An extremely variable little Fern.—Rhizome creeping, scaly, and having pilose roots. Fronds pinnate or 
bi- rarely tri-pinnate, numerous, ovate or linear-oblong, rather tufted, erect, 2-18 inches high. Stipes scaly at the 
base, and rachis slender, stiff, trigonous, polished. Pinne rather distant; in var. Lessoni simple, oblong-lanceolate, 
with a cuneate base, blunt, lobed, bearing sori on the lobes, more often pinnatifid, with cuneate lobes, very fre- 
quently bi- and even tri-pinnate. Pinnules always broadly cuneate, rounded in front, with a deep, continuous, intra- 
marginal sorus. The pinnules vary from 4-4 inch long; the larger are lobed, and bear a sorus on each lobe.

Beautiful terrestrial Ferns, natives chiefly of the tropies, but of which one species is found in Europe, and 
several occur in Australia, Tasmania, and New Zealand. —Rhizome creeping. Stipes generally black, often polished. 
Fronds bi-tripinnate in the Tasmanian species, with stipitate, broadly cuneate pinnules. Sori marginal, short, or 
linear and continuous. —Zmvolucre formed of the reflexed, often kidney-shaped edge of the frond, opening inwards, 
its surface veined, the veins continuous with those of the pinnules. (Name from adıayros, in allusion to the dry 
texture of the fronds.)

Has. Pasture-land, behind rocks and logs of wood; also in rocky places, freguent.— (e. v.) 
Disrris. Throughout Australia, New Zealand, and many tropical countries. (Cultivated in England.) 
A. assimile was regarded as a distinct species from A. Aithiopicum, till the author of the * Species Filicum ’ 
pointed out its identity with that plant. It is found in all tropical countries, and throughout the south temperate 
hemisphere, but is hardly known in the north temperate.—Everywhere perfectly glabrous, flaccid, mnbynnons, 
pale-green or yellowish. sStipites tufted, slender, 4-10 inches long. Frond oblong, often elongated, rr 
pinnate; primary branches alternate, distant. Pinnules 4-1 inch broad, broadly cuneate, stipitate; upper margin 
rounded, deeply lobed. Sori few.  Involucres very large, pale, kidney-shaped, placed in notches of the pinnules. 
Rachis slender, flexuose; partial ones and stalks of the pinnules capillary.
