PINE FAMILY. S13 



A. Menzi6sii, Menzies' Spruce, of the Rocky Mountains and W., is 

 planted and likely to become common : fine tree, with broader and stiffer leaves 

 than the foregoing, almost prickly-pointed, silvery-whitish beneath; cones about 

 3' long, cylindrical, soft ; their scales rhombic-ovate, thin and pale. 



§2. Hemlock-Sprdce (Tscga). Cones hanging on declined branches of the 

 preceding year, smaltj persistenty and their scales persistent: sterile catkins 

 very smalt and globular ^ of a few anthers which open across; leaves flat, on 

 distinct little petioles, most of them spreading right and left so as to appear 

 2-ranked on the branch. ' ■ ■ , , ; > 



A. Canadensis, Hemlock-Spruce. Common on hills N., and planted 

 for ornament : large tree, with coarse wood, light and spreading spray, broadish- 

 liuear and blunt leaves only J' long, green above and white beneath, and. oval 

 cones only J' or f ' long, their bracts very short and hidden. 



A. Dougl^ii, Douglas Spruce, one of the tall trees from Rocky 

 Mountains and W. to the P/icific, planted but proves not quite hardy enough N., 

 is of this section : it has slender leaves 1' or more long, light green, indistinctly 

 2-rankcd; cones 2' -3' long, looae, with pointed and toothed bracts projecting 

 beyond the scales. 



§ 3. Fir. Cones set rigidly erect on the upper side of spreading branches of tlie 

 preening year, their scales and commonly conspicuous bracts falling away 

 with the seeds when ripe from the persistent slender axis : seeds resinous : 

 hntliers irregularly bursting : leaves flat, white beneath each side of the 

 prominent midrib, those on horizontal branches inclined to spread right and 

 left so as to appear 2-ranked. ' ' ■ __ - < 



» Balsam Firs, native trees: bark yielding Canada balsam from blisters, ^■c. 

 A.I bals^mea, Common B. Small tree of cold or wet grouncls N:,_hand- 

 somo when young, but short-lived, with worthless wood, narrow linear leaves 

 §' or less than I'long and much crowded, cylindrical violet-colored cones 2' -4' 

 long and 1' thick, their bracts wjth only the abrupt slender'point projecting. 

 A. Friserij Fraseb's or Southern B. Along the higher AUeghanies : 

 small tree, like the precedmg ; but the small cones (only l'^2' long) oblong- 

 ovate, with the short-pointed upper part of the bracts conspicuously projecting 

 and reflexed. 



* » Silver-Firs, &c., very choice ornamental trees, only the first at all common.- 

 ■1- Leaves blunt. ' 



A. pectin&ta, EuejOpean Su,ter-F. Large tree with wood, its horizon- 

 tal branches witli narrow leaves (greener above than in Balsam F., nearly as 

 white beneath and 1^' long) forming a flat spray; cones 6'-8' long, with 

 slender projecting points to the bracts. 



A. Nordmannitoa, from the Crimea and N. Asia ;. with thicker-set and 

 broader leaves than the foregoing, linear, curved, 1' long, deep green above and 

 whitened beneath ; cones large and ovate. 



A. Fichta, Siberian Silver-F. ; with thickerTset leaves than those of 

 European Silver-Fir, dark green above' and less white beneath ; cones only 3' 

 long, their short bracts concealed under the scales. 



A. gr&ndis, Great Siltee-Fir of Oregon and California : resembles a 

 fine Balsam Fir on a lai-ge scale, with broader leaves notched at the end, about 

 1' long, and thicker cones with concealed bracts. 



■<- Leaves acute or pointed, especially on main shoots, rigid, widely and abovt 

 equally spreading on all sides. 



A. Ceplial6nica, Cephalonian Silver-Fir: remarkable for its very 

 stiff almost prickly-pointed squarrosc leaves dark green above, white beneath. 



A. Finsapo, Spanish SiLVBKrFiR : resembles the last, but not so hardy, 

 leaves less pointed, and the bracts of the cones are concealed. 



3. IiARIX, liARCH. (The ancient name.) Trees planted for, ornament 

 and valuable for timber : branches slender, the young ones pendulonif : flov/- 

 ers in earliest spring, much before the leaves appear : catkins from latcr.*i
