32 WILSON EXPEDITION TO CHINA 



This variety differs from the type in the shorter, stouter leaves, more elongate 

 and more purple cone-scales and in the somewhat darker more fulvous or pinkish 

 branchlets. In the texture and shape of the cone-scales it approaches somewhat 

 P. Balfouriana Rehder & Wilson, which has narrower scales, contracted above 

 the middle, wavy incised, and more purple in color; the leaves also are longer and 

 more slender. Picea montigena Masters, differs in its cinnamon colored cones with 

 very minutely erose or sometimes almost entire scales. 



This variety is a common tree round Tachien-lu and in general appearance 

 and habit resemble the type. Pictures of this tree will be found under Nos. 187 

 188, 191 of the collection of Wilson's photographs and also in his Vegetation of 

 Western China, Nos. 344, 345.

Western Szech'uan: west of Kuan Hsien, Pan-lan-shan, forests, 

 alt. 3600-4100 m., June 1908 (No. 2084, type) ; north-east of Tachien- 

 lu, Ta-p'ao-shan, forests, alt. 3000-3300 m., July 1908 (No. 2082). 



This new species is most closely related to P. likiangensis Pritzel, from which 

 it is distinguished by its densely villose shoots, much less prominent petioles, more 

 compressed, longer and pungent leaves, rather different cones and larger, lanceo- 

 late bracts. 



Picea hirtella is a rather rare tree with a relatively slender trunk, and short 

 thin branches forming a pyramidal head. The leaves are comparatively long and 

 the shining yellow-brown cones are particularly striking. In No. 2082 the cone- 

 Bcales are rather more attenuate at the summit than those of the type.
