POLYPODIUM REPTANS SwtZ. Fl. Ind. OcC. 1655. 



Completely lining the throat of an old well near Georgetown, 

 Grand Cayman (1398). Plants mostly juvenile. 



POLYPODIUM TETRAGONUM SwtZ. loc. cit. 1760. 



Moist, rich banks, foothills at Bayamon, Porto Rico (347, 351, 

 353). Moist, rich woods on the mountain heights above Charlotte 

 Amalia, St. Thomas (547, 553)- Rich woods near Port Antonio, 

 Jamaica (1148), sterile, with large pinnae. 



Mr. Baker, in his recent Synopsis of Brazilian Ferns, has 

 adopted Poiret's older name Androgynum for this species, but, as I 

 have not been able to investigate this to my own satisfaction, I have 

 retained here the Swartzian name which has been in use for nearly 

 a century. Mettenius referred this, as well as P. reptans, to Phe- 

 gopteris, in which he has been followed by Prof. D. C. Eaton and 

 others, but I can only look upon both these as true Polypodia^ of the 

 Goniopteris section. 



Polypodium thysanolepis A. Br. ex Klat. in Linn. 20:392. 



Quite large specimens, on trees near Port Antonio, Jamaica 

 (890, 1787). 



Polypodium vacciniifolium Fisch. & Lang. Fil. 8, t. 7. 



Climbing small saplings on a hillside near Bayamon, Porto Rico 



(307)- 



Imperfect specimens only, and somewhat doubtfully belonging 

 here, but not safe to place elsewhere. My specimens resemble a 

 smooth form of piloselloides. 



Acrostichum aureum Linn. Sp. PI. 1525. 



In a bog near Paget's, Bermuda (52). In a brackish marsh east 

 of Port Antonio, Jamaica (953). Springy bog in the center of the 

 island Grand Cayman (1377). Also seen in the open mangrove swamp 

 between Cataiio and Bayamon, Porto Rico, but could not be reached. 



No. 52 presents the upper portion of fertile frond with 14 pairs 

 of erecto-patent obtuse pinnae and bifid apex ; no. 1377 consists of 3 

 large sterile pinnae on rachis a good inch in circumference, and a 

 portion of a fertile frond with 6 pairs of pinnae, mostly with acute or 

 cuspidate apices, but some obtuse, a good example of the non essen- 

 tial character of the apical termination. No. 953 gives portions of 

 fertile and sterile fronds, bright green in color ; pinnae on the sterile 

 frond long and narrow, suberect, obtuse, with cuneate stalked bases; 

 those of the fertile frond sterile below and twice the length of the 

 upper fertile ones. 



SCHIZiEACEiE. 



Anemia adiantifolia (L.) Swtz. Syn. 157. 



Dty banks near Bayamon, Porto Rico (315, 358), and same situ- 

 ation near Port Antonio, Jamaica (910, 917). Near limestone boul- 

 ders in open woods, center of the island, Cozumel (1563). 



The series shows quite a range in the size of the fronds, of which 

 those of No. 917 are very large and fine.
