Henry and F cod's The Dougla.o Firt* 



The Douglas spruce has always been regarded as a variable 

 species and many have wondered if not more than one species 

 have been included under that name. It is therefore very inter- 

 esting to know that this problem has been taken up lately and 

 been attacked from more than one standpoint, the gross anatomy 

 of the branches, leaves and fruit, but a comparison has also been 

 made as to the difference in odor, minute anatomy of the leaves 

 and chemical composition of the oil distilled from the leaves. 



The authors admit three species and one variety native to 

 North America and four species native to China and Japan. The 

 North American species, which interest us most, are distinguished 

 as follows: 



" r. P. Douglasii Carrierre. Pacific coast region of North 

 America. Branchlets pubescent. Leaves thin, flat beneath, with 

 pineapple odor. Cones 3 to 4 inches long, with straight erect 

 bracts. 



" var. cacsia Schwerin. Northern Rocky Mountains. This 

 differs from the type in the glabrous branchlets, the thicker 

 needles and smaller cones, 2 J/2 inches long.
