AFFINITIES. 



It naturally occurs to one to compare this species with other small fruited species, 

 e.g., Raveretiana F.v.M., Howittiana F.v.M. 



1. With E. Raveretiana F.v.M. 



Compare Plate 53, Part XII. E. Raveretiana is a large Box-tree ; E. brachyandra 



is described as a small tree with grey fissured bark; we do not know if they tend to 



approximate to each other in these respects, but the localities known for both are very 



few. 



The mature leaves of E. Raveretiana are narrow rather than broad, the fruits 



have the valves exsert, and the opercula are much more pointed. 



2. With E. Howittiana F.v.M. 



This is another small -fruited species; the fruit is, however, more spherical and 

 the leaves more lanceolate. It is also a very large tree, and I will again make 

 comparisons when E. Hoivittiana is figured. The anther-cells of E. Hoivittiana are 

 more parallel than those of E. brachyandra. 



3. With E. populifolia Hook. f. 



This species has sometimes the fruits so small, particularly in Queensland, that 

 the similarity may be noted. The leaves are usually shiny, while those of E. brachyandra 

 are dull. 



4. With E. melanophloia F.v.M. 



In shape of leaves, and in anthers, there is a certain amount of similarity between 

 E. brachyandra and some specimens of E. melanophloia from North- Western Australia. 

 But the fruits of the latter species are larger and usually, though not invariably, opposite 

 and sessile. 



5. With E. Brownii Maiden and Cambage, Proc. Roy. Soc N.S. IF. xlvii, 215 (1913), 

 which has sometimes fruits as small and of very nearly the same shape as those of 

 E. brachyandra, but the mature leaves of the former are long and narrow. 



6. With E. Spenceriana Maiden. 



But its true affinity lies, it appears to me, with those species with papery fruits, 

 which have thin rims and which have the tips of the valves well sunk. The group is 

 Angophoroid to some extent, and includes E. tesselaris F.v.M., E. papuana F.v.M., 

 E. clavigera A. Cunn., E. aspera F.v.M., E. Spenceriana Maiden, the latest described 

 member of the group, seems in some respects (leaves and inflorescence) nearest to 

 E. brachyandra, but the members of the group run into each other in a most intricate 

 manner.
