5. C. serra, W. ; st. thicker than one's finger, more or less muricated (as well 

 as the rachis\ densely paleaceous with large whitish scales 1-1^ in. 1. ; fr. 

 bipinnate ; pinril. lanceolate, deeply pinnatifid, 6-8 in. 1., lanceolate, acuminate, 

 deeply pinnatifid ; lobes linear-oblong, acute, serrated, falcate, glabrous ; racMs 

 and costce slightly hairy ; sori generally covering the whole of the lobes ; invol. 

 very thin and membranaceous, at length forming a shallow cup, entire or more or 

 less torn at the margin. Hk. Sp. 1. p. 17. t. 9. A. C. bicrenata, Liebm. 



Hab. W. Indies, Brazil, Mexico. Guatemala ?, Salvin & Godwood (not at all muri- 

 cated). 



6. C. insignis, Eat. ; st. very paleaceous at the base with long, glossy, subulate 

 scales; fr. ample, coriaceous, glabrous, dark-green, glaucous beneath, all the 

 rachises and costce beneath muricated; prim, pinnce 3 ft. 1. ; second, ones 7-8 

 in. 1,, ^-f in. w., elongato-oblong, finely acuminated, sessile, pinnatifid nearly to 

 the costa ; lobes oblong-falcate, obtuse, quite entire, the margin slightly reflexed ; 

 sori copious ; invol. firm-membranaceous, cinnabar-brown, sub-pruinose (with a 

 glaucous tint), often breaking down into 4 subequal valves. Eat. in Fil. Wright , 

 et Fendl. p. 215. 



Hab. Jamaica, on St. Catharine's Peak ; elev. 5,000 ft., Wilson, n. 716. Cuba, 

 Wright, n. 1064. Mountain forests, Vera Cruz, Salvin. A fine species, quite free from 

 scales, except in the stoutest portion of the stipes I possess, where there are traces of 

 long subulate glossy dark-brown ones, free from hairs ; fronds glaucous beneath, and 

 with very peculiar involucres. 



7. C. Imrayana, Hk. ; st. and racMs pale or dark-brown, sparsely tuberculato- 

 asperous, beneath and on the costse and costules more or less copiously clothed 

 with ferruginous down and scurfy with small, laciniated, often bullate scales ; 

 fr. subcoriaceous, bipinnate ; pinnl. lanceolate, acuminate, serrate, deeply pin- 

 natifid ; lobes oblong or linear- subfalcate, generally nearly entire ; sori near the 

 costa ; invol. globose, membranaceous, fragile, breaking down very irregularly.

 ]3. submidata / main rachis with the scales deciduous. C. muricata W. ? 

 Griseb. ? 



Hab. West Indian Islands. Caracas. C. muricata is a species of Willdenow, founded 

 on the most unsatisfactory figure of Plumier. The generally copious scurfy scales on the 

 underside of the frond are mainly characteristic of our C. Imrayana. It appears to be a 

 high mountain species, gathered on the Blue Mountain Peak in Jamaica ; alt. 5,000ft. 



8. C. balanocarpa, Eat. ; " st. sparsely aculeated at the base and paleaceous 

 \vithbrown, narrow scales ; fr. glabrous, ample, bipinnate '"pinnae 12-15 in. 1., 

 2 in. br., oblong, acuminate ; pinnl. very numerous, 2-2^ in. 1., 2^ lines w., linear- 

 oblong, obtuse crenato-lobate in their lower half, with a distinct, rounded auricle 

 at the inferior base, the superior half of the pinnl., or less, entire ; sori, one cor- 

 responding to each lobe of the pinnl. ; invol. mamillseform, subcoriaceous with a 

 circular opening at the apex from which the capsules soon protrude. Eat. Fil. 

 Wright, et Fendl. p. 215. 



Hab. Cuba, C. Wright, n. 1063. A most distinct and well-marked species, admirably 

 distinguished by Mr. Eaton, I. c. 



9. C. cuspidata, Kze. ; "fr. bipinnate ; pinnl. alternate, subsessile, divergent, 

 oblong, cuspidate, 4|-6 in. 1. by 1| in. w., unequal at the base, deeply pinnatifid," 

 having beneath a few deciduous whitish scales ; lobes linear-falcate, the lower 

 fertile portion a little contracted, crenulate at the apex, and acute ; sori costal ; 

 invol. cinnamon-brown, firm, bursting very irregularly, "stipes hairy at the 

 base." Hk. Sp.l.p.lQ. t. 12. A. 



Hab. Peru, Poeppig.M.y fragments received from Dr. Kunze in many respects resem- 

 ble some of the forms of C. arborea; but the involucres are very different. 



10. C. divtrgens, Kze. ; base of the stout st. muricated, furfuraceo-tomentos"
