Australia and E. fruticetorum from Victoria arid New South Wales, and now traced, 

 for the first time to the eastern side of Spencer's Gulf, South Australia. 



I am not at present prepared to assert the identity of E. calycogona, var. 

 celastroides and E. fruticetorum, hut submit that my remarks at p. 80, Part III of 

 this work were quite justified, particularly when the material available at the time 

 the passage was penned is considered. 



Diels and Pritzel, speaking of E. celastroides, Turcz., say : — 



A very distinct species with small flowers and very short operculum. To the description may be 

 added : At length, a tree up to 20 metres (65 feet) high ; with a beautiful ashy-grey roughish bark, when 

 young smooth with ashy whiteness or reddish and shining ; the young leaves dull and glaucous, conspicuously 

 trinerved, broader than the shining mature leaf. — (Engler's Jahrb. 1904, p. 438.) 



The following two specimens from the Elder Exploring Expedition are in the 

 Adelaide Herbarium : — 



(1) "Camp 63, W.A., 27/7/91, R. Helms." 



This specimen was labelled by the late Professor Tate (who worked more or 

 less in conjunction with Mueller in the elucidation of the plants of this Expedition, 

 as " E. fcecunda and E. gracilis," apparently uncertain as to what name to attach to 

 it (Mr. Luehmann labelled it gracilis.) 



This is interesting in view of the early confusion of E. fruticetorum (after- 

 wards merged by him in E. gracilis) and E. fcecunda by Mueller. 



(2) "40 m. N.W. of Eraser Range, 5/11/91, P. Helms." 

 Called " Gungurru " by a native of Hampton Plains. 



2. With E. Thozetiana, E.v.M. 



The foliage of E. fruticetorum is more glaucous and broader than that of 

 E. Thozetiana, being shiny ; the juvenile foliage of the latter is much narrower (as 

 a rule) and if not so shiny as the mature foliage, certainly not glaucous, like that of 

 E '. fruticetorum usually is. The fruits of both species have a longitudinal rib ; those 

 of E. fruticetorum are more slender, and have a tendency to be urceolate. The 

 foliage of E. Thozetiana is rather pendulous, that of E. fruticetorum is inclined to 

 be rigid ; E. Thozetiana attains a much larger size, — up to 60 feet in Western 

 Queensland. 



3. With E. odorata, Behr and Schlecht. 



The " Whipstick Peppermint " (E. odorata) of the Mt. Lofty and Elinders 

 Ranges is no larger than E. fruticetorum of Flinders Range, and the anthers appear 

 similar, but the lid is as long as the calyx tube and the greyish calyx and whitish- 

 green leaves give it a different aspect (J. M. Black). 



E. fruticetorum lias an enlarged stigma ; so has E. odorata. I do not know 

 that this is a constant character in both species, but it is certainly very common in 

 both, particularly as the stamens fall away.
