matter is not settled to the point of legal proof. I have expressed myself pretty strongly 

 at the bottom of page 97, Part IV, bnt there is a certain advantage in stating a case 

 both ways. 



In Part rV we have the case stated as E. incrassata var. dumosa; in this Part as 

 E. dumosa. At the present moment the evidence seems to point to the view that E. 

 dumosa cannot be usefully separated from the typical conoid-operculumed E. incrassata, 

 while E. incrassata var. angulosa has even more claims to be considered a distinct species 

 than E. dumosa has. 



The revisionary statement of the case in this Part will, I confidently expect, 

 cause Western Australian botanists and collectors to endeavour to ascertain all that 

 there is to be known about Western Australian forms, and other botanists to contribute 

 useful information which has become available since the publication of Part IV (fifteen 

 years ago). 



2. With E. oleosa F.v.M. 



It is occasionally very difficult to discriminate between the two species on 

 herbarium material, unless anthers be available, when it will be seen (compare Plate G6, 

 Part XV) that the two species are very different. The operculum of E. oleosa is as a 

 rule elongated, the calyx-tubes more ovoid, and the tips of the valves more attenuate. 

 The colour of the timber is reddish, that of E. dumosa being brown. E. oleosa as a rule 

 goes by the name " Red Mallee," and E. dumosa " White Malice."
