incised; the apices of the segments emarginate, bearing oblong sari. 

 Indusiwn hairy. Whole plant furnished with articulated fulvous

4. Adiantum obtusum, Desv. 



Adiantum obtusum, Hook. & Grev. Ic. Fil. t. 188 (opt.); Hook. Spec. Fil. 2, p. 19. 



Hab. Brazil : in woods, on the Corcovado, Rio Janeiro, and Organ 

 Mountains. 



This does not in any way differ from the plant figured in the Icones 

 Filicum, which is said to have been received from the Island of Trini- 

 dad. May not the Pteris adiantoides of the Flora Fluminensis, 11, t. 

 88, be an indifferently executed figure of this species ? 



5. Adiantum Capillus Veneris, Linn. 



Adiantum Capillus Veneris, Linn.; ex Willd. Spec. PI. 5, p. 449; Gaud. Bot Freyc 

 Voy. p. 404. 



Hab. Island of Madeira. Sandwich Islands : in fissures of moist 

 rocks. Sea-coast near Hilo, island of Hawaii. Valley of Nuuanu, 

 island of Oahu : on the banks of streams. 



Gaudichaud also detected this species at the Sandwich Islands. 

 We have made a careful comparison of specimens from the latter 

 country with those of the A. Capillus Veneris collected by us on the 

 Island of Madeira, and find the two to be in every respect alike; 

 which is farther evidence of the great geographical range of some 

 species of Ferns.

Adiantum scabrum, Kaulf. Enum. Fil. p. 207; Hook. & Arn. Bot. Beech. Voy. p. 53.
