Stipes smooth ; fronds (many feet high,) alternately tri- 

 pinnatifid ; pinnae linear, fine serrate ; barren pointed, leaf- 

 lets ensiform ; fertile pointed, pinnatifid ; segments thereof

 a crowded line, near the margin of the segments. Involucre

Stipes smooth. Fronds (of a delicate texture, 2A feet 

 high,) alternately tri-pinnatifid ; pinnae linear, tapering to 

 most fine, long, serrate points ; leaflets of nearly the same 

 form, and deeply pinnatifid ; segments thereof linear, ser- 

 rate, with dentate apices. Fructifications remote and small, 

 in two rows of solitary spots near the base of each of the 

 segments of the leaflets. Involucre obscure.

 points ; leaflets ensiform^ fertile-pointed, to the base pinna- 

 tifid, segments thereof linear-oblong, incurved. Fructifica- 

 tions in a line of dots, on each side of the nerve of the seg- 

 ments of the leaflets. Involucre obscure.

 I cannot think Rumphins's Palmifilix, Hb. Amb. vol. 6, t. 

 27, is the same. 



42. P.felinum. R, 



Scandent. Stipes rough with minute prickles, (like the
