a 
3mm. broad at the dilated base, with pungent apex more or less reflexed. 
In habit these trees differ from A. Cunninghamii, 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. (Pls. 1, 3, figs. 1, 5.) 
In both the available cones an apparent orifice (ori., B) is visible on the 
swollen pulvinus of most of the bracts, behind the apex of the ovuliferous 
scale, possibly due to rupture of tissue. :
