instructa, niembranacea vel subherbacea, colore brunnea, bipinnatifida. Pinnis 

 30 — 35 jugis, inrerioribus oppositis vel siiboppositis, superioribus alteniis, sessilibus, 

 2'/-' cm. inter se distanlibiis, horizontalibiis, inferioiibus 6 — 7 jugis subgiadatim 

 reductis, reflexis, imis niinimis, auiiculiformibus, niedialibus maximis, lineari- 

 lanceolalis, c. 12 cm. longis, l'icm. latis, ad apicem acuminatum sensim attenuatis. 

 Laciniis c. 30 jugis, oblongis, obtusis vel subacutis, obliquis nec falcalis, integris vel 

 leviler répandis marginibus pauluni revohUis, ala vix 1 mm lata connectis, sinubus 

 rotundis, basali anteriore ceteris aequali, posteriore saepe longiore et angustiore. 

 Venis 7—8 jugis, indivisis, pellucidis. Soris supramedialibus; indusiis deciduis, 

 dense setosis. 



This species is only to be compared with D. pilosiila, resembling it in pube- 

 scence, but its whole habit, its longer and broader lamina, brown colour, densely 

 red-haired racliis, its very scaly base of the stipe and its deciduous indusium make 

 it very diflerenl from all the si)ecies of this group.

Syn. Ncphrodiiim Nocldanum Jenman, Journ. Bot. 1886 : 270 ; Bull. Dept. Jamaica 

 n. s. 3: 21. 1897. 



Type specimen from Jamaica (non vidi). — A specimen from the same 

 island: Mt. Diabolo, leg. W. B. Maxon n. 1879 (HC) and determined by Maxon as 

 D. Nockiana agrees peifectly with Jen man's description. I have had some doubt 

 whether this species is different from /). panamensis, but as it differs from that 

 species in some essential characters I find it proper to let it stand as a distinct 

 species. 



D. panamensi vakle similis, difl'ert: stipitibus longioribus cum rachibus graci- 

 lioribus breviter pubescentibus, pilis longis destitutis. Pinnis alternis, 4V-' cm. longis, 

 vix 1 cm. latis, supra ad costas venasque sparse pilosis, subtus dense glandulosa, 

 glandulis aureis. Laciniis parum obliquis, nec falcatis, basalibus produclis, posteriore 

 auriculata. Venis 4—6 jugis. Soris supramedialibus. Indusiis magnis, persistenti- 

 bus, setosis. Textura herbacea, lamina pellucida. — Etiam D. oliyocarpae valde 

 similis, a qua specie diffcrt: lamina subtus dense glandulosa, indusiis pcrsistentibus.
