Kacbis and stipes covered with ferruginous hairs, so as to
be quite rough.
L en g th of frond from twelve inches to two feet; colour-
full g reen, and having a glossy appearance.
Sori linear and continuous, solitary, generally only occupying
a portion of the superior margin.
Sir W. J . Hooker remarks th a t it is a more ten d e r and
membranaceous plant than A d ia n tum villostim, with smaller,
more copious, and much denser pinnules, g radually tapering
to a narrow point.
My thanks are due to D r. J . D. Hooker, of the Royal
G aidens, Kew, and to M. Schott, of the Imp e ria l Gardens of
Schonbriinn, near Vienna, for plants and fronds of this species.
I am not aware th a t it is in any of the N u rse rym en ’s
Catalogues.
The illustration is from a plant in my own collection.
