 Western Szech'uan: north-east of Sungpan Ting, forests, alt. 

 2600-3800 m., abundant, August and October 1910 (No. 4060, type); 

 west and near Wen-ch'uan Hsien, forests, alt. 3000-3600 m., July 

 1908 and October 1910 (Nos. 2092, 4052); west of Kuan Hsien, Pan- 

 lan-shan, forests, alt. 3000-3600 m., abundant, October 1910 (Nos. 



4070, 4069, 4052 ^). 



This species is characterized by the short, broadly ovoid scales of its very resi- 

 nous winter-buds, its ferruginous, villose shoots, rather short, flat leaves, and by its 

 violet-purple, rather oblong, often densely resinous cones of medium size with 

 spatulate or cuneatenDblong bracts more or less exserted, the long acumen often 

 recurved. In transverse section the leaves are rounded at the margins and have 

 a single layer of hypoderm cells beneath the epidermis. In the type the resin- 

 ducts are nearly median, but they vary somewhat and in Nos. 2092 and 4052* 

 they are lateral and sub-epidermal. In the type specimen the cone is excessively 

 resinous and the exserted part of the bract is usually erect and of the same color 

 as the cone-scales. In No. 4070 the cone is only slightly resinous and the exserted 

 part of the bract is more or less recurved and pale brownish in colour. The various 

 specimens before us show intermediate conditions and there can be little doubt 

 that all belong to one species. 



This new Silver Fir is closely related to Abies Delavayi Franchet, which has 

 glabrous shoots, much larger, more barrel-shaped cones, and longer leaves revolute 

 at the margins; in cross-section these leaves are acute at the margins and have 

 lateral sub-epidermal resin-ducts.
