The flowers appear in June, the staminate in short, crowded clusters, oval, 12 mm. long, with darii orange- red anthers. The pistillate flowers are scaly-stalked, nearly terminal, sohtary or in pairs, oblong-oval, 8 mm. long, their scales broadly ovate, dark purple and with long, slender tips. The cones are horizontal or somewhat pendent, ovoid, 6 to 10 cm. long, 4 cm. thick, dark purpHsh brown, nearly sessile, opening and dropping their seed in September and October; their scales are thin, their tips somewhat 4-sided, but slightly thickened and ridged, the central elevated knob terminated by a slender upcurved prickle often 18 mm. long, light reddish brown and very brittle; the unexposed portion is dull red. The seed is nearly oval, 6 mm. long, flattened, light brown and mottled with black; wing light brown, oblong, obUque, about 8 mm. long and varying considerably in width; cotyledons 6 or 7. The wood is soft, weak, close-grained, and reddish; its specific gravity is about It is sometimes used for mine timbers and for fuel. 14.
