pistillate with violet, obovate scales, lateral, erect. Fruit: cones erect, 

 cylindrical to ovoid, their broad obtuse scales deciduous from the per- 

 sistent central axis. 



This small conifer has smooth bark divided by shallow 

 fissures somewhat roughened by cinnamon-red scales, and 

 drooping lower branches, the upper ones forming spire-like 

 heads. If you take hold of a branch it feels quite soft in 

 the hand. The needles which are rounded or shallow- 

 notched at the apex, are whitish below with a green midrib 

 and the two resin-ducts are imbedded in them. The buds 

 are small, round and gummy.
