64 NEPIIRODIUM, § EJINEPHRODIUM. 



6. N. (Eunephrodium) Skianeri, Hook. ; caudex erect or 

 ascending apparently proliferous clothed with the bases of 

 former years' stipites, stipites terminal tufted 2-4 inches 

 long with a few scattered scales, fronds submembranaceous 

 firm lanceolate finely acuminate deeply (more than halfway 

 down) pinnatifid, at the base pinnate, the apex entire, seg- 

 ments and pinnules oblong-ovate subfalcate rather acute 

 eiitire, veins numerous lowest pair united, sori small dorsal 

 between the costule and the margin, involucres reniform thin 

 and memliranaceous reticulated finely ciliated, rachis and 

 veins beneath pubescenti-hirsute. — Aspidium (Nephrodium) 

 Skinneri, Hook. Cent, of Ferns, t. 25. Ic. Plant, t. 925.

Hab. Gualeraala, Skinner. Bombinasa, Andes of Ecuador, Spruce. — Specimens 

 of this, recently sent from the Andes of Ecuador, by Mr. Spruce, precisely corre- 

 spond with those of Mr. Skinner. In the former country, it inhabits declivities 

 which are occasionally flooded ; and this circumstance perhaps explains the pro- 

 liferous appearance of the caudex or rootstock. 



7. N. (Eunephrodium) Wrightii, Hook. ; caudex creeping 

 branched paleaceous with dark-brown scales, stipites scattered 

 4-0 inches long rather stout stramineous dark-brown and 

 scaly at the base, fronds 6-7 inches to 1 foot long coriaceous 

 oblong-lanceolate short acuminate upper half or more deeply 

 (beyond the middle) pinnatifid, segments numerous oblong 

 obtuse 4 ^"^ i"ch to 1 inch long subfalcate entire, pinnae 

 oblong obtuse truncate at the base and often auricled above 

 and sometimes also beneath, the auricles acute, veins promi- 

 nent beneath whitish simple or forked, inferior pair combined, 

 sori marginal, involucres small reniform or lunate subci- 

 liate, rachis and veins beneath pubescenti-hirsute. (Tab.

Hab. Dense woods near j\Ionte Verde, eastern Cuba, C. Wright, n. 824. — 

 Eaton, who has well described this new species, notices its affinity with my Ne- 

 phrodium Skinneri, from which, however, it is extremely different, in its creeping 

 caudex, different form and texture of the fronds, the short acumen, and the mar- 

 ginal sori. 



8. N. (Eunephrodium) .^tenopteris, Hook. ; caudex short 

 stout ascending, stipites tufted 2-4 inches long scaly be- 

 low, fronds coriaceous 1-.2 feet long elongato-lanceolate 

 acuminate and often proliferous at the apex long-attenuated 

 and decurrent upon the stipes at the base, more or less 

 deeply pinnatifid most deeply above the middle with oblong-
