1220 m., 17 October, 1900, C. G. Pringle, no. 9253 (type, in hb. 

 Gray). This species is clearly separated from the preceding by its 

 much narrower leaves and merely puberulent more subulate involucral 

 scales. It belongs to a group of several obviously diverse yet nearly 

 related plants which have been provisionally referred to the merely in- 

 ferential F. turhlnata La Llav. & Lex. The latter, however, described 

 as having ovate leaves and short-peduncled heads, must certainly have 

 been a plant quite different from either here characterized.

 of Izabal, Guatemala, 11 February, 1905, C. C. Deam, no. 117 (type, in 

 hb. Gray). The same fern, collected by Tuerckheim at Cubilquitz, 

 Department of Alta Verapaz, December, 1900, was distributed as 

 Polypodium puhescens Hook, et Grev., in John Donnell Smith's " Plants 

 of Guatemala," no. 8053. P. jmbescens is, without doubt, the nearest 

 related species to P. hispidulum. It has, however, a much larger frond, 

 with irregularly laciniate segments, which at the base of the frond are
