Remarks. The specimen of this fern in the Collection shows very clearly 

 the characters of the species. The pinnules are free and slightly rounded at 

 their base, the veins are very numerous, fine, and dichotomise twice. The 

 midrib of the pinnule is well defined. In form the pinnules are oblong, and 

 gradually narrowed towards their obtuse apex. None of the figures given by 

 Geinitz* as Alethopteris pteroides belong to Brongniart's plant. This fact has 

 already been pointed out by several authors.
