 & Prodr. 1, p. 34; A. Chum., Bot. N. Zeal, in Ann. & Mag. Nat. Hist. 4, p. 257; 

 Hook. f. Fl. N. Zeal., p. 11. 



Hab. Bay of Islands, New Zealand. 



The characters of this species given by DeCandolle are well com- 

 pleted by Cunningham. In our specimens the achenia, sometimes 

 12 or more in number, are manifestly compressed, and surrounded by 

 a sharp margin. The species is related to the preceding. 



6. Ranunculus acaulis, Banks & Sol. 



Ranunculus acaulis, Banks & Solander, 1. c.; DC., 1. c, A. Cunn., 1. c. ; Hook. f. 

 Fl. Antarc. p. 4. t. 2, & Fl. N. Zeal. p. 11. 



Hab. Bay of Islands, New Zealand. 



This species is admirably illustrated by Dr. Hooker, in his An- 

 tarctic Flora, from Aucklandian specimens, and is again described in 

 his Flora of New Zealand. 



7. Ranunculus hirtus, Banks & Sol. 



R. hirtus, Banks & Solander, 1. c.; DC. 1. c. p. 289; A. Cunn. 1. e. p. 259; Hook. f. 



Fl. N. Zeal. p. 9. 



Hab. Bay of Islands, New Zealand. 



This has smaller flowers, especially the petals, and more incised 

 leaves, with sharper lobes, than the following. I should suppose that 

 this was the plant which Richard and Cunningham referred to R. 

 aeris, notwithstanding the small flowers. But Dr. Hooker adduces 

 the synonym under B. plebeius.
