accords. The hail's, though sometimes copious and cobwebby, are gene-

5. C. Meiiziesii, Hook. ; fronds bipinnatc everywhere gla- 

 brous thick and coriaceous, ])inna) (large) oblong acuminate si- 

 nualo-pinuatifid, the segments or lobes not reaching half-VA'ay 

 to the rachis, rounded very obtuse obscurely crenate or ra- 

 ther entire, the sinuses rather wide bearing the fructifica- 

 tions at their base, involucres several on each side and at the 

 base of the sinus corneous opaque large, inner valve smaller 

 and narrower, rachis and simple or forked veins very promi- 

 nent and pale. (Tab. XXTX. C.) 



Hab. Oahu, Menzics, Lay and Collie in Beechey's Voy. — This is assu- 

 redly a very distinct plant, which had been no doubt confounded with one 

 or other of the described Sandwich Island Cibotia. The fronds are the 

 thickest and most coriaceous of all the species, and the pinnsc the largest 

 and broadest, sinuato-pinnatilid, the sori at the base of the sinus running 

 partially up the segments or lobes, and the costa and veins pale and 

 singularly thick and prominent, while the involucres are the largest of the 

 genus and very horny. 



6. C. Schiedei, Schlecht. et Cham. ; arborescent, fronds 

 bipinnate, pinnules (small) lanceolate finely acuminate pin- 

 natifid f of the way down with copious long fulvous hairs es- 

 pecially on the costa, segments ovate acute slightly falcate 

 somewhat glaucous beneath serrated, involucres copious small 

 8 — 10 on each segment coriaceous tawny transversely oblong 

 the valves nearly equal convex, inner one a liltle smaller, ra- 

 chis subarachnoid with woolly deciduous hairs, veins simple 

 or forked. (Tab. XXX. A.) — Cham. Sf Schlecht. in lAniKBa^

Hab. Hacienda de la Laguua, Mexico, Schiede and Deppc. Xalapa, 

 (,'alcotti, n. 6458. Guatemala, G. U. Skinner, Esq. — Schlechtendal and 

 Chamisso justly observe that this is a more elegant Fern than any of its 

 congeners. Caudex 10 — 15 feet high, (Galeotti). The pinna are small, 

 3 — 4 inches long, much acuminated into a narrow point, slightly glaucous 

 beneath and there clothed with copious long tawny hairs. It is indeed ve- 

 ry different from any other species ; and has the segments so small that the 

 involucres meet in the centre of them, and nearly cover and conceal the 

 whole surface.

 Dicksonia, Kaiilf. Presl. 

 Sori marginal at, and towards, the apices of the segments, 

 on short teeth, pointing forwards, exserted, always from the 

 a]3e'x of a vein. Involucre shallow and pateriform or cup- 

 shaped and compressed, membranaceous, of a different tex- 

 ture from the fronds (not coriaceous nor herbaceous), mouth 

 entire. Receptacle elevated, but short and wholly included
