282 PIITUS, OR 



The heart wood of old trees scarcely floats in water, and is a 

 most valuable timber. 



No. 48. PiNUS RADIATA, D. Don, the Radiated Cone Pine. 

 Syn. Pinus insignis macrocarpa, Hartweg. 



Leaves in threes, very slender, twisted, deep green, thickly 

 set on the branches, and from three and a half to four inches 

 in length. Sheaths short, smooth, a quarter of an inch long 

 on the young leaves, but very much shorter on the older ones, 

 and only partially persistent. Seed-leaves, on the young 

 plants, from seven to eight in number, rather long, and slender. 

 Branches compact, numerous, rather regular, and slender, par- 

 ticularly the lateral ones. Bark light brown, and rather 

 smooth. Buds smaU, numerous, imbricated, and full of resin- 

 ous matter. Cones mostly single, but sometimes two or three 

 together, rather conical, very hard, slightly incurved, pendulous, 

 and of a glossy light brown colour; six inches long, three 

 inches and a half broad near the base, which is uneven as well 

 as the sides, the outer side being much the longest. Scales 

 radiant, largest at the external base and down three parts of 

 the outer side of the cone, deeply divided, much elevated, and 

 prolonged into a blunt-pointed nipple, half an inch in length, 

 and three quarters of an inch broad ; those scales nearest the 

 base being bent backwards, the others more or leas convex, 

 widest at the base, bluntly conical, slightly angular, and termi- 

 nated by a blunt point ; the scales on the inner side of the cone, 

 and for four or five rows round the point, are very much smaller, 

 quadrangular, and slightly elevated, with their points quite 

 flat, or slightly depressed. Each cone contains from four- 

 teen to sixteen rows of scales, within each of which are two 

 small, nearly black seeds, with a very rough shell, and with 

 wings one inch long, and three-eighths of an inch broad. 



This beautiful pine resembles Pinus insignis in some respects, 

 but differs very much in foliage and cones ; the leaves of P. 

 insignis are much longer and stouter than those of P. radiata,
