938 FILICES. | Hymenophyllum. 
14. H. Malingii, Metten. ex Hook. and Bak. Syn. Fil. 66.— 
Forming small patches on the trunks and branches of trees. 
Rhizome slender, creeping, sparsely clothed with reddish - brown 
hairs. Fronds 2-8in. long, 4—14in. broad, narrow-oblong to. 
linear, erect or pendulous, opaque, rigid, reddish-brown or greyish- 
brown, everywhere most densely covered with stellate hairs mixed 
with very minute close-set clavate papille, 2-3-pinnatifid. Stipes 
1-3in. long, very slender, almost filiform, not winged, densely 
tomentose. Pinne close or distant, 4—%in. long, rarely more, the 
lower ones ovate-rhomboidal, the upper oblong, deeply pinnatifid ; 
secondary divisions cuneate or flabellate, deeply pinnatifidly cut. 
Ultimate segments very narrow-linear, obtuse, almost terete and 
coriaceous from the dense coating of tomentum, which entirely 
conceals the frond proper. Sori small, terminating the segments. 
Indusium hidden by the tomentum, orbicular, 2-valved rather more 
than half-way down ; valves denticulate at the apex.—Thoms. N.Z.

A most curious and remarkable little plant, confined to New Zealand. The 
peculiar indumentum of the frond is well worth careful examination. 
15. H. Cheesemanii, Bak. ex Hook. and Bak. Syn. Fil. (edit. 2) 
464.— Minute, forming cushions on the branches of trees, or creep- 
ing amongst mosses and hepatice. Rhizome branched, wide- 
creeping, smooth and wiry. Fronds very small, +~1 in. jong, simple 
or forked or digitately 3—5-fid, quite glabrous, dark-green, texture 
firm. Stipes very short, filiform, {-+in. long. Segments about 
75 in. broad, linear-oblong or ligulate, obtuse, with a single stout 
dark-coloured costa in each; margins not usually conspicuously 
thickened, strongly ciliate-dentate ; teeth ascending, dark-brown or 
black, sometimes caducous. Sori 1-3 to a frond, terminating the 
segments. Indusium slightly sunk in the frond at the base, 
orbicular-oblong, dark brownish-black, of a more compact texture 
than the frond, 2-valved nearly to the base; valves smooth, convex, 
quite entire, recurved in age.—Ic. Plant. t. 1132; Cheesem. im Trans.

and margins strongly thickened.—H. Armstrongii, Kirk in Trans. N.Z. Inst.
