TlNUS IONDEEOSA. 167 



of the branchlets. The cones are larger than those of any other 

 Pine, being from 10 to 12 inches long, with a diameter of about 

 6 inches at the broadest part, and weighing from 4 to 5 lbs. ; the 

 scales are very thick, firmly adherent, of exceedingly hard ligneous 

 texture, armed with a strong hooked spine, smooth, polished, and of 

 a yellowish-brown colour. 



Habitat.— California, on the Santa Lucia, at 8,000 to 4,000 feet 

 elevation; also on the coast range as far as latitude 37° N. 



Introduced by David Douglas in 1832. 



Xotliing is known of the economic uses of this tree; the seeds are 

 large, and like those of the closely allied species Pinus Sabiniana, 

 edible. 



In England its growth is comparatively slow; although it has been 

 introduced nearly half a century, the oldest trees are, with rare excep- 

 tions, but of moderate dimensions, and present no special feature of 

 attraction; the foliage is tufted at the extremities of the shoots giving 

 the branches a very naked aspect; but, for the sake of its extra- 

 ordinary cones, P. macrocarjxi should be planted in every collection 

 where space can be found for it, and which should have a radius not 

 less than from 25 to 30 feet. 



The specific name macrocarpa- (fiatcpbo), "large," and (Kapmo), "fruit," 

 was appropriately selected by Dr. Lindley, on account of its remarkable 

 cones ; it is that by which this Pine is best known in this country ; 

 but the name Coulteri, given by Professor Don, hi compliment to the 

 discoverer, Dr. Coulter, is said to have priority of designation. 



Pinus ponderosa. — A large massive tree, varying in dimensions 

 according to situation ; on the slopes of the Californian mountains 

 attaining a height of from 150 to 200 feet, with a girth of 18 to 

 24 feet, but considerably less in the arid plains of Utah and in 

 the higher latitude of Oregon. The bark is a very noticeable and 

 distinctive character ; in the mature tree it is yellowish - brown, 

 and divided into large flat smooth plates, from 4 to 8 inches in 

 breadth. The branches are regularly whorled, at first growing 

 horizontally, but becoming decumbent by their own weight. The 

 leaves are confined to the extremities of the branchlets, radiating 

 in all directions, and varying in length from 6 to 12 inches, 

 rather rigid, three - angled, compressed, with roughish edges, and 

 deep glaucous green. The cones are ovoid, from 3 to 6 inches in 

 length, with the scales terminating in a short spine or umbo.
