Kulin further states, that he himself had had in his 

 possession an original specimen of Robert Brown's, but 

 that, as in the case of the material in the Herbaria of 

 Hooker and Desvaux, the rhizome was wanting. At that 

 time, he had believed that the plant should be assigned to 

 the genus Allosorus [a genus, equally with Phorolobus (vide 

 supra), unrecognised in Ohristensen's " Index."] But more 

 recently he had received for determination a small collec- 

 tion of ferns from Lizard Island, on the north-east coast of 

 tropical Australia [Lizard Island is just above Oooktown], 

 in which numerous specimens of this plant were included; 

 and the result of his examination of the material had been 

 the confirmation of Mettenius' opinion, that the species 

 -constituted a new genus. 



Seeing that the " Botanische Zeitung" is difficult of 

 access in Australia, Kuhn's description of the new genus 

 {loc. ait.) may be advantageously reproduced in full:— 



Neurosoria Mett. nov. gen.
