To the following species, of which I have seen no authentic specimen, I have 

 nol been able from the descriptions alone to refer specimens examined by me. It 

 is probable that some of these ma}' prove identical with species described in the 

 following pages, but I am almost sure thai no species described bj' me as new 

 will turn out to be one of these unknown species: 



Aspidium Fischeri Mett. Aspid. 80, 1858; Dryopteris C. Chr. Ind. 266. — Brazil. — 



Judging from the description it is a very near ally of D. ptarmica, possiblj^ 



only a form of this species. 

 Aspidium paclujchlamys Fée, 11 mém. 77 tab. 21 fig. 2, 1866. — Guadeloupe, L'Her- 



minier 1861. — Seems to be a form of D. opposita. 

 Nephrodinm Sprucei Bak. Syn. Fil. 269, 1867; Dryopteris C. Chr. Ind. 294. — Ecua- 

 dor, Spruce. 

 Nephrodinm longicaule Bak. Journ. Bot. 18S1: 205; Ic. plant, tab. 1658; Dryopteris 



C. Chr. Ind. 275. — Columbia, Province of Antioquia, Kalbreyer n. 1454. 

 Nephrodium hrachypodum Bak. Trans. Linn. Soc. II. Bot. 2; 290, 1887; Dryopteris 



C. Chr. Ind. 255. — British Guiana, Mt. Roraima, im Thurn n. 225. 

 Polypodinm demeraranum Bak. 1. c. 290; Dryopteris C. Chr. Ind. 261. — British 



Guiana, Mt. Roraima, im Thurn n. 356. 

 Polypodinm roraimense Bak. I.e. 291; Dryopteris C. Chr. Ind. 289. — British Guiana, 



Mt. Roraima, im Thurn n. 168. 

 Polypodinm Crossii Bak. Ann. of Bot. 5: 455, 1891; Dryopteris C. Chr. Ind. 259. — 



Andes loxensis. Cross. 

 The following species described by Sodiro in Crypt, vase. quit. 1893: 

 Nephrodium brachypus Sod. p. 228, N. rigescens Sod. p. 239, N. conforme Sod. p. 240, 



N. elegantnlnm Sod. p. 243, N. semilunatnm Sod. p. 245, all from Ecuador. 

 The following described by Jenman in Bull. Depl. Jamaica 3 and 4, 1896 



-1897: 

 Nephrodium hasiattenuatum Jenm. (3: 20), N. caribaenm Jenm. (3. 21), N. crenu- 



laeum .lenm. (3: 68), Polypodinm Thomsoni Jenm. (4: 130), all from Jamaica. 



Polypodinm pnbescens Jenm. (4: 128) is hardly identical with P. pubescens 



Raddi and probably a species unknown to me.
