MARCH, igoo. PLANTVE UTOWAN^ MILLSPAUGH. 21 



Frequent on dry rocks near San Domingo city (812, 816). In rich soil 

 of a rocky glen near Port Antonio, Jamaica (897, 935, 1789, 1790). 



The above specimens are mostly rigid, pubescent forms, of which 

 816 is very large ; but 812 is quite flaccid, tender and sterile. 



No. 1789 is a small plant having two of its sterile fronds with 

 apical pinnae suppressed, the upper lateral pinnae on one of them 

 much elongated, and one small frond with the upper pair of pinnae 

 much elongated and the terminal one dwarfed into a small, roundish 

 cordate apex. 



No. 1790 is an unusually interesting plant, showing one frond with 

 a stipe a foot long bearing above several pairs of deeply pinnatifid 

 pinnae. The whole frond young and tender and resembling in form, 

 texture and pubescence a young Aspidium patens. This frond, if 

 detached from the parent plant, would never be considered to belong 

 to the species by any one. It is a remarkable variation similar to one 

 described* as having been found in Polypodium pellucidum. 



POLYPODIUM ACHILLE^EFOLIUM Kaulf. En. Fil. 1 1 6. 



Rich, open field near Port Antonio, Jamaica (911). 



The specimens do not fully answer to the description in Synopsis 

 Filicum (H. & B. 388), but agree so well with the illustration of this 

 species in Kunze's supplement to Schkuhr's Farnnkrauter, t. 43, f. 2, 

 that I am inclined to place them here. 



POLYPODIUM AUREUM Linn. Syst. Nat. 2:692. 



Deep mountain woods above Charlotte Amalia, St. Thomas (557). 

 Texture thin, areoles with flattened, free veinlets. 



POLYPODIUM LYCOPODIOIDES Linn. Syst. Nat. 2:691. 



Climbing Sabal trees near the Caleta, Cozumel (1534). 



POLYPODIUM PECTINATUM Linn. Syst. Nat. 2:691. 



Rare, in crotches of low trees near Port Antonio, Jamaica (896). 



POLYPODIUM PHYLLITIDIS Linn. loc. cit. 



In the crotch of a low tree on the high mountain back of Char- 

 lotte Amalia, St. Thomas (546). On an old stump near San Domingo 

 City (813). On trees near Port Antonio, Jamaica (999)- 



The only really distinctive character that I have been able to 

 find between this species and P. repens is in the rootstalk, and where 

 this is wanting it is not always certain in placing the specimens, as 

 the venation varies in different, and sometimes in the same plants. 

 Fournier, Mex. PI. Crypt. 85 makes P. repens Mett. a variety of this 

 species, and Shimek considered it a synonym. 



I have placed the above specimens here on account of their very 

 stout, almost globular rootstalk ; the venation in some instances cor- 

 responds to that of repens, and in others to typical Phyllitidis. The 

 rootstalk in repens should be long and slender. 



POLYPODIUM PILOSELLOIDES Linn, loc cit. 



Climbing the trunks and running the branches of trees, near Port 

 Antonio, Jamaica (1143).
