EUCALYPTUS OLDFIELDII. 



nearly roundish form ; but still both these species are very different from the Renantherse, although 

 they offer an approach to the Micrantherse. 



The close affinity of E. Oldfieldii to E. Drummondi 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 

 flowerstalks 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. Drummondi should prove a mere variety, as seems likely, then the geographic 

 range of E. Oldfieldii wOl have to be recorded as much further southward, than we hitherto were 

 aware. 



This Eucalypt was named in honor of Mr. Augustus Oldfield, who as an emissary of the 

 Melbourne botanic department obtained this with numerous other then undescribed plants in 

 West-Australia, and who had previously distinguished himself by several collecting journeys in 

 Tasmania also, where he was the first discoverer of some of the rarest alpine plants.
