In the note relating to this species above cited, I inadvertently 
stated that in P. densiflora the resin-canals are in the substance 
of the mesophyll; but this is only occasionally the case, the 
usual position is subepidermal. The cone-scale of P. Henryi is 
distinguishable by its deeply depressed umbo.
