3. DOUGLAS FIB. 

 Pseudotsuga Douylasii (Carr.). Abietineee. 



Very tall tree, but often irregular in this country. 

 The periderm and scaly bark haye a general resemblance 

 to those of the Spruce. 



Buds small, terminal ; few lateral. 



Leaves deep green, flattened, acicular, pointed, 

 isolated, curved forwards, and arranged all round the 

 twigs. 



Female cones terminal, rather small, pendulous, fall- 

 ing as a whole. The barren scales project with three 

 long teeth far beyond the sinuously rounded edges of 

 the ovuliferous scales. 



Wood rosy red, knotty, somewhat resembling that of 

 the Larch, with sharply-marked annual rings and small 

 resin-ducts. 



Seed trigonal, with an obliquely oval wing. Cotyle- 

 dons 5 to 7, triangular in section, and sharply pointed. 



4. SCOTCH PINE. 

 Pinus sylvestris (L.). Abietineee. 



Large tree, with rounded crown in the open; pyra- 

 midal when young. Very variable. 



Cortex of young branches green, passing into orange ; 

 bark red-brown, with large, thick, deeply-fissured 

 scales. 



Buds long and cylindrical in spring, and covered 

 with the short twigs. Lateral buds flank the terminal 

 one.
