Hab. Oware, tropical West Africa, Palisot de Beauvois. — This also is unknown 

 to me, and even the learned author desires to see better specimens to confirm tlie 

 sufficiency of the characters. It is certain, however, that the fragment figured 

 of the frond does not show it to be destitute of costa.

Hab. Sandwich Islands. Chamisso. — "Var. /3. "East Indies, Marianne Islands,

 Bhime." — I do not understand the limits of this species and V. zostercp folia. 

 Although the latter ought to be ecostate, the former costate, I find the costa to be 

 more or less evident in specimens which I should otherwise consider identical. 

 Specimens from the following localities stand in my herl)arium as V. rigida, Klfs.
