The history of this little fern, its variations in form, and its 

 geographical distribution, are of great interest to botanists. 



The plant was without doubt first recorded by Plukenet [Phy- 

 togr. //. 8g. /.p. 1 691] under the name Filicifolia s. Polypo- 

 diuui tcuuifolium uiinus Virgiuiauuiu, and later enumerated in 

 Almag. Bot. 153. 1696. Plukenet cites as a pos.sible synonym 

 " Caticad s. Polypodiuui Brasilicuse Pisouis [lib. iv., fol. 233] but 

 since the latter author describes his plant as having " caulcs 

 cubituui altiy its identity must be questioned. 



Polypodiuui radicc tciiui & rcpcutc of Plumier [Descr. PI. Am. 

 25,//. j(5. 1693, and Fougeres de I'Amer. 60. //. jy. 1705] 

 reported from San Domingo, and Polypodiuui uiiuus, etc. 

 [Sloane, Cat. PI. Jam. 16. 1696, and Nat. Hist. Jam. i : 79. 

 1707] refer also to our plant. Plumier says of this fern " J't^y 

 roicoutrt plusieurs fois cctte Plaute daus Ics forests de Pisle Saiut 

 Domiugue. C est le petit Polipode a piuuules rares & ceudries par 

 dessous du S*'. Sloaue Cat. Plaut. Jauiaic. 16." 



The name given to it by Morison [PI. Hist. 3: 563. sec. 14.
