2. Gymnogramma Chilense, Sp. Nov. 



G. frondibus pubescentibus lato-lanceolatis pinnatis ; pinnis sessilibus 

 ovatis obtusis pinnatifidis, lobis subrotundis integris vel dentatis. 



Hab. Chili, vicinity of Valparaiso; in fissures of moist rocks. 



Rootstock short, squaraose-hirsute. Stipes and fronds about equal 

 in length, together not exceeding 3 inches in height, everywhere 

 furnished with a pale pellucid pubescence. Fronds broadly-lanceolate, 

 obtuse, and pinnate. Pinnce subopposite, deeply pinnatifid; the inferior 

 ones distant and sessile, the superior adnate and decurrent on the 

 compressed rhachis. Sori becoming confluent, and covering the whole 

 of the under surface of the lobes. 



It is very probable that this is an already described species, yet we 

 do not find it in any work to which we have access. The species to 

 which it is most nearly allied, is the G. subglandulosum, of Hooker and 

 Greville ; from which, however, it differs in the smaller fronds, longer 

 stipes, more deeply pinnatifid pinnse, and in the nature of the pubes- 

 cence.

3. Gymnogramma pilosttm, Sp. Nov. (Tab. 4.) 



G. stipitibus glabris semiteretibus ; frondibus subcormceis basi bipinnatis 

 versus apicem pinnatis ; pinnis suboppositis oblongo-lanceolatis acumir 

 natis serratis basi incequalibus subtus costamque pilosis, inferioribus 

 petiolatis, superioribus sessilibus; venis ramosis, venulis furcatis. 



Hab. Sandwich Islands; in forests, by the banks of streams ; rare. 



Rootstock csespitose. Stipes about 20 inches long, of a pale straw- 

 colour, smooth, semiterete, and plane on the anterior side. Fronds 

 large, subcoriaceous, smooth on the upper, with scattered articulated 

 hairs on the under surface and costa, bipinnate at the base, and pinnate 

 towards the point. Pinnce subopposite, 6 to 8 inches long, by 12 to 15 

 lines broad, of an oblong-lanceolate form, narrowing gradually into a
