ing to a point and decurrent on the short stipes, often ver j numerous 
forming large tufts on the stems of trees. Veins transverse simple 
or forked, mostly about one line apart, not connected within the 
margin. Sori linear, not reaching either the margin or costa. 
Rockingham Bay, Trinity Bay, Bellenden Ker Ranges and Cape 
York Peninsula, Queensland. 
A. attenuatum, R. Br. Rhizome a short knot or shortly creep- 
ing. Fronds linear-lanceolate bordered by distant short teeth,' six 
to eighteen inches long, half to one and a half inch broad, nearly 
entire for the greater part of their length and tapering into a long 
point, frequently proliferous at the end, usually broken up in the 
lower part into a few obovate or oblong laterally adnate segments, 
the mid-rib scaly-hairy underneath as well as the stipes. Yeins 
very oblique, simple or forked. Sori variable in length, often 
reaching the mid-rib, rarely the margin. Abundant on damp rocks 
in southern Queensland, and throughout N. S. Wales. 
Var. multilobum, F. v. M. Fronds similar in size, or rather 
broader, but broken up nearly the whole length into rounded, ovate, 
serrated segments, the elongated apex proliferous. Found in the 
Logan district, Queensland : and Richmond River in N. 8. Wales. 
Var.* integrum. Rhizome creeping, a few inches long, slender. 
Fronds tufted, six to sixteen inches long, half-inch or less broad, 
oblong, or tapering into an acuminated, proliferous, apex, rounded or 
decurrent at the base upon the slender hairy stipes. Found on 
rocks and wet banks at Maroochie, Queensland. 
• A. Trichomanes, Linn ; European Maiden-hair, spleenwort. 
A small tufted fern. Fronds two to six inches high, simply pinnate, 
the rhachis slender, usually black. Pinnae numerous, obovate, 
orbicular, or broadly oblong, nearly equal in size, those of the 
middle of the frond the largest, two to three or rarely four lines 
long, more or less toothed. Veins forked, radiating from the mid- 
rib. Sori several on each pinnae, oblong-linear and distinct when 
young, uniting in a circular mass when old. Port Jackson and Blue 
Mountains, in N. S. Wales ; many places in Victoria and Tasmania. 
A. fiabellifolium, Cav. Fan-shaped spleenwort. Rhizome a 
small knot. I^ronds tufted, weak straggling, slender, often proli- 
ferous at the apex, six inches to near one and a half feet long, 
simply pinnate. Pinnae shortly petiolulate, obliquely obovate, 
orbicular or fan-shaped, toothed, the larger ones sometimes three- 
lobed, two to three lines broad in the small Queensland plants, 
but the more southern forms often over half-inch. Veins few, 
forked, pinnately diverging from a short mid-rib often divided at 
the base into three nearly equal branches. Sori several on each 
pinn^, linear when young, often confluent when old. On rocks 
Enoggera Creek, near Brisbane, and Dalrymple Creek, Southern 
Queensland ; very common in N. S. Wales, Victoria and Tasmania ; 
Mount Lofty Range, Adelaide, South Australia, and also at a few 
places in Western Australia. 
A. paleaceum, R. Br. Rhizome short, tufted. Fronds decum-
