10. C. divergens, 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., 1-1^ in. w., from a broad base oblong, acuminate, 

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

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

 gular manner. Hk. tip. 1. p. 19. t. 11. A. 



Hab. Peru, Ecuador, alt. 11,000 ft., Spruce, n. 5367. N. Grenada, Schlim, n. 480. 

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

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



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

 glabrous ; prim, and second, pinnae 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- 

 brown, bursting into somewhat regular valves or lobes to near the cup-like base. 

 Griseb. FL B. W. Ind. p. 704. 



Hab. Jamaica, Wilson, Purdie. Antioquia, Jervise. Allied, as Dr. Grisebach says, 

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

 unusual length of the petioles, generally 2-2J 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 irregularly." Karst. Fl. Columb. 1. 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. 



13. C. squamipes, Karst. ; fr. ample, tripinnatifid ; rachis grey-stramineous, 

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

 br. ; segm. close, flat, in. br., obscurely toothed ; texture firm ; under surface 

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

 breaking up irregularly. Fl. Columb. 1. 1. 99. 



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

 in Karsten's magnificent Selections from the Columbian Flora. 



14. C. incana, Karst. ; fr. ample, tripinnatifid ; rachis grey-stramineous, 

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

 ft. 1. ; pinnl. sessile, 3 in. 1., ^ in. br., cut down to a broad wing ; segm. in. br., 

 falcate, subacute, denticulate ; texture subcoriaceous ; iipper surface dark-green, 

 glossy, glabrous except the ribs, lower with minute fimbriate scales on the mid- 

 rib ; veinlets 8-9-jugate, forked ; sori costular j invol. small, densely pilose.

15. C.frondosa, Karst. ; " caud. lofty, unarmed, squamose with linear-subulate 

 sca/es, acuminate, frondose at the summit ; ft: ovato-lanceolate, 12-14 ft. 1. by 

 6 ft. w. ; pinnl. 4-5 in. 1., from a broad base lanceolate ; lobes oblong, margins 

 recurved, penniveined ; veins forked, their branches clavato-incrassate at the
