5. WHITE SPRUCE 

 Cat Spruce 

 {Picea glauca (Moench) Voss) 



White spruce is confined in its natural distribution to the Adirondack*, 

 reaching its best development in the so-called "spruce flats," but ex- 

 tending also far up the mountain slopes. The wood is in great demand 

 for chemical pulp. Its attractive foliage makes it prized as an ornamen- 

 tal tree, for which purpose it is planted far south of its natural range. 



Bark — gray- 

 ish to pale red- 

 dish brown, 

 separating in 

 thin scales. 



T w i g s — 

 smooth., slen- 

 der, yellowish 

 brown in color. 

 Winter buds 

 small, blunt- 

 pointed, light 

 brown in color. 

 Leaves — nee- 

 dle-like, borne 

 singly and 



densely, crowd- 

 ed on twigs, 

 light shiny 



Branchlet and cone, natural size green 111 COLOl' 



when young, becoming blue green in color, y% inch long, 4-sided in cross 

 section, without stalk, remaining on the twig from eight to ten years. 



Fruit — a cone with very small stalk, pendant, from IV2 to 2^2 inches 

 Long, pale brown in color when ripe, maturing in one year. Cone scales 

 — thin, rounded, entire margined. Seeds — 2 under each scale, brown in
