6.— ON EUCALYPTUS BICOLOR, A. Cunn.* 

 By J. H. Maiden. 



E. bicolor, A. Cunn., was first alluded to in a published work 

 in the following passage : — 



" E. hicoloi\ A. Cunn., MS., a species closely allied to E. 

 hcemastoma, Sm., but the marginal nerve is not so close to the 

 edge of the leaf (this is the ' Bastard Box ' of the carpenters) " 

 (Hooker in Mitchell's ' Journ. Trop. Australia,' 390, 1848). I 

 hardly think this can be taken, by itself, as an adequate descrip- 

 tion for purposes of priority. 



I have, however, examined the following specimens, and it 

 becomes a matter for consideration as to how far herbarium labels 

 shall be taken as evidence of publication. I have seen all the 

 specimens, and as regards those in Cunningham's handwriting, it 

 may be pointed out that he died in 1839 : — 



1. " Eucalyptus bicolor" in A. Cunningham's handwriting and 

 bearing the label "New Holland, A. Cunningham, Hooker, 1835." 

 This specimen was given b}^ Sir William Hooker to Bentham. 



2. '' E. bicolor, 1846. Sub-tropical New Holland, Lieut.-Col. 

 Sir T. L. Mitchell." 



The above are from Herb. Kew. 



A second specimen from Herb. Melb. of No. 2 labelled " No. 446 

 of Nov. 1846." 



There are two specimens on one sheet in Herb, Cant, ex herb. 

 Lindl, both from sub-tropical New Holland, Lieut. Col. Sir T. L. 

 Mitchell, and both labelled " E. bicolor, A. Cunn.," by Cunning- 

 ham himself. One label carries the additional information *'No.

 A. Cunn.)." These Proceedings, 1899, 621.
