ensiform, base truncate, with the upper angle thereof rather 

 enlarged, the fertile crenulate. Fructifications large, in a line 

 near the margin. Involucre round. 

 Nat. of Amboyna. 



13. P. rupestre. R. 



Petioles smooth ; fronds pinnate, (3-4 feet high,) smooth ; 

 leaflets subalternate^ narrow-lanceolar, scarcely crenate. 

 Fructifications solitary, (forming a line on each side the 

 nerve, of rather remote dots.) Involucre obscure. 



Nat. of Pinang, on mossy shaded rocks of granite. 



14. P. radicans. Burnt. Aspidium auriculatum Sw. Wall.

Scandent, and supported by tendrils or roots, from short, 

 remote, scaly, frond-bearing shoots. Fronds pinnate ; sterile 

 leaflets oblong; fertile ensiform, with base truncate, and 

 there enlarged on the upper angle ; all are obtuse. Fructi- 

 fications in a line near the margin. Involucre round-reni- 

 form. 



P. radicans. Burm. FL Ind. 233. t. 66. /. 3. is not un- 

 like the sterile frond, and was most likely intended for the 

 same plant. 



Nat. of the Malay Islands^ &c. 



15. P, unitum. Burm, Icon. Roxb. 14, t. 100. 



Stipes smooth; fronds (2-3 feet high,) pinnate; leaflets 

 barren and fertile alike, ensiform, serrate, villous under- 

 neath. Fructifications generally scattered, and nearer the 

 margin than the nerve. Involucre ciliate.

I doubt if this is Desfontaine's Barbary plant. His des- 

 cription does not well accord with our East Indian species. 

 Here our leaflets are not pinnatifid, but serrate, with a 

 single line of distinct spots, a little removed from the mar- 

 gin. It is probably a Davallia or Dicksonia. Unfortunately 

 I neglected examining the involucre when I had it in my 

 power.
