200 Underwood : American ferns 



discrepancies noted were due to the inaccuracy or possibly ideal- 

 ization of Plumier's artist. With the now abundant collections at 

 hand from all parts of the West Indies there is no longer a doubt 

 that we have two very excellent species and that Plumier's artist 

 is again justified. Our Florida species (ranging throughout the 



West Indies) is Tectaria heracleifolia (Willd.). ( Aspidium lura- 



cliifolium Willd. Sp. PL 5 : 217. 1810; type from Hispaniola, 

 based on Plumier plate /.//, which is an extreme form of the 

 species.) 



This species has uniformly peltate indusia. The true Tectaria 

 trifoliata (L.) Cav. has indusia varying on the same plant from ren- 

 iform with a very broad sinus to circular with a mere emargination 

 on the side, thus breaking down the supposed distinctions between 

 Tectaria and Sagenia as hitherto maintained. The true T. trifoli- 

 ata ranges from Cuba (where we have collected it on El Yunque) 

 and Porto Rico to Guadeloupe, Martinique, Dominica, St. Vin- 

 cent, and Grenada. It differs in texture, form of lobes, venation, 

 and indusia, and many of its characters were clearly portrayed in 

 1703 by Plumier, whose illustrations can now be easily interpreted 

 with ample material of both species at hand.] 



Tectaria coriandrifolia (Sw,). 



Aspidiutn coriandrifoliutn Sw. Jour. Bot. Schrader 1800 2 : 36. 

 1 80 1. (Type from Jamaica, citing Pluk. Aim. pi. 284.. f. 5.) 



Florida: 14 miles south of Cutler, 1903, A. A. Eaton j6j. 

 The Florida plants are smaller and somewhat less divided than 

 the ordinary Jamaican forms, while the plants from Cuba are quite 

 intermediate between them. 



Odontosoria clavata (L.) J. Sm. Hist Fil. 264. 1875. 



Adiantutn cl ova turn L. Sp. PL 1056. 1753. (Type from San 



Domingo, based on Plumier's pL ioi. f. b.) 



Davallia clavata Sw. Syn. Fil. 123. 1806. 



Southern Florida : 1 2-20 miles south of Cutler, A. A. Eaton. 

 Already reported by Mr. Katon (cf. Fern Bull. 12 : 47). 



The discovery of this species in Florida adds the third repre- 

 sentative of its tribe {Davallieae) to our flora. The narrow trun- 

 cate and almost cuneate segments make it an easily recognizable 

 species. We have gathered the fern in Cuba, Porto Rico and
