RANGE. 



This species is confined to Queensland, and the range is fully dealt with at 

 Part XLIII, p. 91. The following additional notes, which contrast E. maculata and 

 E. citriodora in Queensland are furnished by Dr. H. I. Jensen, the geologist. Eolh 

 species are Calciphobe. The letter m refers to maculata, and c to citriodora.

AFFINITY. 



With E. maculata Hook. 



I have gone into the question of maintaining E. citriodora as a variety of 

 E. maculata or not, in Part XLIIT, p. 88. to which I refer my readers. Let us turn to 

 Plate 178. The question of the desirability of separating them into species seems to 

 come under two heads — 



1. Morphologically, E. maculata appears to be coarser in its organs than 

 E. citriodora, or let me say that under the former species I have come across larger 

 leaves and fruits than I have seen in the latter. But this requires further collecting 

 to decide. 



2. The very much greater percentage of Citronellal in E. citriodora is obvious. 



Bentham in his Key (B.FL, hi, 199) separated the two species mainly on the 

 leaves : — 



Ovate-lanceolate, or lanceolate, with numerous fine, close 



almost transverse veins ... ... ... ... ... E. citriodora^. 



Narrow-lanceolate, rigid, with more oblique veins E. maculata. 



But we have a wider knowledge of the species than in Bentham's time. Mueller 

 and Bailey both combined the two species.
