its shoots and foliage are very similar to the more downy states of the latter. 

 But in P. Armandii the leaves fall usually a year earlier, the shoots are more 

 slender, and the terminal buds have closer scales. 



P. BALFOURIANA, Jeffrey. FOX-TAIL PINE. 



(Gardeners' Chronicle, 1876, i., fig. 58.) 



A small tree, 20 to 40, rarely over 50 ft. high, forming in a small state a 

 very densely branched, bushy tree ; young shoots covered with minute but 

 scarcely visible down, so closely packed are the leaf-bundles. Leaves mostly 

 in fives, sometimes in fours, persisting as long as twelve or fifteen years, very 

 stiff and sharply pointed, about \\ ins. long, three-angled, two surfaces at first 

 white with stomata, becoming nearly green like the third with age ; margins 

 not toothed. The scales of the leaf-sheath curl back and make a sort of 

 rosette surrounding the base of the leaf cluster, and persist in that shape. 

 Cones 2-| to 5 ins. long, each scale armed with a minute, incurved prickle. 



Native of California ; introduced in 1852 by Jeffrey. Still an uncommon 

 pine, it is one of the most distinct and attractive for a limited area. It grows 

 very slowly, but its long retained, closely packed leaves give it a healthy, 

 vigorous aspect. It and its close ally P. aristata (see below) are quite distinct 

 in appearance, and differ from all other five-leaved pines in the rosette-like 

 arrangement of the leaf-sheath. 



P. ARISTATA, Engelmann (P. Balfouriana var. aristata, Engelmann\ is 

 very closely allied to the above, but is always distinguishable by conspicuous 

 exudations of whitish resin on the leaves, giving them very much the appearance 

 of being infested with some scale insect. The branches are more drooping, 

 the young shoots more distinctly downy, and the cones of P. aristata are 

 armed with considerably longer, slender prickles. Introduced in 1863 from 

 Colorado, where it grows on the outer range of the Rocky Mountains, also in 

 Nevada, Utah, and California. 



P. BANKSIANA, Lambert JACK PINE. 



(P. hudsonica, Parlatore ; P. divaricata, Dumont de Course!.") 



A tree varying in height from a scrubby bush to a tree 20 to 45 ft. high in 

 this country, but said sometimes to become 70 to 90 ft. high in N. America ; 

 young shoots without down ; terminal buds egg-shaped, in. long, encased 

 in resin. Leaves in pairs, persisting two to four years, i to if ins. long, flat 

 on one side, convex on the other, dark green, much curved ; leaf-sheaths 

 about in. long. Cones pointing forward, slender, conical, but very much 

 curved at the tapered point ; about l^jr ins. long, f in. wide at the base before 

 opening; yellow when ripe. 



Native of Eastern N. America, where it is the most northerly of pines, 

 and is spread over a vast region, usually in poor soil ; introduced early in 

 the eighteenth century. It appears to be very well adapted for poor sandy 

 soil, and has been planted in great numbers in Germany on that account. 

 It has not much to recommend it for gardens. Among pines with short leaves 

 in pairs and with resinous buds, this is to be distinguished by its slenderly 

 tapered cones, curiously curved like a bent little finger at the apex. 



P. BRUTIA, Tenore. CALABRIAN PINE. 



(P. pyrenaica, Carriere ; P. halepensis var. Brutia, Henry.) 



Although by some authorities regarded as nothing more than a form 

 of P. halepensis, this seems to me to be a distinct species. The tree itself
