OBS. This genus is founded upon the Aspidium semi- 

 cordatum of Swartz, a native of the West Indies and some 

 parts of tropical America. It is closely allied to Nephro- 

 lepis, but differs in the vernation being fasciculate and 

 decumbent, and not stoloniferous, as also in the sori being 

 transverse biserial. A closely allied species is found in 

 the Malayan, Philippine, and other islands, the principal
