PINUS STROBUS, L. 5 



branchlets and season's shoots slender ; head cone-shaped, 

 broad at the base, clothed with soft, delicate, bluish-green 

 foliage ; roots running horizontally near the surface, taking 

 firm hold in rocky situations, extremely durable when ex- 

 posed. 



Bark. On trunks of old trees thick, shallow-channeled, 

 broad-ridged; on stems of young trees and upon branches 

 smooth, greenish ; season's shoots at first rusty -scurfy or 

 puberulent, in late autumn becoming smooth and light russet 

 brown. 



Winter Buds and Leaves. Leading branch-buds \-^ inch 

 long, oblong or ovate-oblong, sharp-pointed ; scales yellowish- 

 brown. 



Foliage leaves in clusters of five, slender, 3-5 inches long, 

 soft bluish-green, needle-shaped, 3-sided, mucronate, each with 

 a single fibrovascular bundle, sessile- 

 Inflorescence. June. Sterile flowers at the base of the 

 season's shoots, in clusters, each flower about one inch long, 

 oval, light brown ; stamens numerous ; connectives scale-like : 

 fertile flowers near the terminal bud of the season's shoots, 

 long-stalked, cylindrical ; scales pink-margined. 



Fruit. Cones, 4-6 inches long, short-stalked, narrow-cylin- 

 drical, often curved, finally pendent, green, maturing the 

 second year ; scales rather loose, scarcely thickened at the 

 apex, not spiny ; seeds winged, smooth. 



Horticultural Value. Hardy throughout New England ; free 

 from disease ; grows well in almost any soil, but prefers a 

 light fertile loam ; in open ground retains its lower branches 

 for many years. Good plants, grown from seed, are usually 

 readily obtainable in nurseries ; small collected plants from 

 open ground can be moved in sods with little risk. 



Several horticultural forms are occasionally cultivated which 

 are distinguished by variations in foliage, trailing branches, 

 dense and rounded heads, and dwarfed or cylindrical habits 

 of growth.
