South Australia. 



Flinders Range, near Quorn (Max Koch). 



Road from Gladstone to Beetaloo, Flinders Range. " The tree (scarcely 

 more than a shrub) had the appearance of a "Whipstick Mallee" or " Peppermint " 

 (J. M. Black). 



Victoria. 



Lower Avoca Scrub, Wedderburn ; also Mildura (W. Percy Wilkinson) (both 

 labelled E.fruticetorum by Mueller). 



Wedderburn (J. Blackburne). This specimen is from trees used for oil- 

 distilling, and is certainly intermediate between E. fruticelorum and E. odorata ; 

 Inglewood (J. Blackburne). With broad juvenile leaves. Another form inter- 

 mediate between E. fruticetorum and E. odorata. 



" Mallee," Rushworth (A. W. Howitt, J. Blackburne) ; " Mallee," St. Arnaud 

 (A. W. Howitt). 



Nevf Soute Wales. 



" Blue Mallee." Locality for type of E. polyhvactea (R.T.Baker), West 

 Wyalong. " Willowy, light-coloured stems" (W.S.Campbell). "Mallee," Wyalong 

 (Forester J. G. Postlewaite, March, 1900). Bluish, glaucous cast, narrow leaves, 

 very similar to E fruticelorum,, but with hemisphei'ical fruits.

AFFINITIES. 



1. With E. calycogona, Turcz., var. celastroides, Maiden {E. celastroides, 

 Turcz.). 



Tlie only differences I can see between E. celastroides and E. fruticetorum 

 lie (a) in the shape of the fruits, which in the former appears to be always more or 

 less urceolate ; {b) we have the size of E. calycogona, var. celastroides, whicli attains 

 the dignity of a tree, while E. fruticetorum appears to be always of shrubby size. 

 At the same time we have many instances of species being of tree size in one district 

 and shrubby in distant localities. 



Coming to similarities, the oils are alike (the composition is, indeed, similar 

 to that of other oils not closely related). 



The anthers are identical, and in regard to other points the two plants are 

 similar, as far as I can see. One is not surprised to find some differences (assuming 

 they are the same) since E. calycogona, var. celastroides, is only recorded from West
