Notes on some South Australian Eucalypts 

 By J. H. Maiden, I.S.O., F.R S , Honorary Fellow. 



[Read August 9, 1917.] 



The following are a few additional notes on South Aus- 

 tralian eucalypts, chiefly concerned with the nomenclature of 

 the subject, and in the course of the paper I have had occasion 

 to refer to a recently-published article by Messrs. R. T. Baker 

 and H. G. Smith/ 1 ) in which some of my previous determina- 

 tions have been called in question. 



1. E. diversifolia, Bonpl. (E. santali folia, F. v. M.). 



The writers who have dealt with this species are : — 



1. Bonpland, who first described it under the name of 

 E. diversifolia in 1813,< 2 ) and his descriptive account is 

 reproduced in my "Critical Revision of the genus Eucalyptus" 

 (hereinafter called Grit. Rev.), part vii., p. 197. 



2. Mueller, who in 1855 redescribed the species under 

 the name of E. santalifolia (see Crit. Rev., vii., p. 199). In 

 his "Eucalyptographia" he figures E. jmchyloma, Benth., as 

 his E. santali folia, and makes a number of consequential 

 errors in the text. 



"E. santali folia, and E. packyloma, though placed widely 

 apart and into different sections of his anthereal system by 

 Bentham are, as far as I can judge, quite identical." — 

 Mueller, in "Eucalyptographia." 



We have Bentham's authority for the statement (B. FL, 

 iii., 206) that "this (E. santalifolia) is now reduced by F. 

 Mueller to a form of E. obliqua, but besides the foliage, the 

 shape of the fruit is different, being nearly that of E. 

 macrorrliyncha or E. caipitellata." 



This is additional evidence that Mueller did not really 

 know his own species, and, indeed, it is a very great advan- 

 tage to a botanist to see the species in the field. To visit 

 critical forms in the field has been an important object of 

 my life. Mueller once told me of some confusion which 

 Alphonse De Candolle caused in regard to one of his own 

 species, and, realizing the humour of the position, he added, 

 "He did not know his own child!" 



3. Bentham (B. FL, iii., 240) added E. diversifolia as 

 a synonym of E. viminalis, Labill., under which he 



(i) Trans, and Proc. Roy. Soc. S. Austr., vol. xl., p. 464. 

 (2) This work bears the date 1813 on the title-page, but the 

 latter parts were not published till 1816 (B. Fl., iii., 119).
