Mountains, near Old England plantation, and a second time in a field 

 of ruinate coffee, on the southern face of the same mountains, and much 

 nearer the sea : they were only small plants on each occasion. I think 

 it is not a plant of frequent occurrence. I have specimens of it from 

 Trinidad.

PI. vol. v. p. 436. 



The figure in Sloane is only pinnate, hut this species is more gene- 

 rally found hi-pinnate. 



Common hy roadsides in the Mayday and Santa Cruz Mountains. 



3. A. radiatum, Linn.; Plum. Fil. t. 100; Willd. Sp. PI. 



vol. v. p. 437. 



This pretty little fern is very common at roadsides in the Mayday 

 Mountains. 



4. A. cristatum, Linn.; Plum. Fil. t. 97; Willd. Sp. PL vol. 



v. p. 443. 



In similar places to the preceding. 



5. A. trapeziforme, Linn.; Sloane Jam. t. 59; Willd. Sp. PL 



vol. v. p. 447. 



This very beautiful fern is rather common in the open forest land in 

 the Mayday Mountains. It has a most elegant appearance from the 

 contrast of its delicate green pinnulse with the shining black stipes and 

 rachis. 



6. A. tenerum, Sw.; Pluk. Aim. t. 254, /. 2.; Willd. Sp. PL 



vol. v. p. 450. 



Frequent in cleared land in the Santa Cruz and Mayday Mountains. 

 The Adianti of Jamaica appear to prefer more open land than the ge- 

 nerality of ferns ; they are more commonly found in exposed situations, 

 as road sides and sunny banks, than most other Filices.
