glaucous-green color, and very pendu- 
lous. Cones 6 to 9 in. long, and 2 in.

called the Weeping Fir.

ciduous sheaths. Cones 12 to 18 in.

ally tapering to a point, on stalks 3 in. 
long, brown and pendulous when ripe, 
without resin; seeds large, oval, nearly 
1 in. long, edible. A very large tree 
(100 to 300 ft. high in California and 
northward), and seemingly hardy and

been common throughout, but is’ get- 
ting scarce on account of its consump- 
tion for lumber.
