Abies 719 



all other species in the median leaves above, in that case, being directed 

 backwards and not forwards. Leaves short, up to f inch long, broad, 

 rounded at the entire or slightly bifid apex ; in most cases with four to six 

 broken lines of stomata on their upper surface near the tip ; resin-canals 

 marginal. Shoots brown, shining, glabrous. Buds large, ovoid, non- 

 resinous. 



VI. Leaves irregularly arranged; those on the lower side of the branches not truly 

 pectinate. 



24. Abies Pindrow, Spach. W. Himalayas. See p. 755. 



Leaves all directed more or less forwards ; those above irregularly and imper- 

 fectly covering the branchlet ; those below mostly pectinate, but with some 

 directed downwards and forwards. Leaves soft, pale green, up to z\ inches 

 long, bifid at the apex with two sharp cartilaginous points ; resin-canals 

 marginal. Shoots grey, glabrous. Buds large, globose, resinous. 



25. Abies concolor, Lindley and Gordon. Colorado, Utah, Arizona, New Mexico, 



Northern Mexico, Southern California. See p. 777. 

 Leaves imperfectly pectinate both above and below, some in the middle line 

 being always directed forwards and not laterally outwards ; up to 2 to 3 

 inches long ; apex entire ; upper surface convex and not grooved, bearing 

 fifteen to sixteen lines of stomata ; resin-canals marginal. Shoots smooth, 

 olive-green, glabrous. Bud large, conical, resinous. 



26. Abies lasiocarpa, Nuttall. Western N. America. See p. 800. 



Leaves either (A) in an imperfect pectinate arrangement, or (B) with most of 

 the leaves directed upwards, those in the middle line above crowded, and 

 standing edgeways ; \\ inches long, narrow, usually entire, with con- 

 spicuous lines of stomata on the upper surface, especially in its anterior 

 half. Resin-canals median. Shoots smooth, with a moderately dense, 

 short wavy pubescence. Buds small, conical, resinous. 



Four species, A. Delavayi, Franchet j 1 A. Fargesii, Franchet ; 2 A. squamata, 

 Masters ; 8 and A. recurvata, Masters ; 4 occur in the mountains of western China 

 and are not included in the above list. The two first species are reported by 

 Masters to have been introduced by Wilson ; but, on inquiry, we find that only one 

 species of Abies from China is now growing in the Coombe Wood nursery. It is 

 probably A. Fargesii; but, as the plants are still very young, we are uncertain of 

 this identification, and think it best to leave this species undescribed for the present.
