THE FERN WORLD OF AUSTRALIA. 7^> 
late, acuminate, equally or obliqifely taipering iniio a shoi^t pctioluTe- 
three to six inches lohg, four to eight lines broad, often denticulate; 
smooth and shining but not thick. Veins numerous,, parallel, three- 
quarters to one line apart. Pinu'ee of the fertile frond almost 
filiform, also numerous. One of the most beautiful of climbing 
ferns, found at Rockingham Bay and Trinity Bay, where some of 
the large scrub trees have their trunks completely clothed with its 
long feathery drooping fronds. 
A. repandum, Blume. Rhizome creeping. Fronds one to three' 
feet long, the stipes of the fertile froiids generally the longest: 
Sterile fronds firm, membranous, ovate-oblong, acuminate, pinnate. 
Pinnaa four to six inches long, about one inch bi*oad, more or less 
petiolulate, lanceolate, pinnati fid about half way down to the costule 
with ovate-rotundate lobes, with rather broad sinuses bluntly serrated 
at the margin and generally bearing subulate setse in the sinuses ; 
terminal pmnae sessile, the base decurrent down the rhaehis. Fertile- 
fronds with smaller irregularly lobed pinnae, the setiB of sinuses' 
more prominent. Veins forming a series of elongated costal areoles, 
other veins forming a feW more squai'e-shaped and smaller areoles, 
the outer ones free to the margin. Queensland, Rockingham Bay, 
Daintree River and Cape York Peninsula. 
A neglectum, Bail. Rhizomie creeping, scaly, dark-colored, 
hard. Fronds of two kinds, like a Lomaria, one to three feet high, 
lanceolate in outline, deeply pinnatifid, stipes in the fertile frond 
more than half its length and bordered by a narrow wing, segments, 
linear, jointed by the narrow wing of rhaehis, but not decurrent, 
one aind a half to three' inches long. Stipes of sterile frond half 
the length of frond, boi'dered by a toothed or lobed Wing to the 
base. Segments lanceolate, coarsely serrated, teeth almost 
aculeate, and some again serrate, three to six inches long, half to 
three-quarters inch broad, joihed at the base by the Wing of rhachis' 
which is about half an inch broad. Veins as in A. repandum. I met 
with this beautiful species in a close gully of the Trinity Bay' 
Ranges, in May of 1877. Df. Prentice tells me that Mr. Hill 
brought the same species from the North of Queensland several 
years before, and that he saw while on a visit to England, a specimen 
of the same, labelled in J. Smith's herbarium as A. repandum, from 
which it differs Widely according to diagnosis given in Hooker's 
Species Filicum, with which our form of A. repandum perfectly . 
agrees. 
A. attfeum, Linn. Golden swanip fe^n. Rhizome, stout, ei^eet, 
forming immense masses in the salt swamps. Fronds in young 
plants often consisting of the terminal pinna only ; adult fronds 
from two to six feet high, pinnate, glabrous, the rhachis firni and 
smooth. Pinnae distant, the lower ones petiolulate, the upper often 
decurrent, coriaceous, entire oblong, thtee to four inches long, three- 
quarter to one inch broad, the fertile ones rather smaller and a few 
only at the upper part of the frond. Veins oblique, very fine and 
numerous, copiously reticulate ; the whole plant having a yellowish
