This new Spruce is distinguished by its densely hairy shoots, relatively short, 

 very pungent leaves, and smooth, shining cones with broad, rounded scales. 

 The leaves subtending the winter-buds show a complete transition into bud- 

 scales and are remarkable in being distinctly hairy on the outer surface. This 

 new species is most closely related to P. asperata Masters, which differs chiefly 

 in its pale yellow-grey, often pruinose, much less hairy and often glabrescent 

 shoots, in its fawn-grey to chestnut-brown cones with less broad, usually rhombic 

 scales, and to a lesser degree in its bark which is greyish chestnut and peels off 

 in thin flakes. The scales of the winter-buds are also more loosely appressed and 

 often somewhat recurved at the apex of the bud.
