50 ON THE CLASSIFICATION OF EUCALYPTS, 



Mahogany f E. pilularis, " Blackbutt "; E. tereticornis, " Grey 

 Gum "j E. resinifera, first of all " Red Ironbark," but according 

 to the Flora Australiensis "Red Mahogany"; E. capiteUata, the 

 coast form of " Stringy-bark ;" and E. saligna, " Blue or Flooded 

 Gum." The specific name is not appropriate, as the leaves are 

 only exceptionally narrow and willow-like, being generally of the 

 size and form represented in Baron Mueller's Eucalyptograplma 

 (Vol. I., Dec. 2). 



(2) E. botryoides is known as "Bastard Mahogany"; E. hcemas- 

 toma, "White Gum"; E. piperita, "Peppermint"; F. obli qua, the 

 form of "Stringy-bark" common to Tasmania, Victoria, and the 

 southern part of N. S. Wales ; E. corymbosa, " Blood-wood "; and 

 E. paniculata, " White Ironbark." 



The plan of arranging the species according to the shape of the 

 operculum was followed by D'Candolle with certain modifications ; 

 and George Don, F.L.S., in enumerating the species in 1832, 

 gives descriptions of them in a similar manner. He remarks, on 

 the authority of R. Brown, that there were in New Holland (as 

 Australia was then called) about 100 species, but "hardly half of 

 tint number were rightly known." His list is as follows : — ■
