II. Leaves on the lateral branches pectinate in arrangement ; the two lateral sets 

 either in one plane, or with their upper ranks directed upwards as well 

 as outwards, showing a V-shaped depression, as seen from above, between the 

 two sets. 



* Resin-canals marginal} 



3. Abies bracteata, Nuttall. California. See p. 796. 



Leaves long, 2 inches or more, rigid, ending in a spine-like point. Shoots

 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, \\ to i\ inches long, bifid at the apex ;

6. Abies firma, Siebold and Zuccarini. Japan. See p. 762. 



Leaves in a V-shaped arrangement, rigid, very coriaceous, broad, up to \\ 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 A. 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.

 scattered short erect grey pubescence. Buds globose, resinous. 



1 1. Abies Fraseri, Poiret. Alleghany Mountains. See p. 806.

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.
