 g-enerally less than 1 ft.: branches himg". slt-nder, those below widely 

 spreading- and often drooping but with branchlets tending upward 

 forming an irregular oblong or broadly ovate head often as broad as 

 tall with slender, stiff spray. 



BARK — Thin, flaky, light grayish-brown broken into narrow flattish 

 pieces, loose at the ends. 



TAA'IGS — Slender. 1-2 mm. in thirkness, dark reddish-brown, often 

 zigzag, for the most part smooth and shining. LENTICELS — scattered,

 smaller and the bundle-scars are not sunken, the bud-scales are In 4 

 ranks and the staminate flowers are borne in catkins which are gener-
