II. Leaves on the lateral branches pectinate in arrangement, the two lateral sets either in one plane, or with their upper vanks directed upwards as well as outwards, showing a V-shaped depression, as seen from above, between the two sets.

* Resin-canals marginal.1

3. Abies bracteata, Nuttall. California. See p. 796.
Leaves long, 2 inches or more, rigid, ending in a spine-like point. Shoots glabrous. Buds peculiar in the genus, elongated, fusiform, membranous, non-resinous.
4. Abies grandis, Lindley. Western N. America. See p. 773.
Leaves all in one plane, those in the upper rank about half the length of those below, up to 2 inches long, bifid at the apex; upper surface grooved and without stomata. Shoots minutely pubescent. Buds small, resinous.
5. Abies Lowiana, Murray. California. See p. 779.
Leaves in a V-shaped arrangement, 14 to 24 inches long, bifid at the apex; upper surface grooved and with eight lines of stomata. Shoots and buds as in A. grandis.
6. Abies firma, Siebold and Zuccarini. Japan. See p. 762.
Leaves in a V-shaped arrangement, rigid, very coriaceous, broad, up to 14 inch long, ending in two sharp cartilaginous points. Shoots pubescent in the furrows between the slightly raised pulvini. Buds small, ovoid, only slightly resinous.
7. Abies homolepis, Siebold and Zuccarini. Japan. See p. 764.
Leaves in arrangement and appearance like 4. firma; but shorter, less coriaceous, narrower, and whiter beneath. Shoots with prominent pulvini, glabrous. Buds ovoid, resinous, larger than in A. firma.
8. Abies pectinata, De Candolle. Europe. See p. 720.
Leaves pectinate in one plane or tending to a V-shaped arrangement, about an inch long, slightly bifid at the apex. Shoot grey, with short pubescence. Buds ovoid, non-resinous.
9. Abies Webbiana, Lindley. Himalayas. See p. 750.
Leaves V-shaped in arrangement, up to 24 inches long, bifid, silvery white beneath. Shoots with prominent pulvini and deep grooves, with a reddish pubescence confined to the grooves. Buds large, globose, resinous.

10. Abies balsamea, Miller. Eastern N. America. See p. 803.
Leaves slender, scarcely 1 inch long, bifid at the apex, with six to eight lines of stomata in each band on the lower surface. Shoots, smooth, grey, with scattered short erect grey pubescence. Buds globose, resinous.
11. Abies Fraseri, Poiret. Alleghany Mountains. See p. 806.
Leaves as in A. balsamea, but shorter and whiter beneath, with eight to twelve lines of stomata in each band beneath. Shoots smooth, yellowish, with dense reddish curved or twisted pubescence. Buds globose, resinous.


1 A. cilicica and A. numidica, with weak shoots, come in this section. See Nos. 22 and 23.

2 Abies lasiocarpa, Nuttall, often has the leaves more or less pectinate, and might be sought for here. See No. 26.
