n4. C. canaliculata, W. ; unarmed or indistinctly tuln'rculate ; fr. glalirous, 

 bipiiinate ; prim, pinnce 8-18 in. 1., oblong, acuminate, bipinnate, piniiatifid at 

 tlie apex ; pinul. sessile, 1-1 j in. 1., oblong, suljacute, entire or serrated ; veins 

 copious, twice or thrice forked ; sori copious near the costa ; invol. at first globose, 

 then breaking down into 8-4 tolerably regular lobes ; st. and tiie stout nvA\i\rachis 

 brown or purple-black. — llk\ Sp. 1. p. 23. t. 11. B. — /3 latifolia ; larger, pitail. 

 broader.— >S/>. Fil. p. 2-i. t. 13. A. 



Hab. Mauritius and Bourl)on ; Madagascar, Newton. — It is possible tliat this may have 

 tripinnate fronds, but my numerous specimens are not large enough to indicate if it be so. 

 Tlie species is very distinct, but varies much in tlie size of the pinnules.

 serrulate, small bullate scales on the costules ])eneath ; sori copious, close to the

 lanceolate, short-acuminate, 2-8 in. 1., dark, livid green, paler beneath, minutely 

 chaffy at the costse ; lobes approximate, oblong, subacute, subfalcate, crenulato- 

 serrate ; sori close to the costa ; invol. membranaceous, ])ale or chestnut-brown, 

 fragile, soon breaking into very irregular lobes. — Hk. Sp. \. p. 25. Mett. in Miq.

Hab. Java. — This presents no very striking specific character. Mettenius, who gives 

 a very full description, I. c. , remarks, " Iiidusio conditione et consistentia ab speciebus 

 antecedentibus diversa; viz. C. Javanica, Korthalsii, hymenodes, Zollingeriana, orientalis, 

 and Sechdlarum.'^ 



37. C. javanica, Bl. ; " arboreous, unarmed ; fr. bipinnate, subcoriaceous ; 

 pinnl. lanceolate, acuminate, deeply pinnatifid, bullato-squamulose at the base of 

 the costa ; lobes linear-sul^falcate, obtuso-crenulate or entire, plane ; sori 2-5, 

 parallel to the costa ; second. 7-achis paleaceo-tomentose ; p'im. one asperuhms, 

 with minute bristles." — Bl. En. p. 245. Hk. Sp. l.p. 26. Mett. in Miq. Ann. Mus.

Hab. Java, Sumatra. — Mettenius describes the invohicres as rigidly membranaceous, 

 but breaking down into a nearly plane circular base : this is true in some of my authentic 

 specimens ; in others it breaks into unequallydobed cups. Notwithstanding the careful 

 descriptions of Dr. Mettenius of the Malayan species of Cyalhea, I fear we have yet much 

 to learn with regard to their limits. 



38. C. intcgra, J. Sm. ; unarmed ; fr. firm-membranaceous, brownish-green, 

 paler beneath, glabrous ; prim, pinnce ample, 1^ ft. 1. ; pinnl. sessile or petiolute,

 to the costa, broad-oblong, subfalcate, acute, serrated ; sori in 2 series, intermediate 

 between the costule and margin ; invol. pale-membranaceous, breaking down into 

 a persistent, lobed cup. — Hk. Sp. l.p.2Q; and in Ic. PL 7. t. 638. Mett. in Miq.,

 glossy ; fr. ample, glabrous, subcoriaceous, bipinnate ; prim, pinnce distant, peti-
