
Columbia River, and referred by Hooker to Z. Americana, from 
_ which it was distinguished by Nuttall. This is a very large tree, 
reaching 200 feet in height, and was first introduced into cultiva- 
tion in 1880, when Mr. Watson sent seedlings to the Arnold 
Arboretum. The second species, Z. Lyallii, Parlatore, is a rare 
and local tree, discovered by Dr. Lyall during the British 
Boundary Survey of 1858-61, and recently detected by Mr. 
Brandegee at the timber line on Mt. Stewart, where it was alow, 
stunted tree, associated with Pius albicaulis and Tsuga Patton- 
tana. Beautiful figures of the two species, drawn by Mr. Faxon, 
illustrate Mr. Sargent’s paper.
