and the stipes stellato-pubescent, pinnse lanceolate obtuse 

 grandi-dentate or pinnatifid, the lowest abbreviated and as

 riculate at the base, superior ones adnate with' the base de- 

 current, uppermost confluent, sori uniserial on the segments 

 on the middle of the veins minute, involucres stellato-hir-

Hab. Cuba, Pceppig. — I possess a solitary specimen of this Nephrodium, from 

 Kunze, which well accords with his description. The two nos. 1005 and 1006 of 

 Wright's Cuba Ferns, referred to this, seem to me rather to accord with some of 

 the numerous forms of Nephrodium molle. 



11. N. (Eunephrodium) Jamesom, Hook.; caudex short erect 

 copiously rooting, stipites tufted 4-6 inches long patently 

 villous slightly and deciduously scaly, fronds 6-10 inches long 

 1-2 inches broad firm-membranaceous villous on both sides 

 oblong-lanceolate gradually acuminated upper half or nearly 

 so pinnatifid the rest pinnated, segments and pinnae oblong- 

 falcate obtuse coarsely and obtusely serrated (scarcely pinna- 

 tifid), the latter (pinnae) shortly petiolate the base truncated 

 subauricled above, lowest pair generally deflexed, base of the 

 costa with a large brown gland beneath, veins pinnated flex- 

 uose, veinlets remote simple or once or twice forked, 2-3 infe- 

 rior pairs united at very acute angles (subpleocnemoid), sori 

 in general copious in several series, involucres small hairy. 



Hab. Ecuador, near the River Napo, Jameson^ n. 761 ; Tarapota, Eastern Peru, 

 Spruce, n. 3916. — Had I possessed only one or two specimens of this Fern, I 

 might have been disposed to consider it an unusual state of N. molle ; but I have 

 half-a-dozen tufts from two widely-different localities, which are perfectly uniform. 

 It may be possibly related to Asjnd. dissidens, near to which I place it. This be- 

 longs as much to the next group of Eunephrodium as to the present. 



** Fronds pinnate, sometimes pinnatifid at the apex, and sometimes bipinnate 

 at the base. 



12. N. (Eunephrodium) dissidens, Metten.; "frond 8 inches

 sides as well as the costa and stipes (5 inches long), with
