by Hollick and Jeffrey to Protodammara. The parenchymatous 

 tissue of the cone-scales contains several thick-walled idioblasts 

 and the resin-canals and spaces form a conspicuous feature. A 

 series of vascular bundles runs radially through the scale, but no 

 evidence has been obtained of the occurrence of a double set of 

 vascular strands like those in Protodammara. The seeds — the 

 number of which, whether one or more, cannot be determined — 

 lie in a depression near the proximal end of the scales and there

is a ligule on the abaxial side of the seed or seeds (fig. 736, B, I). 

 The uppermost scales on the two cones shown in fig. 734, B and C, 

 illustrate the striking similarity to such detached scales as those 

 of Dammarites borealis : the raised patches, s, s, simulating seeds, 

 are formed by a crystalline substance filling cavities in the scales 

 and probably corresponding to the resin-ducts which form a charac- 

 teristic feature in the scales of Dammarites and Protodammara.
