the lateral lobes of the scale were infolded so as partially to 

 conceal the ovule at the base and suggest the idea of a partially 

 closed carpel.

The proliferous cones of Pseudotsuga Douglasii are chiefly re- 

 markable for the fact that in passing into the leafy state the 

 bracts gradually lose the three-lobed apex which usually charac- 

 terizes them. 



In the herbarium of Linnaeus preserved in the rooms of the 

 Society is a specimen of the Common Spruce (Picea excelsa) m 

 which the fruit-scale within the bract, and seen from without, is 

 represented by a central axis with a lobe on each side. Looked 

 at from the inner side the two side-lobes are seen to be united at 

 the base by a transverse band and to form with the central lobe

 doubtful. The explanation seems to be that there is a central 

 axis bearing on each side a leaf or leafy process. These processes
