cells and a lower one of bast-cells. In Piceas (Spruces) the bast- 

 cells and the ducts are on the same side; and the stomata in the 

 flat-leaved Spruces (e. g. P. ajanensis) mostly on the opposite 

 side." This is in accordance with the observations of Bertrand 

 and MacNab ; and I can myself abundantly confirm it even in the 

 case of the species which has given rise to these remarks.

This species closely resembles P. Alcockiana or P. obovata, but 

 may be distinguished from the former by the hairy branches, the 

 less prominent pulvini, the thinner cone-scales, persistent bracts, 

 and wider wing to the seed. From P. obovata it differs in the 

 pulvini and in the shorter broader wing to the seed (Schmidt). 

 ine buds have a curious appearance of being embedded within 

 the apex of the branches, owing to the abrupt passage from the 

 thick and crowded pulvini to the thinner bud-scales. The cones 

 are cylindric generally about 2 inches long, but sometimes 

 scarce^ ! mch ^he leaf-structure is the same as that of 

 ■r. Alcockiana and P. obovata. 



Traces referred to this genus have been found in the Miocene 

 and Cretaceous deposits.
