PINUS 181 



from time to time been raised at Kew, but are spring tender and grow slowly. 

 Except in the south-western gardens it has little interest to cultivators. 

 In the Himalaya it is a tree 80 ft. high ; its shoots are smooth, and its leaves 

 three in a bundle. The leaves of the Cambridge tree are 2 to 4 ins. long, 

 dark dullish green, sharply pointed ; leaf-sheath i in. long, the scales 

 becoming loose by winter and falling away the second year. In branch 

 and leaf it is like P. Bungeana, and has a similar peeling bark ; the trunk, 

 however, does not become white in old trees like that of Bungeana, w r hich 

 differs also in its brighter leaves and quickly deciduous leaf-sheath. The 

 cones of P. Gerardiana are described by Brandis as 6 to 9 ins. long, 4 

 to 5 ins. wide- -thus many times larger than those of P. Bungeana. 



P. HALEPENSIS, Miller. ALEPPO PINE, 



A tree rarely more than 30 to 50 ft. high in this country, but 70 to 80 ft. 

 in favourable conditions ; here it usually forms a rounded head of branches, 

 but is more pyramidal in the south of Europe ; young shoots pale grey, 

 smooth ; buds slenderly conical, pointed, non-resinous, about \ in. long, 

 with the points of the scales slender, fringed, and recurved. Leaves in 

 pairs (rarely in threes), falling the second and third years ; i\ to 4^ ins. 

 long, very slender ; leaf-sheath to i in. long. Cones pointing "backwards, 

 2^r to 3^- ins. long, I to \\ ins. wide at the base, tapering to a slender point ; 

 scales unarmed ; stalk i to | in. long ; they are produced in whorls and 

 remain several years on the branches. 



Native of S. Europe as far west as Spain and east to Asia Minor ; 

 introduced in the seventeenth century. Although tender in a young state 

 it is hardy enough when once established ; several examples at Kew have 

 withstood 31 of frost, and are quite healthy. This species and P. Brutia 

 are distinguished among two-leaved pines by the non-resinous buds having 

 recurved scales. The newly cut or bruised young wood has a most pleasant 

 aromatic odour. It is the commonest pine along the south coast of Europe, 

 and reaches perhaps its finest development along the Dalmatian coast, 

 where I have seen it 70 to 80 ft. high, remarkably handsome in its heavy 

 plumose masses of foliage. It_ covers bleak rocky promontories near 

 Ragusa. (See P. Brutia for differences between it and the present 

 species.) 



P. HARTWEGI, Lindley. HARTWEG'S PINE. 



(P. Montezumse var. Hartwegi, Engelmann.} 



A very near relative of Montezuma's pine, but found in Mexico at higher 

 levels and under colder conditions. It is, in consequence, a much hardier 

 tree. There is a good specimen, perhaps 30 ft. high, in Windsor Forest, 

 which is the nearest to London that I know of, of any size. I have had 

 it also in cone from Luscombe Castle, Dawlish, and it is at Bayfordbury 

 and Westonbirt. Leaves mostly in fives, but also in fours ; 5 to 6^ ins. 

 long, crowded at the end of the shoot ; stiff, grey-green, closely" and 

 minutely toothe.d on the margin, sharply pointed ; leaf-sheaths quite 

 persistent, f to I in. long. Cones 3 or 4 ins. long, i^ ins. wide ; scales 

 with a decurved spine-tipped boss. It differs chiefly from P. Montezumae 

 in its shorter leaves and much hardier constitution. It is a tree up to 70 ft. 

 high, with stout young shoots. 



Discovered and introduced by Hartweg in 1839.
