about 1.5 mm, thick, soft and flexible, slightly toothed, taper- pointed by a sharp 

 thickened tip, with 2 or 3 resin-diicts, one of which is frequently found in

 yellow. The pistil- 

 late flowers are lat- 

 eral, at some distance 

 away from the end 

 of the twig, slender- 

 stalked, subglobose, 

 6 mm. long, their 

 scales broad, ovate, 

 their bracts elhptic. 

 The cones, maturing

dish brown and somewhat shining, opening and shedding the seed soon after 

 ripening, and persist on the branches for two or three years; scales thin, shghtly 

 concave, rounded, only slightly thickened and scarcely ridged, the dull knob small 

 and terminated by a small usually deciduous prickle; they are dull purple on the 

 unexposed surfaces. The seed is nearly triangular, 4 mm. long, its sides rounded, 

 dark gray and slightly roughened and mottled; the wing is thin and delicate, 1.5 

 cm. long, 6 mm. wide, dark brown and shining, broadest about the middle; coty- 

 ledons 5 or 6. 



The wood is soft, weak, and brittle, very close-grained, light brown with few 

 and small resin bands; its specific gravity is about 0.39. It is not durable and 

 but little used, being seldom cut for lumber but to some extent for fuel. The 

 tree is also known as Cedar pine, Poor pine and Walter's pine.
