THE FERN WORLD OF AUSTRALIA.

A. furcatum, Thunb. Rhizome thick, dark brown, scaly-hairy. 
Fronds six to eighteen inches high, pinnate or bi-pinnate, slightly 
scaly-hairy. Pinnee lanceolate, about one and a half or two inches 
long, deeply pinnatifid or pinnate ; segments varying from oblong- 
cuneate, toothed and confluent to linear-lanceolate, distinct and 
deeply two to four lobed, the segments or lobes all coriaceous, 
denticulate at the end, striate with few diverging veins. Sori few, 
large. Grose River, N. S Wales ; Grampians, . Darlot's Creek, 
Victoria ; also King George's Sound, Western Australia. 
A. laserpitiifolium, Lam. Rhizome samewhat erect or shortly 
horizontal, clothed with satiny ferruginous scales at the top. 
Fronds one to four feet high, stipes dark, glossy, glabrous, three 
or fovir times pinnate. Larger primary pinnae six to twelve inches 
long, with numerous secondary pinnse of one to three inches, again 
pinnate or the upper ones shorter and pinnatifid only, the primary 
as well as the secondary pinnee tapering into a pinnatifid point. 
Ultimate pinnules or segments obovate or oblong-cuneate, toothed, 
prominently striate with diverging veins, mostly three to. four lines 
long. Sori several on each segment, linear, usually rather small, 
often opposite to each other, and opening face to face. Found in 
the dense scrubs of tropical Queensland growing on rocks, old 
logs, &c. 
Section II. — Darea. Sori oblong or linear, on a vein proceed- 
ing from the mid rib in the pinnse as in Euasplenium, but on a 
branch parellel to the margin of its teeth or lobes with the indusium 
opening towards the margin so as to appear marginal. 
A. bulbiferum, Forst. Rhizome thick, scaly, erect. Fronds one 
to two feet long, glabrous or stipes and rhachis scaly, pinnate or 
bi-pinnate, often proliferous. Primary pinnse numerous, usually 
three to four inches long. Pinnules lanceolate, mostly half to one 
inch long, pinnately toothed, lobed or divided, with a single veinlet 
to each lobe or tooth ; the whole frond as well as each pinna ending 
in a lanceolate, toothed or lobed point. Sori large, one to each lobe 
or tooth, affixed to the central vein, but the rather rigid prominent 
indusium thrown over towards the margin so as to make the sorus 
appear marginal. Found in the scrubs of N. S. Wales, Victoria, 
Tasmania, and at Mount Gambler, South Australia. 
A. flaccidum, Forst. Rhizome short and thick, often scaly. 
Fronds from one to two feet long in Australian form, often much 
longer in forms of other places, pale green glabrous, pinnate. 
Pinnse coriaceous, narrow, three to six inches long, the barren ones 
toothed, the fertile pinnately divided into linear lobes of two to six 
lines, each bearing a single rather large sorus attached to the central 
vein, but the conspicuous indusium thrown over to the upper side 
so as to appear marginal. Found on rocks, &c., in N. S. Wales, 
Victoria and Tasmania, 
A. pteridioides, Baker. Rhizome short thick. Fronds broadly 
ovate-lanceolate in outline, four to eight inches long, three to five 
inches broad, glabrous, coriaceous, pinnate. Pinnas broadly Ian-
