length of the frond, which is pinnate, the innnæ being oblong-
obtuse, somewhat wedge-shaped at the base, and blunt at the
apex. The margin deeply and bluntly serrated, rachis winged
throughout, the stipes scaly.
The sori copious, eventually becoming confluent.
Terminal fronds attached to a somewhat creeping rhizoma.
A cool greenhouse evergreen species, not difficult to cultivate.
A native of Van Diemen’s Land, New Holland, and New
Zealand. The A . lucidum Avas also introduced from the latter
country.
This Fern was received at the Royal Gardens, Kew, in the
year 1843, from the IMessrs. Osborn.
The A . ohtusatum of Labillardiere is a different species; it
is the A . sarmentosuni of WilldencAv.
My thanks are due to Mr. Henderson, of Wentworth, for a
plant and fructified fronds of A . ohtusatum.
It is in the Fern Catalogue of Messrs. Eollisson, of Tooting;
and that of A. Henderson and Co., Pine-apple Place.
The illustration is from a frond forAvarded by Mr. Henderson,
of IVentworth.
