 Hooker, who is familiar with it in its head-quarters of New Zealand and Tasmania, 

 says, " It is quite in vain to attempt to limit this and its allied species {A. flaccidum) 

 by words." I do not, however, share with that author in the ojjinion of its too 

 close proximity to A. flaccidum ; still less that it passes into J. adianloidcf, liaoul 

 (//. Hoolerianum of this work) : at least, my own specimens do not lead me to 

 such conclusions. The Aspl. viridansoi Austro-Caledonia may, I think, be safely 

 united to this. It will surprise many that I bring under this species the Aspl. 

 bullatum of Wallich, Cat. n. 215 ; and still more, perhaps, that I refer here what 

 I consider the same species from tropical regions of the New World : the differ- 

 ences are too trifling to justify me in keeping them distinct.
