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 P. turbinata La Liav. & 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.

anam ferrugineis margine straminellis; frondibus inter se propinquis 
6-12 em. longis 4-7.5 em. latis; stipitibus gracilibus 0.5-3.5 ci. 
longis exigue pilosis supra canaliculatis subtus semiteretibus ; lamims 
fere usque ad costam pinnatipartitis utrinque hispidulis atroviridibus 
circumscriptione valde variabilibus ovatis semiovatis vel aequilater- 
aliter triangulis prout segmenta duo inferiora reducta aut haud reducta

dilatatis confluentibus apice obtusis, maximis 6 mm. latis 3.5 cm. longis, 
terminale 1.5-6 cm. longo maxime variabili ; nervo mediano flexuoso, 
nervis lateralibus alternis utrinque 10-11 haud procul a basi furcatis, 
ramis anticis liberis in segmentis superioribus soriferis, ramis posticls 
arcuatis marginem nec attingentibus, aut simplicibus aut furcatis aut 
anastomosantibus areolarum seriem unam formantibus ; soris rotundis 
medio inter nervum medianum et marginem uniserialiter dispositis ca.

of Izabal, Guatemala, 11 February, 1905, @. C. Deam, no. 117 (type, 0 
hb. Gray). The same fern, collected by Tuerckheim at Cubilquitz, 
Department of Alta Verapaz, December, 1900, was distributed as 
Polypodium pubescens Hook. et Grev., in John Donnell Smith’s “ Plants 
of Guatemala,” no. 8053. P. pubescens 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
