56 ON THE CLASSIFICATION OF EUCALYPTS, 



E. perfoliate*,, R.Br. ; Northern Australia. 



JE. Baxteri, R.Br, j probably from Kangaroo Island, and now 

 regarded as a variety of E. santalifolia, F.v.M. 



E. hypericifolia, R.Br.; from Risdon Cove, Tasmania, and now 

 joined with E. amygdalina, Labill. 



E. JRisdoni, Hook. ; collected by Brown at Risdon Cove. 



E. clavigera, A. Cunn. ; collected by Brown at Careening Cove, 

 Northern Australia. 



Caley, who resided in Parramatta from 1800 to 1810, when 

 only a small portion of the colony was known, could not have 

 noticed any of the Eucalypts excepting in those parts now 

 distinguished as the County of Cumberland and Hunter's River, 

 so his name does not appear to be connected with the genus. 

 Caley's time was not exclusively devoted to botany, for he made 

 valuable collections in every department of natural history. It 

 appears that he was the first to send to Europe specimens of the 

 " Red-flowering Ironbark," and the large variety of the " Swamp 

 Mahogany." He also collected specimens of the following 

 species : — 



E. polyanthema, Schau E. viminalis, Labill. 



E. bicolor, A. Cunn. E. metadata, Hook. 



E. longifolia, Lk, and Otto. E. eugenioides, Sieb. 



E. siderophloia, Benth. 



Caley was one of the first that made any progress in crossing 

 the Blue Mountains, and advanced as far as the place called 

 iC Caley's Repulse," marked by a heap of stones near Woodford ; 

 but all his specimens of Eucalypts were collected in what is now 

 known as the County of Cumberland. On his return to Europe, 

 he was offered by the King of Prussia £350 for his collection of 

 birds, but he refused the money and generously presented them to 

 the Linnean Society, as he thought it discreditable for them to go 

 out of England. 



It was not until the Blue Mountains had been crossed by 

 Wentworth, Blaxland, and Lawson in 1813, that the distin- 

 guished botanist and explorer, Allan Cunningham, had an oppor- 

 tunity of collecting specimens on the Mountains and beyond the
