III. LEAVES ON LATERAL BRANCHES NOT PECTINATE ABOVE, BUT DENSELY CBOWDED, THOSE IN THE 



MIDDLE LINE DIRECTED FORWARDS IN IMBRICATED BANKS, THEIR BASES NOT BEING APPKESSED 

 TO THE BRANCHLET. ON THE LOWER SIDE OF THE SHOOT THE LEAVES ABE IN TWO LATEBAL 

 BETS. 



Resin-canals marginal.* 



A. Nordmanniana, Spach 2 ; Caucasus. Leaves up to 1J inch long, with white lines of 

 stomata beneath, with rounded bifid apex. Shoots smooth, with short scattered 

 erect pubescence. Buds ovoid, brown, non-resinous. 



<& A. amabilis, Forbes; western N. America. Leaves in arrangement and size like 

 those of A . Nordmanniana, but much darker shining green and with a truncate 

 bifid apex, with white bands of stomata beneath ; they emit a fragant odour when 

 bruised. Shoots smooth, with short wavy pubescence. Buds small, globose, 

 resinous. 



A. religiosa, Schlechtendal ; Mexico, Guatemala. Leaves about 1 inch long, with 

 whitish lines of stomata beneath, gradually narrowing from the middle to the 

 usually entire apex which is occasionally slightly emarginate. Shoots with 

 prominent pulvini and dense minute erect pubescence. Buds shortly cylindrical, 

 resinous. The median upper leaves are much less numerous than in the two pre- 

 ceding species. 



A. Mariesii, Masters ; Japan, Formosa. Leaves shorter and broader than in A. 

 Veitchii, with white bands of stomata beneath, widest in their upper third, with a 

 rounded and bifid apex. Shoot densely covered with a ferruginous pubescence. 

 Buds small, globose, resinous. 



Resin-canal median. 



A. Veitchii, Lindley ; Japan. Leaves up to 1 inch long, truncate and bifid at the 

 apex, uniform in width, silvery white beneath. Shoots smooth, covered with dense 

 short erect pubescence. Buds small, globose, resinous. The upper median leaves 

 point forwards and stand off from the shoot at a wider angle than in A . Nordman- 

 niana. 



A. sachalinensis, Masters; Saghalien, Yezo, Kurile Isles. Leaves long and slender, 

 up to If inch, uniform in width, with a rounded and bifid apex, silvery-white 

 beneath. Shoots with prominent pulvini, and a dense, short pubescence confined to 

 the grooves. Buds small, globose, resinous. 



A. sibirica, Ledebour ; N.E. Eussia, Siberia, Turkestan. Leaves long and slender, 

 up to H inch, with narrow white bands of stomata beneath, uniform in width ; 

 apex rounded and either slightly bifid or entire. Shoots ashy grey, quite smooth, 

 with a scattered minute pubescence. Buds small, globose, resinous. 



IV. LEAVES ON LATEBAL BRANCHES NOT PECTINATE ABOVE ; THOSE IN THE MIDDLE LINE COVEBING 



THE BRANCHLET, AND CURVING UPWARDS AFTER BEING APPBESSED TO THE SHOOT FOB 

 SOME DISTANCE AT THEIR BASE. THE LEAVES ABE IN TWO LATEBAL SETS ON THE 

 LOWER SIDE OF THE BRANCHLET. KESIN-CANALS MABGINAL. 



A. nobilis, Lindley ; Washington, Oregon, California. Leaves above closely ap- 

 pressed by their bases to the branchlet which they completely conceal ; about 

 1 inch long, entire at the apex, flattened, grooved on the upper surface in the 

 middle line ; stomata usually present on both surfaces. Shoots with a dense, short, 

 brown pubesence. Terminal buds girt at the base by a ring of acute or subulately- 

 pointed pubescent scales. 



A. magnifica, Murray ; Oregon, California. Leaves above appressed at their bases 

 for a short distance only to the branchlet, which they do not completely conceal ; 

 longer than in A. nobilis, up to If inch, entire at the apex, quadrangular in section, 

 not grooved on the upper surface ; stomata always present on both surfaces. Shoots 

 and buds as in A . nobilis. 



1 A. nwmidica with strong shoots is distinguished from all these species by the leaves of the upper side 

 being directed backwards. 



a A. cilicica, with strong shoots, resembles a weak A. Nordmanniana.
