This Spruce is fairly common on the higher ranges of northwestern Hupeh. 

 It forms a shapely pyramidal tree with short, dense horizontally spreading branches. 

 The shoots are very pale, quite glabrous and shining, becoming pale grey or almost 

 white the second year. The winter-buds are ovoid with poUshed dark brown 

 scales. The cones are very freely produced and remain on the tree for a year or 

 more after they are ripe. The specimens from Wutai-shan have slightly stouter 

 leaves than the type, but otherwise are identical. Judging from Mayr's remarks 

 it is probable that he had loose cones of P. Meyeri Rehder & Wilson as well as 

 shoots with cones attached of P. Wilsonii Masters when establishing his P. 

 Mastersii. 



Pictures of this tree will be found under No. 097 of the collection of Wilson's 

 photographs. 



Here may be added two Chinese species of this section, not collected during 

 the Arnold Arboretum expeditions.

This quadrangular-leaved Spruce is characterized by its hairy shoots, curved 

 non-pungent leaves, and medium-sized symmetrical cones with rounded or truncate 

 scales. It is most closely related to P. gemmata Rehder & Wilson, which has sim- 

 ilarly hairy shoots, more densely hairy buds, very pungent leaves and larger cones 

 with much broader scales. It is also related to P. asperata Masters, which has 

 paler, more yellow, less pubescent shoots, slightly pungent leaves, larger cones with
