Western Szech'uan: Mao-chou, woodlands and open country, 

 alt. 1600-2500 m., October 1910 (No. 4064). 



This new Spruce is characterized by its bright orange brown, glabrous shoots, 

 elongated buds with loosely imbricated reflexed bud-scales and by the bilobed nearly 

 rhombic-obovate cone-scales. It is most closely related to P. asperata Masters, 

 which grows in the same region and has pubescent, duller colored shoots, conical 

 winter-buds with much less loosely imbricated and scarcely reflexed bud-scales 

 and entire, rounded, obovate cone-scales. The bilobed cone-scales are very re- 

 markable and a constant character in the numerous specimens before us which 

 were collected from different trees. 



A picture of this tree will be found under No. 0336 in the collection of Wilson'a 

 photographs.
