Specific Character. —A. foliis curtis curvatis lenticularibus utrinque ftomatibus inftrudfis, ftrobilis 
cylindrico-ellipticis, conicis, fquamis parum concavis inequalibus vix fmuatis, bradteolis tenuibus minutis, 
feminibus alatis. 
Habitat in California, circa lat. 21° bor.; montibus, altitudine 5000-6000 ped. 
Foliage somewhat fafciculated. Leaves flightly curved, with a rib in the middle, and fometimes 
depreffed above, fo as to give the leaf a triangular or boat-fhaped form; from one-half to three-fourths of 
an inch long, rich graffy-green above, pale green beneath, very flightly filvery beneath, except when young 
and frefh; clofely but irregularly fet along the young branches, chiefly on the upper fide of the branch, 
except at the extremity of the {hoot, where they furround the whole twig; the margins of the leaf fmooth. 
Stomata on both Tides of the leaf, in four rows, with occafional interruptions and variations. The general 
appearance of the foliage is crowded. Phyllulae fubtriangular, with the angles 
rounded [fig. 1]; pulvini long and linear [fig. 2], breaking up into elongate | 3 J 
irregular triangular spaces as the twig becomes older and the bark breaks Fig. 1. 
[fig- 3]- The male flowers or catkins are very fmall [fee fig. 17], two- 
eighths of an inch long, and of a violet purple colour. Cones [fig. 16] ovoido- 
cylindrical, from one and a half to two inches long and half an inch in diameter; . 
according to Dr Newberry and Mr William Lobb, pendent and dark purple 
before they are mature, and, when ripe, pale fawn-coloured. Scales [figs. 6 
and 7] concave or faucer-fhaped, dull and opaque, more efpecially where they 
have been covered by the other feales; flightly thickened towards the expofed 
edge, not crenulated, but gently impreffed with two or three faint raifed lines: thefe lines are irregular and 
evanefeent, generally running ftraight down the expofed part of the fcale, or only Hoping flightly towards 
the centre. Sides of the fcale cut out unequally on the oppofite Tides, and ending with a tooth curving 
inwards at each fide of the ftipule. A fmall bradt, nearly two lines long, is fituated at the bottom of each 
fcale, faftened firmly to the back, and adpreffed upon the fcale. There is a yellowifh tooth in the middle, 
which is a mere prolongation of the rib or attachment to the fcale, and which is fo firmly fixed that the fcale 
may be torn off, leaving the greater part" of the rib flicking like a thread to the fcale. The top of this 
fcale, on each fide, is purple. At about one-third of its length from the top the breadth of the brabl is 
fuddenly contracted, and from thence Hopes gradually to its bafe. [See fig. 9.] 
The cones have conflderable refemblance to thofe of A. alba. They are of the fame colour, and the 
feales in both are fomewhat faucer-fhaped, and have their edges fmooth; but A. Hookeriana has the cone,
