Hah. Ceylon, Dr. limeison, Mrs. Col. Walker. — The cau'lex of this is 

 ahoiit an inch in diameter, clothed with the dark hrown almost black bases 

 of the stipites of the old fronds, bearing a crown of elegant simple long wa- 

 vy fronds at the top. These have a stout costa. The veins are pinnated 

 and the veinlets bear the sori near the middle. Involucre globose or slight- 

 ly depressed, bursting very irregularly at the top, so as to become cup-shap- 

 ed with a very uneven margin, lleceptacle globose. Capsules on long stalks. 



2. C. Br/tiwnis, Wall.; fronds pinnate, pinna3 oblongo-lan- 

 ceolate acuminated with a long naiTow point sinuato-crenate 

 often serrated at the margin above. — IVall. Cat. n. 179. Hook.

Hal). Pulo Penang, Dr. Wallich, Lady Dalhomie. Malacca, Cuming, 

 n. 378. — This is a truly beautifid fern, but of which the caudex is unknown 

 to me, nor is it described in Dr. Wallich's MS. volumes of ferns, which I owe 

 to that gentleman's liberality. The stipes is one or two feet long ; the 

 frond 2 — 3 feet, alternately pinnated : pinna 6 — 8 inches long, between 

 membranous and coriaceous, obliquely truncated at the base and shortly 

 petiolate, tapering into a narrow acumen at the point. Sori copious, from 

 the middle of the forked veins or veinlets. Involucre of the same struc- 

 ture as the preceding, but in age more lacerated and lobed. Capsuh;s 

 stalked. 



3. C. Mexicana, Schlecht. ; unarmed, rachis and costa 

 above pubescenti-scabrous, fronds bipinno.te, pinnides lan- 

 ceolate acuHQinate pinnatifid glabrous, segments oblong 

 .slightly falcate rather obtuse serrated, sori confined to the 

 lower half of the segment, situated upon the veins which 

 are almost wholly simple or below the fork when divided 

 very rarely indeed at the forking, involucre exceedingly thin 

 and fragile almost resembling a thin coat of varnish when 

 perfect soon obliterated. — Scldecht. in Linncca. i\ v, p. 616.

Hab. River-sides, forests of Xalapa, Mexico, Schiede et Deppe. Gale- 

 otti. — This remarkable fern seems to have been found only at or near Xa- 

 lapa. It is remarkable in having the habit of the species of the following 

 sub-genus, but bearing the sori almost always on simple veins, or below 

 the forking in the rare instances of their being divided, sometimes but very
