Oss.—In 1851 Fée separated the species of this genus 
— from Tenitis, and constituted of them the genus Cuspidaria; | 
but as that name had been previously occupied by both 
. Link and De Candolle for two plants of different orders, 
 ltherefore in the “ Botany of the Voyage of the Herald” 
 Substituted the above name. Fée enumerates three species, - 
two of which I adopt; the third having fasciculate adherent ` 
 vernation comes under the genus Pteropsis, In habit and ` 
texture of the fronds, the species of this genus, seem Jo 
mark their relationship to be with Pleopeltidec, but differ 
in the venules anastomosing, forming arches near the 
‘margin, on which the sporangia are produced. ils
