"brought from the Island of Jamaica. 459 



Very common on stone walls in the Mayday Mountains. 



7. P. incanum, Sw.; Schkuhr Fil. t. 11, b; Willd. Sp. PL 



vol. v. p. 174. 

 Generally growing with the last-named species, or with Cheilanthes 

 microphylla, in similar situations. It varies much in size. I have it 

 also from Trinidad, Brasil, and Sierra Leone. 



8. P. sporadocarpum ? Willd. ; Willd. Sp. PI. vol. v. p. 171. 

 This fern has very much the habit of P. aureum, except that the 



lacinise of the fronds are broader in the middle, and much closer toge- 

 ther :' it belongs to a section of Polypodium extremely difficult to de- 

 termine without accurate figures. I mostly found it growing about 

 the spurs of large trees, in open districts in the Mayday Mountains. 



9. P. loriceum, Linn. ; Plum. Fil. t. 78 ; Willd. Sp. PL vol. 



v. p. 176. 



Found generally in the same situations as the preceding, but occa- 

 sionally in the woods. 



10. P. simile, Linn.; Sloane Jam. t. 32; Willd. Sp. PL vol. 



v. p. 192. 



Common on living trees in the woods near Wellington plantation* 

 on the western face of the Mayday Mountains, where it has a very 

 graceful appearance as it hangs down, the stipes being slender, and 

 unable to bear the fronds erect. 



11. P. reptans, Sw.; Sloane Jam., tt. 29, 30; Willd. Sp. PL 



vol. v. p. 186. 



Growing in a damp ravine in the woods near Old England planta- 

 tion, Manchester. 



12. P. Smithianum, n. s. 



P. Smithianum, frondibus pilosis late-lanceolatis pinnatis, pinnis lance" 

 olato-acuminatis subsessilibus profunde crenatis oppositis vel alternis, pin- 

 nis terminalibus petiolatis, venis stipiteque pilosis, soris medio venarum in- 

 sidentibus. 



Frons sesquipedalis pilosa. Pinnae 4-pollicares profunde crenatis. Sori 

 pilosi. 



I have great pleasure in dedicating this species to my old and valued 

 friend Mr. John Smith, the able Curator of the Royal Botanic Garden 

 at Kew, who has for many years successfully dedicated his time to the 

 growth of this most interesting family. 



Common in the woods on the western face of the Mayday Mountains; 

 I have specimens also from Trinidad. 



13. P. crenatum,Sw.; Plum. Fil. #.111; Willd. Sp. PL vol. v. p. 



189. 



Frequent in the mountain woods near Old England plantation, Man- 

 chester. I have this also from Trinidad.
