460 Observations on Ferns 



14. P. Lunanianum, n. s. 



P. Lunanianum, frondibus pilosis late lanceolatis pinnatis, apice pinna- 

 tifido, pinnis lineari-lanceolatis attenuatis basi cuneatis subsessilibus obli- 

 que crenatis: infimis brevibus, soris biserialibus. 



Frons bipedalis. Stipes venaeque pilosi. Pinnae 4 pollicares, infimis 

 pollicaribus oblique crenatis. 



I have named this species after John Lunan, Esq., author of the 

 * Hortus Jamaicensis,' 2 vols. 4to., a work highly creditable to a colo- 

 nial press. 



This species is common in the woods near Wellington plantation, 

 Manchester. 



15. P. miser, n. s. 



P. miser, frondibus glabris deltoideis tri-pinnatis, pinnis alternis vel op- 

 positis lanceolatis, pinnulis primariis alternis, pinnulis secondariis subop- 

 positis profunde pinnatifidis, laciniis lanceolatis serratis remotis, soris mi- 

 nutis venis dichotomis terminalibus. 



Frons 3-4 pedalis glabris subtus resinose-glandulosa. Stipes 2 pedales 

 canaliculati. Pinnae pedales. Pinnulae primariae 2-3 pollicares. Pinnu- 

 lae secondariae pollicares distantes profunde pinnatifidffi. Laciniae serratae. 

 Sori venas dichotomas terminantes. 



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

 chester. This species is remarkable in bearing only a single frond at a 

 time from its root. 



16. P. effusum, Sw.; Sloane Jam., t. 57,/. 3; Willd. Sp. PI. 



vol. v. p. 208. 



Common at the sides of the roads which are cut through the woods 

 in the Mayday Mountains. 



Lomaria, Willd. 



L. ? longifolia, Kaul.; Plum. Fil. t. 117, fig, dextra ; Radd. 

 Fil. t. 73 ? Kaul. Enum. p. 152. 



I much doubt if this fern be a Lomaria, and am inclined to agree 

 with Willdenow, who places it in Acrostichum, for I have never satis- 

 fied myself that it has an indusium ; if it has one it must be very fu- 

 gacious. Lomaria fraxinifolia of Raddi I think is not distinct ; L. 

 fraxinea of Willdenow from the Mauritius I have never seen : he speaks 

 of it as very distinct from Acrostichum (Lomaria) sorbifolium, and as 

 having " indusia integerrima" 



This is a scandent fern, growing to a considerable height up the trunks 

 of trees, and rather common in woods in the Carpenter and Mayday 

 Mountains : I have it also from Trinidad. 



Antrophyum, Kaul. 



A. lanceolatum, Kaul. ; Schkuhr Crypt, t. 6 ; Kaul. Enum. 

 p. 198. 



This is scarcely an Antrophyum, for the sori are not immersed in 

 the substance of the frond.
