Pinus 10 77 



in the eastern states are in Delaware Park, Buffalo, where there are eight trees 

 which, planted in 1871, were in 1897, 25 to 37 ft. high. A fine weeping variety, var. 

 pendula, Masters, which was imported from England in 185 1, and planted at 

 Woodenethe, Fishkill on Hudson, New York, is figured 1 in Garden and Forest, i. 

 392, fig. 62 (1888); and was, in 1882, 59 ft. high and 5 ft. 7 in. in girth. We have 

 not seen any tree showing this habit either in England or in its native country.

A tree, usually 20 to 30 ft. high and 1 ft. in diameter, occasionally attaining 

 100 ft. in height and 2\ ft. in diameter ; often divided about the middle into two 

 ascending stems. Bark \ to \ in. thick, brown, irregularly broken into large loose 

 scales. Young branchlets slender, glabrous, reddish brown, with prominent pulvini 

 separated by linear grooves. Buds cylindrical, pointed, brown, about an inch long, 

 with closely appressed scales. 



Leaves in threes, persistent three or four years, spreading, usually 4 to 5 in. 

 long, slender, firm and rigid, serrulate, ending in a sharp cartilaginous point, marked 

 by stomatic lines on the three surfaces ; resin-canals median ; basal sheath \ in. 

 long. 



Cones lateral, in one, two, or three whorls on the same year's shoot, in clusters 

 of two to four, deflexed, asymmetrical, oblique at the base, short-stalked, pale 

 brown, elongated-conical, 3 to 5 in. long ; scales thin, flat ; apophyses transversely 

 keeled, on the outer side of the cone, pyramidate, raised into conical knobs, and armed 

 with sharp spines, on the inner side flattened and with minute prickles. Seed oval, 

 black, grooved, \ in long ; wing about an inch long. 



The cones are developed at an early age, often appearing in whorls on the stem, 

 when it is only 2 or 3 ft. high ; and remain both on the stem and branches 

 unopened until the advent of a forest fire or the death of the tree. They are some- 

 times found embedded in the bark of old trunks. 



This species is found in arid sunny situations on the mountains of south-western 

 Oregon, south of the Mackenzie river, in ,the Siskiyou mountains, and southward 

 along the western slopes of the Cascades and the Sierra Nevada, and in the coast 

 range of California from Santa Cruz to the San Bernardino mountains, where it is 

 abundant at 4000 ft. It is most common in Oregon, usually growing in small groves 



1 This tree is also figured in Gard. Chron. x. 236, fig. 42 (1878).
