AND THEIK ESSf:NTIAL OILS. 141 



This brings the record uj) to 21, and of these no less 

 than 12 are endemic, which is a large percentage of the 

 whole number, and i)rohablv due 1o tlie cjreat lencfth or 

 period ot isolation of Tasmania from the mainland. No 

 doubt other endemic species exist, but remain as yet unre- 

 corded, as much country is not yet o})eiied up. 



Rodway, in his " Flora of Tasmania," estimates 17 

 species, most of which stand, with the following additions 

 and alterations. In his list we replace-— 

 J'J . Sieheriana with K. viryata, 

 A\ haemastoma with K. /Jelegattnsls, 

 h\ pauciffora with A\ pliltbopfii/lla, 



while the following are added as new species: — 



E . Rodwayl, 

 K. taeiiiola, 

 I'J . nnudatd. 

 E. Inndns, Dehn., is superseded b\' A', liittaris, A. Cunn. 

 Records new for Tasmania are — 



I'J. Dtltyattnais, 

 A'. I'crriniana, 

 and we determine two species, which had hitherto been 

 regarded as common to both the mainland and Tasmania, 

 as now distinct, viz. — 



E . (imyyddlnia from E . (ini i/ydnUnd on the mainland, 



and — 

 E. actrvula from E. pa/iidosu. 

 It will no doubt come as a surprise to Eucalyptologists 

 to know that the Tasmanian A'. arnyydaliiKi is not indenti- 

 cal with the species on the mainland which has for so long 

 passed under that name : but the error has probably been 

 caused through various reasons. One, no doubt, has been 

 the want of access to Labillardier's original specimens, or 

 at least his plate, of the species, or a wider method of 

 classification, such as this investigation covers. However, 

 we have refrained from introducing a new name into the 

 already long nomenclature, and suggest a compromise as 

 stated under E. utnyydtdina. 



A', raduda of Hooker's " Flora Tasinaniae ' we have not 

 been able to place with the mainland tree of that 

 name, and are disposed to regard the remarks {Joe. cit.) as 

 referring partly to material of A', di/i '/f/dfdifia , A', linearis, 

 or even A\ lilsdont. 



E . Gunnii we consider as endemic to Tasmania, as up to 

 the present there appears no true evidence of this 

 " Cider Gum " tree occurring on the mainland.
