Evergreen aromatic trees with thin fibrous bark and 

 scattered flattened branches. Leaves scale-like adnate 

 and imbricate in 4 rows, oblong, with free acute tips, 

 somewhat dimorphous. Staminate cones of 12-16 sub- 

 peltate broadly ovate pointed scales, bearing usually 

 4 pollen-sacs. Pistillate cones composed of 4-6 small 

 coriaceous valvate scales, only the middle pair fertile ; 

 ovules 2. Mature cones oblong, scales oblong ; seeds 

 unequally 2-winged, maturing the first year. 



1. L. decurrens Torr. Mostly a rather small tree with bright 

 cinnamon-red bark and spreading branches; leaves pale green, 

 4-8 mm. long, the lateral ones without glands, nearly covering the 

 flattened, obscurely pitted inner ones; staminate cones oblong- 

 ovate, 5-6 mm. long; fruiting cones 2 cm. long and about 8 mm, 

 thick ; scales with short somewhat recurved mucro ; seeds ob-

 binate or ternate. Staminate cones oblong-ovate ; an- 

 ther-cells 4-8 under each shield-shaped scale. Pistillate 

 cone of 2 or 3 series of fleshy scales, with 2 erect ovules to
