Hab. Tahiti, Society Islands. Ovolau, Feejee Islands : in moun- 

 tain forests. 



In specimens from the Feejee Islands the segments of the fronds 

 are longer and more attenuated, less falcate, with the apices more 

 dentate, rather than " serrate," as in the original form ; of which it 

 may be viewed as only a slight variety. The Tahiti specimens agree 

 perfectly with Willdenow's and Agardh's description.

Litobrochia decurrtns, Presl, Tent. Pterid. p. 149. 



Pteris decurrens, Raddi, Plant. Brasil. p. 48, t. 69 bis; Agardh. Gen. Pterid. p. 61. 



Hab. Organ Mountains, and vicinity of Rio Janeiro, Brazil. 



An admirable description is given of this by Agardh in his Recensio 

 Specierum Generis Pteridis ; to which we have nothing to add, save 

 that it is a very common Fern in the forests around the base of the 

 Corcovado.

5. Litobrochia macilenta, J. Sm. 



Litobrochia macilenta, J. Sin. in Hook. Jonr. Bot. 4, p. 163. 



Pteris macilenta, A. Rich. Bot. Voy. Astrol. p. 82, t. 12 ; A. Cunn. in Hook. Comp. 

 Bot. Mag. p. 365 ; Presl, Tent. Pterid. p. 145. 



Hab. Tippona, Bay of Islands, New Zealand : in woods. 



Presl, in his Tentamen Pteridographise, refers this to Pteris; but 

 it more properly belongs to his genus Campteria, in which the 

 lower venules anastomose. The figure of Pteris macilenta in the 

 Botany of the Voyage of the Astrolabe, it is true, represents a forked 

 venation, which circumstance may have misled Presl, as Richard, in 

 his description of the species, takes no notice of its lower venules 

 anastomosing.
