ARBORETUM AND FRUTICETUM. 



'ART III 



rockv hanks of the Spokan river. Discovered by Douglas, and intro- 

 duced in 1 VJ I . 



Description, AY-. A resinous tree, with 

 brownish-coloured bark. Leaves in fives, 

 triquetrous, obtuse; bieanaliculate above, 

 carinate below, with a blunt elevated line ; 

 obsoletelv crenulated on the margin ; 

 snioothisn, glaneous green; 1 \ in. to 3 in. 

 lomz. Sheaths imbricated with elliptic-ob- 

 long, obtuse, thinly membranaceous, loose, 

 bright brown scales, quickly falling oft'. 

 C ones cylindrical, smooth, 6 in. to 8 in. 

 long, generally in whorls ; scales spathn- 

 late, apiculate ; slightly convex beneath, dark 

 ash-yellow. Seeds oval, with a crustaceous 

 testa; wing hatchet-shaped, obtuse, striated, 

 dull yellow, shining. (Lawi.) Except in 

 its much shorter and smoother leaves, this 

 species differs but little from P. Strobus, of 

 which it may prove to be only a variety; 

 but, until an opportunity occurs of examin- 

 ing the male catkins, and ascertaining other particulars, it is considered best 

 to keep it distinct. Judging from the appearance of the specimens sent 

 home by Douglas, the tree must abound in resin. The plant in the Horti- 

 cultural Society's Garden is only a few inches high. Among Douglas's spe- 

 cimens, there is a variety with red cones, from which no plants have yet 

 been raised.

America, on .-watupy ground near 



tie sea coast; and, abundantly, near 



(ape Disappointment and Cape 



Lookout. Dried specimens, with 



cones, were sent home in lV.~i-i>-7 ; 



but no plants, have been raised from 



them. No remarks respecting this 



species, as far as we have been able
