10. C. dhergens, Kze. ; base of the stout st. muricated, fuvfuraceo-tomentose 

 and scaly (on the upper side) with firm, intensely black, lanceolate, very long- 

 pointed scales having a pale margin ; fr. large, glabrous, bipinnate, petiolate ; 

 pinnl. firm-coriaceous, 4-6 in. 1., 1-li in. \v,, from a broad base oblong, acuminate, 

 deeply jtinnatifid ; lobes rather distant, oblong-falcate, acute, subserrated ; sori 

 costal, numerous ; invol. membranaceous, fragile, soon breaking in a very irre- 

 gular manner. — Hk. .S/>. \. j). 19. t. 11. A.

 " Caud. arboreous, 40 ft. high, 1 ft. iu diam. Fr. 7 ft. long, including the stipes. Piunce 

 12 on each side, excluding the few minute terminal ones." Spruce. 



11. C. gracilis, Griseb. ; st. strongly muricated at the base ; /;•. bipinnate, 

 ^glabrous ; prim, and second, pinnce long-petioled, deltoideo-acuminate, the latter 



3-4 in. 1., 1-1^ in. w. at the base, deeply pinnatifid ; lobes oblong, obtuse, serrated ; 

 sori copious, generally confined to the superior half of the lobes ; invol. dark-

 —Griseb. Ft. B. W. Ind. p. 704. 



Hab. Jamaica, Wihon, Purdie. Antioquia, Jervise. — Allied, as Dr. Grisebacb says, 

 to C. divergens, but very distinct. A peculiar feature is given to this plant by the 

 unusual length of the petioles, geneially 2-21 in. 1., and by the pinnules being truncated 

 at the base. 



12. C. Mettenii, Karst. ; " caud. arborescent bald (not clothed with the bases 

 of old leaves), squamose above ; st. brunneo-squarrose at the base, unarmed ; fr. 

 lanceolate, 6 ft. and more long, 3-4 ft. w., ovate-lanceolate, acute, bipinnate ; 

 pinnl. 2 in. 1., from a broad base lanceolate, deeply pinnatifid, deciduous ; costce 

 and veins on both sides squamoso-pilose ; lobes falcate, oblong, obtuse, obsoletely 

 serrated, glaucous beneath ; veins generally forked, soriferous at the fork ; 

 invol. globose, breaking open irregularl}-." — Karst. Fl. Columb. \, p. 113. t. 56. 



Hab. Andes of Bogota, alt. 8-9,000 ft., Karsten. — Like a small subglabrous form of 

 Schanschin, clothed with scales on the ribs of the segments beneath.

 muricated ; pinnce oblong-lanceolate, 1^-2 ft. 1.; pinnl. sessile, 4-4J in. 1., | in.

 hairy on the ribs ; veinlets 10-12-jugate, forked; sori costular ; mw/. glabrous, 

 breaking up irregularly. — Fl. Columb. 1. t. 09. 



Hab. Andes of Columbia. — Beautifully figured, as are the preceding and the two next, 

 in Karsten's magnificent Selections from the Columbian Flora.

 slightly furfuraceous with a few raised points ; pinnos oblong-lanceolate, 1^-2
