3 mm. broad at the dilated base, with pungent apex more or less reflexed. 

 In habit these trees differ from A. Cunningliamii, for, though fastigiate- 

 pyramidal in growth, the branching is not so defined or symmetrical, showing 

 little trace of the candelabra-like habit so familiar in the latter. There is 

 also a difference in the size and shape of the leaves, in their stomatal 

 markings, and in the much larger size of the ? cones. I must thank 

 Dr. Beccari for material of his species, which he most kindly sent me for 

 purposes of comparison ; also Dr. Stapf for carefully considering the points 

 of difference between the two plants. (Pis. 1, 3, figs. 1, 5.) 



In both the available cones an apparent orifice (ori., JB) is visible on the 

 swollen pulvinus of most of the bracts, behind the apex of the ovuliferous 

 scale, possibly due to rapture of tissue.
