. North American trees : being descriptions and illustrations of the trees growing independently of cultivation in North America, north of Mexico and the West Indies . Trees. 36 The Pines into broad, flat, irregular plates covered with thin, reddish bro^\Ti scales; the inner layers of the bark are yellowish brown. The twigs are stout, smooth, dark vellow at first, becoming much darker and roughened by the persistent bases of the bud-scales. Branch-buds are cylindric, gradually narrowed to the apex, about 4 cm. long, the lateral ones much smaller, the scales shining brown and fringed with long white hairs. The leaves are in sheathed clusters of 2 or 3, the 2-leaved clusters often occurring on young plants; they are dark green and shining, stout, 17 to 30 cm. long, closely small-toothed, tipped with a short thickened point, marked by many hnes of stomata on all faces, and contain 4 to 6 resin passages and 2 fibrovas- cular bundles; they are crowded at the ends of the twigs and per- sist for about two years. The flowers appear in Januar}- and Februar}- be- fore the new leaves ap- pear, the staminate ones cyhndric, to cm. long, usually incurved, with dark purple anthers. ' The pistillate flowers are nearly terminal, short- stalked, oval, 12 mm. Fig. Pine. joj^g^ jj^p ^^^^1^3 broadly ovate and pink, the bracts large. The cones are narrowly conic when closed, cylin- dric or conic-cyhndric when open, 9 to 14 cm. long, dark brown and shining, dis- charging the seed in October and persist until the following summer; their scales are thin, nearly flat, rounded at the apex, ridged and thickened into a low knob which is surmoimted by a small spine, the latter incun-ed on basal scales, recur\'ed on scales toward the apex of the cone; the unexposed portion of the scales is dark, duh purple beneath, dull red above. The seed is almost triangular, rounded on the sides, 5 to 7 mm. long, dark grav, mottled and roughened; the wing thin, fragile, dark brown and striped
