EUCALYPTUS GUNNII, Hook. f. 



r i Cider Tree " or " Cider Gum."} 



BOTANY. 



Historical. This species was described by Sir J. D. 

 Hooker in 1844 in the " London Journal of Botany " (III. 

 499), and later in "Flora Tasmania" (I. 134. t. 27). 

 Bentham also records it in his " Flora Australiensis " 

 (1866, III., p. 246), whilst Mueller, in his " Eucalypto- 

 graphia " (1879, Dec. IV.), gives a very full description, 

 together with a plate. (See under " Remarks.") 



Deane and Maiden treat pretty fully of the species, its 

 allies and affinities, in the Proc. Linn. Soc. N.S.W. 1901, 

 and later Maiden devotes special attention to the species 

 in Proc. A.A.A.S. 1902, which practically covers the 

 ground of his paper on E. Gunnii, Hook, f., read before 

 the Linn. Soc. N.S.W. in the previous year. In this paper 

 a long list of synonyms is given, together with many pro- 

 posed new varieties. 



Remarks. The name E ' . Gunnii was bestowed by Sir J. 

 D. Hooker on what is known as the " Cider Tree " of Tas- 

 mania, as shown by his own writings, and repeated by Ben- 

 tham, Mueller, Rodway, and others; and this point should 

 be borne in mind when writing on the species. 



Now, this " Cider Gum " Eucalyptus, as far as we have 

 been able to trace, is only found in Tasmania and only 

 there in certain localities, on the central plateau as far as 

 we can ascertain but never on the mainland of Australia. 

 In fact one of us paid a special visit to the Kosciusko 

 Ranges and their branches to search for it, but so far with- 

 out success. Of course it may be there all the same, 

 although museum collectors, settlers, schoolmasters, and 

 others have all joined in the search, but have so far failed 

 to locate it. 



Whatever tree is now placed under the name it must be 

 a xtne qua non that it is identical with the " Cider Tree " 

 of Tasmania, for that was the original intention of Hooker. 

 His description accords with that particular tree, and 

 Bentham's reproduction in " Flora Australiensis " (III., 

 p. 246) equally so, for it accurately describes the material 

 in this museum obtained from the Tasmanian " Cider 

 Tree " by Mr. L. G. Irby, the museum collector, acting 

 under Mr. L. Rodway 's direction. 



Mr. Irby states in this connection: " This tree gets its 

 local name from a sweet exudation which flows from it at
