Eucalyptus Dunnii n sp. is most ciosely aliied to E. Deanei Maiden^ 

 from which it differs in the exserted valves of the fruit and in the 

 timber^ which is white throughout from the sap to the heart. E. pro- 

 pinqua Deane and Maiden also resembles the new species in many 

 respects, but differs in the red timber and in the finer and more parallel 

 veins of the leaf. F. E. Fritsch.
