The plant from St. Thomas's bland was named l>y Sir William 
Hooker A. fluviatile, but Welwitsch points out that it is obviously 
only a form ami not a variety of .1. punctatum. Ii has the main 
veins distinct, and consequently belongs to the Grymnqpteria section 
of bhe genus.

Welwitsch and Mettenius considered this fern should rank as a 
distinct speries. Welw itsch separates it because the fronds are impari- 
pinnate to the apes ; bhe pinnee are distinctly petiolate, and a bulbil 
is found at the base of the last pinna. The pinna; of the upper part 
of the frond are Bubsessile ; they have in the barren frond long acumi- 
nate apices, while the pinme of the fertile fronds are three or four 
times narrower, and shortly acuminate. 
In all essential characters this plant so closely agrees with A. punc- 
tatum that it seems to deserve a place only as a variety of that species.

This fern is nearly allied to A. contaminans Wall, one of the species 
included by Mr. Baker in .1. virens Wall. In .1. contaminans bhe two, 
three, or four secondary veins run out from the vein free, while in 
the African species the meshes of the secondary veins continue to or 
almost to the margin, and only the veinlets reach the margin free.

without doubt a halophybe.
