196 Underwood: American ferns 



Asplenium erosum L. Syst. Nat. ed. 10. 2 : 1324. 1759. 

 (Type from Jamaica, based on Sloane, Voy. Jam. 1 : pL 



33- /• *•) 



Central Florida : Cedar hammock, Sumpter County, 1894, 



F. L. Lewton. 



This is the plant reported by Mr. Maxon in Torreya 3 : 185. 

 1903, and referred to a form of A. auritum Svv., and it represents 

 one of the forms usually referred to that name from various West 

 India islands. We have material similar to the Florida plant at 

 least from Cuba, Jamaica, Hispaniola, and Porto Rico ; much of 

 the Jamaica material, however, which has been referred to A. 

 auritum, is of quite a distinct type. In establishing A. erosum, 

 Linnaeus based his name wholly on Sloane's plate ; the plant of 

 the present type, which agrees in every essential with Sloane's 

 plate, must bear the name A. erosum, and, for the present, it will 

 be left an open question as to whether all the so-called A. 

 auritum Sw. of the West Indies and Mexico shall be merged under 

 this name. It should be noted thatSwartz cited the same plate of 

 Sloane in establishing his Asplenium auritum, but in this case there 

 is probably a specimen in Swartz's herbarium which will naturally 

 take precedence of a cited plate in determining the type of the 

 species. The name Asplenium erosum has unfortunately been used 

 by various writers for species widely different from the one to which 

 the name was originally given. We are fortunate to be able to 

 get back to a real foundation for the application of the name. 

 Sloane's plant is preserved in the British Museum.
