Rhizomate crasso, erecto, squamis rufis, mollibus, lanceolatis vel ovato-lanceo- 
latis, marginibus pilis capitatis glanduliferis (sessilibus vel pedicellatis! dense vestito. 
Stipitibus fasciculatis, 8—12 cm longis, brunneo-stramineis. Lamina coriacea vel 
membranacea, ovata vel ovato-lanceolata, 10—-15 cm longa, 8 cm lata, 
4-pinnatifida. Rachibus paleis filiformibus deciduis paucis preeditis. 
Pinnis pinnulisque densis, ultimis (IV ordinis) obovatis, 3—4 mm 
longis, 1—2 mm latis, obtusis vel subacutis, integris vel obtuse 
dentatis, interdum sublobatis. Venis indivisis furcatis vel subpinnatis. 
Soro singulo pro segmento; indusio subpersistente, reniformi; sporis 
breviter verruculosis. 
A critical species, perhaps a high-andine variety of D. dentt- 
culata; still it differs from all forms of that species by its soft, 
rufous, glandulose scales and its obtuse segments, As to these 
characters it resembles the following species, which, however, is

Type from Cuba, leg. Linpen nr. 2115! (RB). 
A large species allied to D. denticulata, in habit and much divided lamina 
closely resembling some forms of that species especially var. barbensis, but well 
marked by some essential characters: 1) the scales of the rhizome are yellowish or 
reddish brown, opaque, thin and soft, ovate-lanceolate or lanceolate, not glandulose, 
2) the ultimate segments are lanceolate with obtuse teeth or lobes, and 3) the 
spores are smooth, not papillose. ? 
Rhizome short, erect, scaly. Lamina ovate or ovate-deltoid in the largest 
specimen seen 40 cm long on a stalk 45cm long, but as a rule smaller, firmly 
herbaceous, rather flaccid, perfectly glabrous, 4-pinnate—5-pinnatifid. Basal pinne 
25 cm long with the lower side somewhat produced. Sori at maturity nearly filling 
the whole segment; indusia dark-brown, reniform, subpersistent.
