terete, with a single groove in front, and from 3 to 5 inches in length, 

 sparsely paleaceous at the base; the fertile one longer. Sterile and fer- 

 tile fronds usually about the same size, from 4 to 5 inches long, 

 smooth, very coriaceous, oblong-lanceolate, obtuse, attenuate at the base, 

 with a thickened entire margin.

Acrostichum aureum, Linn, ex Willd. Spec. PI. 5, p. 116; Kaulf. Enum. Fil. p. 65;

Hab. Tahiti, Society Islands. Samoan and Feejee Islands. Ton-

 for comparison, we have strong doubts whether they are distinct, 

 although Blume and Presl have retained them. Farther, we question 

 very much whether the A dancecefolium of LangsdorfF and Fischer 

 ought not to be referred here also?

The author of this genus founded it upon a solitary species from 

 the Philippine Islands; and it is with much satisfaction that we are 

 enabled to extend its geographical range, and to add what we con-
