AFFINITIES. 



1. With E. diehromophloia F.v.M. 



The original description says that E. latifolia in its characters rather resembles 

 E. diehromophloia, and they appear to be closest related. Both are Bloodwoods, but 

 E. diehromophloia has bark of a redder cast. Both have red timbers. 



The foliage of the two trees is usually very different, — that of E. latifolia being 

 broad, while that of E. diehromophloia is narrow. Compare Plate 168 with Plate 165 

 of Part XL. The buds and fruits are sufficiently approximate to require care. 



(Reference omitted from p. 319, Part XL) (E. diehromophloia and E. corymb osa). 



It has been already observed that the large-fruited forms of E. diehromophloia 

 display a good deal of similarity to E. corymbosa. The juvenile leaves enable us to 

 emphasise points of difference. If we turn to Plate 161, Part XXXIX (E. corymbosa) 

 we have juvenile leaves figured at 5, 6, la, and an intermediate leaf figured at lb. The 

 juvenile leaves of E. corymbosa are pedunculate, glabrous or with weak hairs ; those of 

 E. diehromophloia are sessile, stem-clasping, and scabrous. The intermediate leaves 

 are a good deal alike, those of E. corymbosa being longer in proportion to the width, but 

 the corresponding material of E. diehromophloia is not sufficiently abundant to speak 

 finally. 



The juvenile leaves of E. diehromophloia (Old Battery, Eidsvold, Q., Dr. T. L. 

 Bancroft, September, 1919) came too late to be figured on Plate 165. They are the 

 • first I have seen, to my knowledge. I cannot do better than say that I cannot distin- 

 guish them from some of the figures of E. setosa on Plate 158, Part XXXVIII. They 

 seem replicas of figs. 5 and 8, and almost as scabrous. The mature leaves of the two 

 species are, of course, very different, but the intermediate leaves of this specimen of 

 E. diehromophloia are very broad and lanceolate, as broad as those of the juvenile 

 leaves.

3. With E. corymbosa Sm. 



: * E. latifolia has very broad even roundish leaves, and belongs, on account of 

 its smooth bark, to the section Leiophloia?, unless this be subject to exceptions." 

 (•' Eucalyptographia," under E. corymbosa.) It is not correct to say that E. latifolia is a 

 member of the Leiophloia?, although there are Bloodwoods with barks more scaly. We 

 do not know the extent to which some of these tropical Bloodwoods vary in regard 

 to the roughness of their barks.
