Specimens of this Fern were communicated by Dr. Kraus from Dominica. It has a near affinity, 
certainly, with the 77. sinuosum ; but our plant is much smaller, more deeply pinnatifid, and with 
more divided segments. "The 77. incisum of Kaulfuss approaches it in size and general habit; but 
that species seems to us scarcely distinct from the true 77. Simuosum.
