AFFINITIES. 



1. E. torquata, J. G. Luehmann {Vict. Nat., xiii, p. 14-7, 1897). 



Luehrnann says : — " It seems to have the greatest affinity to E. incrassata, 

 especially as regards the anthers." 



Mr. Luehmann, at the time of describing his species, had nOt seen the fruits. 

 A figure is given at Plate 13, and they may be described as follows : — About half an 

 inch long, with a width of half as much ; nearly cylindrical. The outside of the 

 fruit has corrugations, but tapering from half-way up the fruit the corrugations 

 gradually enlarge in size to the bass of the fruit, forming about nine wing-like 

 processes. These wings then sharply taper into the elongated pedicels forming 

 incipient wings on the pedicels, a very rare occurrence in any Eucalypt. The rim 

 of the fruit is well defined, sloping to the mouth, which is very slightly constricted. 

 The slender valves are free, but the tops appear never to rise flush with the mouth. 



Mr. L. C. "Webster, who states that he originally found E. torquata, has 

 furnished me with the following particulars in regards to its occurrence in the 

 Coolgardie district of Western Australia : — 



I have traced this eucalypt growing in a belt over 25 miles long by about a quarter of a mile 

 wide. The belt runs almost east and west (a few points south of east), and outside of this belt I have 

 only been able to discover a few isolated trees. 



The country through which they run is composed of diorite, with traces of ironstone occurring here 

 and there through the diorite. 



The trees for the most part follow the course of a ridge of low hills, and grow more plentiful 

 on these hills than where they cross the plains. The trees grow from 20 to 30 feet high ; the trunks 

 usually range from 4 to 10 feet from the ground to the branches ; the rough bark goes from the ground 

 to the branches, then the branches are smooth ; very free floweret' ; blooms first week in September to end 

 of December. [.See illustration, p. 120.] 



2. E. corrugata, Luehmann (Vict. Nat. xiii, p. 168, 1897). 

 Mr. Luehmann says : — ■ 



This species is evidently allied to E. incrassata, but none of the forms of that species have such 

 high ridges nor the same hemispheric shape of the calyx and operculum. 



It is evidently closely allied to the var. gouiantha of E. incrassata and to the 

 form with hemispheric operculum, figured at Plate 15, fig. 6a. I have not seen the 

 species. 



3. E. fcecunda, Schauer. 



E. incrassata shows close affinity to this species, but their relation will 

 recpiire a more detailed explanation than is convenient at this place. The matter 

 will be gone into at some length when E. fcecunda is dealt with. (See p. 117.)
