Remarks. — Psomiocarpa is so closely related to Dryopteris that one 

 is tempted to consider its several species as aberrant Acrostichum- 

 like forms of this g^enus, with condensed non-indusiate sori. On 

 account of the shape of the sterile frond and of the scales, the two 

 American species are more closely x€[2X^^ \.q \\\z Lastrea pinnata 

 group of Dryopteris. while the only other species, from the Far 

 East, with its compound frond and its hairs, comes nearer to the 

 species of the Lastrea decomposita g'roup, as. for instance, D. dissecta 

 (Forst.).
