This is described as a medium-sized tree 40 50 feet high with stout 

 spreading branches and branchlets, the latter clothed with dark green 

 leaves, 7 9 inches long, that are frequently in bundles of four ; the 

 cones are of ovoid shape, 4 5 inches long, the apophysis of the scales 

 with a transverse keel and depressed umbo. It is a native of the 

 mountains of Orizaba in central Mexico at a considerable elevation, 

 whence it was introduced by the Horticultural Society of London in 

 1839. The species, if separable from Pinus oocarpa, commemorates its 

 discoverer Theodor Hartweg, one of the most successful of the Society's 

 collectors and the introducer of several Mexican and California!! Conifers, 

 including Pinus patula, P. muricata, Cupressus Benthamii and 

 C. Goveniana. 



Pinus oocarpa.

A medium-sized tree, 40 50 feet in height, with a spreading head 

 and branchlets clothed with leaves in bundles of five, 8 10 inches 

 long, and egg-shaped, fawn-yellow cones (whence the specific name) 

 about 2 -5 inches long and 2 inches in diameter at the broadest ; the 

 scales very closely imbricated with a rhomboidal apophysis keeled 

 transversely and the central umbo depressed. It is said to be abundant 

 on the mountains of central Mexico especially on the volcano Jorallo 

 which is covered with it up to the limit of arborescent vegetation. Pinus 

 oocarpa was introduced by the Horticultural Society of London at the 

 same time as P. Hartwegii, but it had been previously discovered by 

 the German explorer Schiede. 



Pinus Torreyana.

A medium-sized tree 30 40 feet high with a trunk about a foot 

 in diameter and stout spreading branches; occasionally much larger. The 

 leaves, which are in bundles of five, are among the stoutest in the 

 genus, often a foot long and quite rigid; and the broadly ovoid cones 

 much resemble those of the European Stone Pine, Pinus pinea, in size, 

 shape and colour, but the scales of the exposed side have a much 

 more prominent apophysis tipped by a minute spine. Its habitat is 

 the most restricted of all the Xorth American Pines, being confined to 

 a small area in south California near the mouth of the Soledad river. 

 It was named by its discoverer Dr. C. C. Parry, in compliment to 

 Dr. John Torre y, " one of the wisest, most clear-sighted and industrious, 

 systematic botanists America has produced."
