RANGE. 



It is confined to Western and South Australia. Mueller (" Eucalyptographia ") 

 gives its range as from Champion Bay to the Murchison River in Western Australia, but 

 the localities about to be quoted show that it extends to the Eastern gold-fields and to the 

 South Australian border. 



For a number of Western Australian localities, see Part XVII, p. 223, of the 

 present work. It is a species often obviously passed over as " Mallee," and we require 

 additional localities in order to properly map out its distribution. 



Western Australia (Additional Localities). 



About 4 miles north of Menzies (C. E. Lane Poole, No. 282). 



Bruce Rock to Merriden (Dr. F. Stoward, Nos. 16, 36). "Mallee," Tammin 

 (C. H. Ostenfeld, No. 512). Comet Vale (J. T. Jutson, Nos. 242, 250). 



South Australia. 



" Camp 10, S.A., Elder Exploring Expedition. 27th June, 1891. 15 feet 

 high." (R. Helms.) On the official map it is stated that some Mallee was found in 

 the vicinity of this camp, which is in South Australia, in, say, 27° 60' S. lat. and 

 131° long. E. 



AFFINITIES. 



1. With E. Drummondii F.v.M. 



" The close affinity of E. Oldfieldii to E. Drummondii remains to be noted. So far as I can judge 

 from Drummond's specimen No. 86, no other discrepancies of the latter exist than the smaller size of the 

 leaves, flowers and young fruits, and the comparatively greater length of the flower-stalks and stalklets ; 

 but such differences are not in every other case of specific value, and as the bud and ripe fruit remained 

 hitherto unknown, the final settling of this question is not yet possible. If E. Drummondii should prove 

 a mere variety, as seems likely . . . ." (" Eucalyptographia," under E. Oldfieldii.) 



E. Oldfieldii differs from E. Drummondii in the sessile inflorescence which is 

 arranged in triads (or when pedicellate), the pedicels are very stout and shorter than 

 those of E. Drummondii) and in different shaped buds and fruits, as will be seen by 

 comparing Plate 73 (fig. 11) and Plate 74 (figs. 1 and 2) for E. Oldfieldii with Plate 74 

 (figs. 3, 5, 6, 7, 9, 10) for E, Drummondii. The former is a Mallee, and the latter a 

 small tree. 



2. With E. Ewartiana Maiden, in Proc. Roy. Soc. N.S.W. liii, p. HI (1919). 

 This will be dealt with when E. Ewartiana is reached. 



Additional affinities have been dealt with in Part XVII, p. 225.
