Nothochlaena. | FILICES. 67 
sparingly villous or hairy above, beneath densely covered with long linear- 
subulate ferruginous scales, 2-pinnate. Primary pinnae stipitate, opposite 
or nearly so, the lower remote, 4-2 in. long, ovate-deltoid, pinnate at the 
base, pinnatifid above. Pinnules few, seldom more than 2-3 pairs, ovate- 
oblong, obtuse, the lowest pinnatifid at the base ; margins recurved, Sori 
forming a continuous line round the margin.—Hook. Ic. Plant. (1854)

Often confused with Cheilanthes Sieberi, of which it has the habit and general 
appearance; but a smaller plant, with the frond conspicuously shaggy and scaly 
beneath. 
24, CHEILANTHES Swartz. 
Rhizome short and tufted, or long and creeping. Fronds usually 
small, erect, 2-3-pinnate; texture subcoriaceous. Veins free, forked, 
incomplete vertical ring. 
A genus of about 80 species, found in most tropical and temperate regions. It 
is only separated from Nothochlaena by the modified tooth or lobule of the frond 
reflexed over the sorus, a character which is sometimes so obscure that it is difficult 
to separate the two genera. The two New Zealand species are both widely distributed.

1. C. tenuifolia Swartz Syn. Fil. (1806) 129, 332.— Rhizome very 
short, suberect, clothed with silky scales. Stipes 3-9in. long, tuited, 
wiry, erect, dark red-brown, smooth and polished, glabrous or slightly 
scaly when young. Fronds 4-10in. long, 2-4in. broad, deltoid or ovate- 
deltoid, submembranous, yellowish-green, 3-pinnatifid; rhachis smooth, 
polished, glabrous or nearly so. Primary pinnae 6-12 on each side, 
opposite or nearly so, ascending or spreading; the lowest pair some- 
times 24in. long, deltoid; the upper smaller and narrower. Pinnules 
oblong or elliptic-oblong, deeply pinnatifid ; ultimate segments entire or 
irregularly lobed or crenate ; surfaces glabrous. Sori on the margins of 
the lobes, generally confluent and continuous all round the edge of the 
pinnules. Indusium narrow, elongated, usually crenate or denticulated, 
often transversely wrinkled.—Hook. Sp. Fil. ii (1858) 82, t. 87¢; Hook.
