on the tree in the Horticultural Society's Garden (see fig. 

 21 :><).), nearly I in. long, and fin. broad; convex on the sides, 

 imbricated, but not covered with resin. Leaves from 10 in. to 

 1 ft. in length; glaucous in every stage of their growth, flexuose; 

 and, when full-grown, partly bent downwards, as those shown in 

 fig. 2142. Sheaths above 1 in. in length, membranaceous, ash- 

 brown, shining, and nearly entire at the top,with numerous rings; 

 scales of the cones, in the specimens sent home by Douglas, 2 in. 

 long and \\ in. broad (see fig. 2140.). Seeds (a in fig. 2 140., and 

 b in fig. 2141) above 1 in. long,and nearly Ain.broad,much larger 

 than those of P. Coulteri shown at a in fig. 2141. ; wing very 

 short. Shoots of the current year covered with violet-coloured 

 bloom, like those of P. inops, but darker. Native of California. 

 Description. Douglas describes the leaves as in threes, very rarely in 



fours, from 11 in. to 14 in. long, sharp, round, and smooth on the outside, 



angular on the inside, serrated, more widely and conspicuously so towards 



the point, erect, but flaccid and drooping during winter ; sheath 1J in. long, 



liijht brown, chaffy, sometimes torn at the top. Stipules lanceolate and 



rigid. Male and female catkins erect. Flowers appearing in February and 



March. Cones 



of a bright green 



when young ; at 



the end of the 



first season, 



measuring from 



6 in. to 8 in. 



round, and being 



then of a more 



rounded form 



than they are 



when perfect, in 



the November 



of the following 



year ( see fig. 



2138.: when ma- 

 ture, ovate, re- 

 curved, pressing 



on the shoots 



for support, in 



clusters of from 



3 to 9, surround- 

 ing the stem ; 



remaining on the 



tree for a series of 



years ; and from 



9 in. to 1 1 in. long, and from 16 in. to 18 in. round ; some, however, are larger. 



Scalef spathlllate, 2\ in. long, having a very strong, sharp, incurved point 

 I in fig. 2140.) with abundance of pellucid resin. Seeds (see a mfig. 

 I.) somewhat oblong, tapering to the base; flattish on the inside, 1 in. 



Ion:/, and nearly |in. broad; shell thick, hard, brown ; wing yellow, short, 



htiff, and half the length of the seed, which it nearly encompasses; kernel 

 i,t to the taste. Cotyledons from 7 to 12. The tree does not attain 



quite ■-■<> large a size as the other gigantic species of the genus, which inhabit 

 ortbern and western parti of North America. The trees are of a tapering 



form, straight, and of regular growth; from 40 ft. to 120 ft. in height, with 



trunk-, from 2 ft. to 12 It. in circumference (or, as Douglas states in his letter 

 \V. .J. Hooker, from 1 10 ft. to I 10ft. in height, with trunks from 3 ft. 



to 12ft. in diameter), clothed with branches to the ground when standing far 

 01 .olitary. The largest and most, handsome trees inhabit the aqueous
