Very common by roadsides in the Carpenter and Mayday Moun-

I never saw this fern but once : it is very distinct from any Pteris I 

 have yet seen. 1 found it in the woods near Grant's Green plantation 

 on the western face of the Carpenter's Mountains, a few days previous 

 to my embarkation for England. It was the last fern I collected in 

 Jamaica.
