146 DOUGLAS FIR, SPRUCE 



twigs expanded in the horizontal plane, the latter bearing 

 crowded linear leaves arranged in a pectinate 1 , apparently 

 distichous, manner; leaves silvery below. Cones blunt 

 with numerous thin closely imbricated scales. Crown 

 pyramidal-pointed, twigs opposite (see also p. 156). 



Many other species of Abies are met with in culture. 

 Most of them have silvery or bluish-glaucous foliage, and 

 all are distinguished from the Spruces (Picea) by the erect 

 cones. 



/~7 /~7 Spray of the lower branches more or less 



pendent right and left of the sweeping 



branches of the pseudo -whorls. Cones 



pendent and falling as a whole. 



Leaves resembling those of Abies but 



not so decidedly combed right and 



left; branches not so decidedly in 



pseudo-whorls; cones with prominently 



exserted three-pointed bracts protruding 



from between the scales. 



Pseudotsuga Douglasii, Carr. Douglas Fir (Fig. 62). 

 Tall North American Fir attaining 150 200 feet on the 

 Pacific coast, with red-brown scaly fissured bark, and 

 slender sweeping branches with upturned tips, bearing 

 crowded spray with linear leaves all round, and often 

 curved forwards. Remarkably feathery habit. 



Leaves acicular-quadrangular ; cones 

 sub-cylindric with no projecting barren 

 scales. 



Picea excelsa, L. Spruce (Fig. 62). General habit, 

 narrow elongated, pyramidal-pointed, resembling that of 

 Silver Fir, and attaining 100 150 feet, but crown more 



1 [The term "pectinate" (also represented in the specific name of 

 Abies pectinata] here does not refer to the shape of the leaves, but is 

 descriptive of their arrangement in a double comb-like pseudo-distichous 

 pattern.]
