770 MISCELLANEOUS NOTES ON EUCALYPTUS, I., 



pretty uniform diameter of say two inches, with an average height 

 of say eight feet. At the same time I have seen it three inches 

 in diameter, with a height of fifteen feet. Its trunk is smooth, 

 with ribbons, and its timber white. 



As to the nomenclature of Cunningham's plant, it has, as 

 already stated, been suggested that it is the E. pulveruhnta of 

 Sims' Bot. Mag. When I was in England I ascertained that an 

 absolutely authentic specimen of Sims' plant was not in existence, 

 and I see no reason for disturbing the generally accepted view 

 that the Argyle Apple is E. 'pulveridenta. 



A portion of Mr. Baker's argument (loc. cit. p. 346) is based on 

 inference connected with the difficulty of getting seed to England 

 in time for flowering in LSI 9 (date of Sims' plate). Mr. Deane 

 and I have already (these Proceedings, 1901, p. 550) dealt with 

 this objection. Nevertheless it may be shown that George Caley, 

 Sir Joseph Banks' seed and plant collector, was in E. pulverulenta 

 countr}^ at least as early as 1804. 



I feel very strongly that priority of a species may not be dis- 

 turbed on deductive evidence of that kind which does not 

 amount to absolute certainty. The destruction of the so-long 

 undisturbed application of the name E. pulvertdenia to the 

 Argyle Apple can only be permitted on the clearest evidence. 

 At the same time I think that the differences between E. 2nilvi- 

 gera, A. Cunn., and E. cordata, Labill., may be sufficient for us 

 to keep them apart for the present. I therefore, though with 

 diffidence, recommend that Allan Cunningham's name of E. pidvi- 

 gera be allowed to stand for the Cox's River and Cow Flat plant. 

 The species is undoubtedly very close to E. cordata, Labill. 

 Compared with that species it is a slenderer tree, has smaller 

 leaves, which are more coriaceous and which are entire (not 

 frequently crenulate as in E. cordata). The valves of E. cordata 

 are more sunk, those of E. pulvigera being exserted and the rim 

 being grooved (there is some grooving in a type-specimen of 

 Labillardiere). The shape of the fruit of E. pulvigera tends to 

 be urceolate, while that of E. cordata is more hemispherical.
