 Abies nigra, Poir. 



A small tree found in swamps and mountain woods. Branchlets 

 pubescent, foliage purplish glaucous ; cones small, ovate, in this 

 locality less than an inch in length, persistent, growing on the 

 branchlets, generally recurved, and frequently in clusters, purple 

 when young. June 2. 



var. rubra, Engelm. (Red Spruce.) 



' Differs from the type, in having darker and larger leaves ; larger, 

 bright red-brown cones, which (are borne nearer the tips of the 

 branchlets, and) are more readily deciduous after maturity."

 (./. Macoun.) 



2083. P. alba, Link. (White Spruce.) 

 Abies alba, Poir. 



A most beautiful forest tree, sometimes forming a steeple-like cone 

 over 100 feet in height. Branchlets glabrous ; leaves slenderer 

 than in 2082, of a much brighter green, or in a variety occurring 

 at Rockcliffe, of a beautiful glaucous white, almost equalling the 

 celebrated Colorado Blue Spruce (Picea pungens,) of the West. 

 Cones cylindrical, from 1-2 inches in length, pendulous from the 

 tips of small branchlets, deciduous, green when young, pale brown 

 when mature. 

 TSUGA, Carr. Hemlock. 

 2086 T. Canadensis, Carr. (Hemlock.) 



Abies Canadensis, Michx. 



A magnificent tree, whether viewed as the hoary giant which has 

 withstood the winter blasts of centuries, or the young tree which 

 lias not yet formed a trunk, when in spring as the young foliage is 

 pushing forth from the tips of the pendulous branchlets, and num- 

 berless slender twigs, it can only be likened to a living fountain, 

 every spray of which is tipped with golden green. Foliage dark 

 green above, silvery beneath.
