Sori circular, uniserial, and irregularly scattered.
The fronds articulated with the stipes, and at some distance
from the rhizoma.
L ength of frond twelve to fourteen inches; colour brilliant
green.
j\Ir. Sim, in his new Catalogue, enumerates four species:—
Neriiformis. Cavanilles. From Hirtella . Miquel.
Natal. Nodosa. Presl.
Articulata. Presl.
As some doubt yet hangs over these species, it has been
thought the wiser plan to figure the two species according to
Smith, leaving the fu rth e r discussion and enumeration to the
A p pendix, in order th a t the Author may have an opportunity
of seeing the living plants.
Lor fronds of this F e rn my thanks are due to Mr. J . Smith,
of the Royal Gardens, Kew, and to Mr. Joseph Henderson, of
"Wentworth.
I t is in the Catalogues of Messrs. Veitch, of Chelsea; Sim,
of Foot’s Cray; A. Henderson, of Pine-apple P la c e ; and
Booth, of Hamburg.
The illustration is from Mr. Smith’s frond.
