192 POLYPODIUM, § EUPOLYPODIUM. 



71. P. (Eupolypodium) tenuifolium, H.B.; caudex repent 

 short tliickish in age and clothed with beautifully crisped 

 ferruginous scales, stipitcs remote 1-4 inches long rather 

 stout erect, fronds 8-12 inches long 2 inches broad firm- 

 membranaceous glabrous or very slightly pubescent on the 

 rachis and costules beneath broad-lanceolate acuminated 

 scarcely at all attenuated at the base pinnated (rather than 

 pinnatifid), pinn£E horizontally patent distant h an inch apart 

 1-U inch long 1 line wide linear obtuse moderately decur- 

 rent (hence a little l)roader at the base) quite entire or 

 obtusely sinuato-dentate, costule slender sinuate, veins erecto- 

 patent simple or forked, sori slightly sunk in a cavity 6-10 

 on each side the costule and occujjying the space between it 

 and the margin. — Himih. and Bonpl. Nov. Gen. i. p. 9. IVilld.

Ilab. St. Domingo, Plumer. New Granada, //jonioW/ and Bonplan(l,Jurgen- 

 sen, n. 664. Cuba, Linden, n. 1886, C. Wright, n. 809.— Probably a rare species, 

 well figured, liowever, by Fee, under the name of campfoneuron. The fronds, 

 as well as the stipites, are quite erect and firm, but not at all coriaceous. 



72 P. (Eupolypodium) pteropus. Hook. ; caudex a small 

 scaly rhizome densely rooting with copious fibres suberect, 

 stipites terminal ccespitose very short 2—4 lines often none 

 (in other words the stipes is winged with dwarfed lobes or 

 segments to its very base slightly hairy), fronds firm-mem- 

 branaceous or even subcoriaceous erect 4-18 inches long 1-3 

 or more inches wide glabrous more or less opaque or sub- 

 pellucid lanceolate acuminate singularly contracted and de- 

 current below deeply almost quite to the base pinnatifid 

 rarely subpinnate, segments remote linear and often elongato- 

 linear obtuse or subacuminate entire (not lobed or sinuated) 

 their base broad and much decurrent when within a few 

 inches of the stipes suddenly dwarfed much dilated above 

 and below and forming shallow lobelike wings reaching to 

 the caudex, rachis and costule black, veiiis short oblique 

 numerous each bearing a small slightly sunk oval or sub- 

 rotund sorus rather nearer the costule than the margin.
