Hab. Juan Fernandez, llertero.—A solitary and very rare Fern. T remove this genus
to the Tribe Cyatliecc, to which, I think, it has a closer affinity than to Dicksoniccc.
Gen. 4. Ctatiiea, Sm.
Sori on a vein, or in the axil of the forking- of a vein. Recept. elevated, glohose,
or elongated. Inm l. globose, inferior, covering the whole sorus, afterwards breaking
at tire summit and forming a more or less persistent cup, even or irregular at
tlie margin.—Arborescent, tropical or subtropical. St. often aculcated. Fronds
simple or pinnate, or decompoundly pinnate. T ab. I. f. 4.

Hab. Wooded mountains, Ceylon, rare ; most abundant in the Singhe-rajali Forest.—
If not among the smallest, certainly among the most elegant and graceful of cyatheaceous
plants, and the only one we know with quite simple fronds. A native only of Ceylon.

black, mui-icated a t tlie base and subpaleaceous ; f r . coi-iaceo-membranaceous,
2-3 ft. 1., 4-6 in. w., elongato-lanceolate, acuminate, pinnate, jiinnatifid at the ap ex ;
J from a broad base auricled on both sides, suhlinear-lanceolate, acuminate,
* The three preceding species are readily enough distinguished by the undivided or
simply pinnated structure of the frond, combined with other peculiarities : but it is far
otherwise with those which follow, whose fronds are more compoundly divided, which
present a much greater similarity one with another, and of which, on account of their
frequently gigantic size, we rarely receive other than mere fragments, telling nothing
of their arborescent trunks or candices, and rarely of their stipites. which often present
useful characters. I am unable to offer any better sections or subdivisions than according
to the countries they inliabit.

I have again examined with great care the two states of this plant, and am only the
more confirmed in my opinion that they constitute but one species.
