brought from the Island of Jamaica. 457 



Acrostichum, Linn. 



1. A. aureum, Linn.; Plum. Fil. £.104; Willd. Sp. PI. vol. v. 



p. 116. 



This noble fern is very plentiful in morasses and water-courses in the 

 lowlands of Jamaica. It grows from 8 to 10 feet in height. I never 

 found it at any great elevation above the sea-shore. 



Milk River, &c. Jamaica. 



2. A. nicotiarHefolium, Sw. ; Willd. Sp. PI. vol. v. p. 118. 



Generally found at the margins of woods. The barren frond is of a 

 very bright green while growing, and the texture rather delicate. 

 Mayday mountains. 1 have it also from Trinidad. 



Gymnogramma, Desv. 



1. G. Love it, Hook. & Grev. ; Icon. Fil. t. 89. 



This fern, which I have little doubt of being the same as the one fi- 

 gured in the splendid work quoted above, is an instance of the wide 

 range of habitats of ferns ; for the plant from which the figure was ta- 

 ken came from Madeira, growing at a height of between 2000 and 3000 

 feet; my specimens were found at about the same height, in the May- 

 day mountains. 



2. G. gracile, n. s. 



G. gracile, frondibus pilosis lanceolatis elongatis bipinnatifidis, pinnis 

 lanceolatis attenuatis alternis : infimis brevibus, laciniis linearibus apice 

 rotundato crenato. 



Frons 2-pedalis utrinque pilosa. Pinnae 4-6 pollicares pinnatifidae. La- 

 ciniae 6-lineares apice crenato. Sori insidentes venis secondariis simplicibus. 



I found this fern in the mountain woods in the parish of Manchester, 

 Jamaica, at the same elevation as the preceding species. It is not very 

 common. 



3. G. tartarea, Desv.; Willd. Sp. PI. vol. v. p. 131. (Hemi- 



onitis dealbata). 



This and the following species I found growing in a marl-pit, in the 

 same wood where I had previously found the two other species of this 

 genus. 



4. G. calomelanos, Kaul. ; Plum. Fil. t. 40; Kaul. Enum. p. 76. 



I think starved specimens of G. calomelanos often go under the name 

 of G. tartarea. 



Grammitis, Sw. 



1. G. etongata, Sw.; Spreng. Crypt, t. 3. Jig. 21 ; Willd. Sp. 

 PI. vol. v. p. 140. 



Generally to be found on decaying trees in the deep mountain woods. 

 Manchester.
