Polypodium gracilentum Jenm., Bull. Dept. Jam. n. s. 4: 129. 1897; Dryopteris 
gracilenta C. Chr. Ind. 268, which I believed (Revision p. 294) to be 
D. panamensis is not that species according to two pinn: of the type- 
specimen in the JENMAN collection in New York Bot. Garden, kindly 
sent me by Miss MarGARET SLosson. It may be a distinct species, 
allied to D. scalpturoides. The sori are apparently indusiate, but the 
indusia are very small with long hairs, which nearly completely con- 
ceal the young sporangia.

Area: Cuba, Jamaica. 
70. D. concinna (Willd.) O. Ktze.; C. Chr. Rev. nr. 1 fig. 2; Smiths. Misc. Coll. 52: 369.

71. Dryopteris rufa (Poir.) C. Chr. Ind. 290. 1905. 
Syn: Polypodium ruffum Poir. Enc. méth. 5: 532. 1804. 
Type from Peru, Lima (Herb. Lamarck, Mus. bot. Paris!); another speci- 
men from Lima, Warsow nr. 818 (RB) is perfectly typical. 
In my “Revision” pag. 274 I suggested this to be the Chilene form of D. ar- 
gentina, which is not the case. JD. rufa is a distinct species, in general habit 
resembling D. concinna and D. oligocarpa, well-marked by its setose sporangia 
as in D. concinna, but rachis and coste of both sides are sparsely pubescent by 
short hairs, not densely pulverulent as in D. concinna; leaf otherwise glabrous. — 
Lamina 40—50 cm long by 10cm wide, narrowed downwards as in the two species 
mentioned; pinnz opposite, firm; segments close, patent, acute; veins about 8 to a 
side; sori about medial; indusium not seen. 
72. D. Stierii (Ros.) C. Chr., Revision nr. 2 fig. 3. 
Area: Brazil, Rio Grande do Sul. 
73. Dryopteris blanda (Fée) C. Chr. Index 254. 1905. — Fig. 13.

Polypodium caespitosum Bak. Syn. Fil. 305. 1874. 
Dryopteris caespitosa C. Chr. Index 256. 1905. 
Type from Mexico, Mirador, leg. SCHAFFNER nr. 222 (specim. auth. in Kew). 
A small species, not unlike small forms of D. oligocarpa, but the lower pinnz 
not or very slightly reduced. — Rhizome erect or decumbent, small, scales very 
few. Stipes very slender, 15—20 cm long, stramineous, glabrous. Lamina 12—15 cm
