"White-leaved Bristle Fern. 4. This is the first time that it has been 
met with in Australia, and probably the summit of Bellenden-Ker is 
its only Australian habitat. The fronds are glaucous on the under 
side, which is unusual in the genus.

H. tunbridgense, Var. exsertum, Bail. The Bristle-bearing 
Filmy Fern. 3. This fresh form differs in having a long bristle-like 
exserted receptacle ; the indusium also was longer than usual. The 
receptacle is also exserted in the Lord Howe's Island specimens of 
this fern but there the plant is of much coarser growth. 
TSL. tridiomanoides, n. sp. 4. Rhizome nearly or quite glabrous, 
filiform, creeping up the stems of trees in long strings, seldom if ever 
forming matted patches on old damp logs. Fronds narrow or broadly 
lanceolate in outline ; sometimes the apex is much elongated, 3 to 5 in. 
long including the slender stipes, which is generally less than an inch 
long ; the rhachis is very narrowly winged but not the stipes, bipinnate, 
the lower pinnules often somewhat flabelliform and more or less deeply 
divided, the upper pinnas of from few to a single lobe, all linear, 
obtuse, with entire edges. Sori supra-axillary, deeply sunk on one or 
more of the lobes. Indusium oblong, 1|- line long, the valves entire, 
obtuse, receptacle always protruding from 1 to more than 2 lines in 
length. 
Hab. : Summit of Bellenden-Kei*. The outline form of this, especially when 
the pinnae and pinnules are crowded, remind of H. polyanthos of New Zealand, but 
it does not stain paper, and has not the fragrance of that fern, besides the difference 
of indusium and receptacle, which latter gives to this new species the appearance of 
a Trichomanes. Indeed it might be placed in either Tricliomanes or Symeno- 
phijllum ; I place it in the latter because the whole of the exserted portion of the 
indusium consists of the 2 long obtuse lobes.

This handsome fern-tree we found to be in greater abundance than any otlier. 
In fact, it at times formed much of the scrub we had to cut our way through. 
A. CapensiS, J. Sm.; Hook. Spec. Filic. i. 36. "Wig Fern-tree. 3. 
Trunk erect, 12 feet high, reddish, slender, seldom exceeding a diameter 
of 2 in. Fronds 6 to 8 feet long, the base of the stipes for a few inches 
pressed to the stem and here bearing a hymenophylloid growth of a 
purplish or green and purple hue, thin as thread, and many times 
forked, giving a wigged-like appearance to the crown of the trunk ; 
stipes and rhachis more or less clothed with long, simple, hair-like 
scales ; centre pinnae about 2 feet long, lanceolate, acuminate ; 
secondary rhachis more or less covered with small fringed chaffy 
scales ; pinnule 2 to 4 in. long, the attenuated apex serrated, the lower 
half with a rounded auricle at times very prominent, upper half 
truncate and parallel with the secondary rhachis ; veins forked or at 
times simple ; sori much elevated, almost cylindrical, on the middle of 
the vein. 
Hab. : In a deep rocky gully at Palm Camp, elevation about 4,000 feet. Never 
before found in Australia, although, known from South Africa, Brazil, and Java.
