THE PERN WORLD OF AUSTRALIA.

plant is often found growing on the hillocks formed by grass or 
other plants in swamps ; from the Brisbane River to Rockingham 
Bay. It is most abundant on some of the damp hills off the Pioneer 
River, and is also met with in New England and N. S. Wales. 
Lomaria capensis. A strong coarse fern, often forming a 
trunk of several feet in height. Leaves long erect of two forms, 
pinnate leaflets of barren leaves, rough. Found from Eight- 
mile Plains, near Brisbane, to Rockingham Bay in Queensland ; 
common in swampy parts of N. S. Wales, Victoria, South 
Australia, (Mt. Lofty ranges) and also Tasmania. 
Blechnum serrulatum. Rootstock long creeping, often running 
lip under the loose bark of tea-tree ; leaves long on long stalks, 
pale colored, the upper part bearing harsh linear leaflets the edge 
of which finely toothed, seed patches near the mid-rib. Found 
through Queensland round to Port Darwin and also in N. S. 
Wales. 
Asplenium sylvaticum. A short erect scaly rootstock, leaves 
one or two feet long, pinnate. Damp places, Rockingham Bay. 
Asplenium maximum and Asplenium polypodioides are two 
strong growing ferns which at times form a trunk of several feet in 
height crowned at the summit, and some distance down their trunks 
with large spreading leaves six or more feet long, and two or more 
feet wide. Both are met with in the swamps of Northern Queens- 
land and the first in several parts of N. S. Wales. 
Aspidium unitum. Stem creeping beneath the surface ; leaves 
erect, the upper portion only with leaflets which are from two to 
six inches long ; one form of this plant is quite downy at times 
but scarcely persistently enough to form a good variety. The plant 
is common to all the swamps of Queensland, is found also in many 
parts of N. S. Wales, and also Western Australia. 
Acrostichum aureum. A tall fern of a yellowish hue, rootstock 
short thick ; leaves pinnate, often six feet high, many together, 
forming large clumps in salt marshes ; on young plants the leaves 
are very frequently simple, that is formed of a single leaflet. 
Found from Port Darwin along the coast and up the river so far as 
the tide reaches through Queensland to the rivers Clarence and 
Richmond in N. S. Wales. A remarkable feature with this fine 
plant is that it will succeed under cultivation without the aid of 
saline influence. 
Group VIII. — Tree Ferns. 
Todea barbara. This might have been placed equally well with 
swamp kinds but at times it may be seen with a trunk of even 
more than six feet in height and two feet in diameter, thus proving 
its right to rank with tree ferns. The leaves with which this stout 
trunk is crowned are twice pinnate, and often more than six feet 
long ; the seed patches are placed on the lower lobes of the second 
leaflets. Found in wet parts in many parts of Queensland, as
