THE FERN WORLD OF AUSTRALIA. 
broad, smaller in the more compound specimens. Veins forked, free 
or very rarely here and there anastomosing. Sori continuous round 
the margin or interrupted. On rocks of most "of the ranges of 
Northern Queensland. 
L. lobata, Poir. Rhizome creeping. Fronds six to twelve 
inches high, simply pinnate or bipinnate with few pinnate pinn^ at 
the base, much resembling the less-branched forms of L. flabellulata 
but the fertile pinnse often more than half inch broad,' and the 
veinlets frequently anastomosing. Northern Queensland damp 
rocks. 
L. triehomanoides, Dryand. Rhizome closely knotted, or very 
shortly creeping. Fronds rather rigid six to twelve inches high, 
bipinnate. Primary pinnse almost opposite, usually half inch long, 
pinnules obovate or oblong- cuneate, equilateral, two to three lines 
long, the upper ones confluent, all rounded and entire at the end 
with a continuous sorus, or notched with an interrupted sorus and 
indusium. Veinlets forked, not anastomosing. Found near Mac- 
quarrie Harbour, Tasmania, and perhaps at a few places in N. S. 
Wales, but uncertain. 
L. micropliylla, Sw. Rhizome closely knotted or shortly creeping 
and densely clothed with glossy brown scales. Fronds six to 
eighteen inches high, bi-tripinnate, elongated or oblong-lanceolate 
in outline, stipites hairy at the base, rhachis flexuose. Primary 
pinnse distant, barren pinnules varying from ovate to lanceolate, 
toothed or lobed ; fertile ones obovate, cuneate or flabellate, equi- 
lateral, one to two or more lines broad, undivided with a continuous 
sorus, or notched or lobed with the sori interrupted. In Queensland 
near Brisbane, common along Stony Creek, also on hill-sides under 
a good shade. Also Port Jackson, Clarence River and New Eng- 
land, N. S. Wales. 
L. incisa, Prentice. Rhizome long creeping, of a bright golden 
color, sparsely clothed with hair-like white scales, often forked, fronds 
from its whole length, often close four or six to the inch. Fronds 
from a few inches to two feet long, pinnate, pinna3 occupying nearly 
the whole length of frond, stipes and rhachis, tetragonous. Pinn^ 
entire flabelliform, bi-trifid or divided into three or more bifid 
cuneate pinnules. Sori large, with a deep, entire or notched indusium. 
Queensland : usually found on damp sandy soil under the shade of 
small trees, Eight-mile Plains, Brisbane River, &c. 
L. Fraseri, Hook. Rhizome long creeping wiry. Fronds pinnate 
six to eighteen inches high, stipites short. Pinnae membranous, 
distant ; from ovate to lanceolate, equilateral, obtuse, truncate or 
cordate at the base and shortly petiolate, quarter to one inch long, 
the upper ones smaller and somewhat rhomboidal, the barren ones 
often denticulate, the veinlets frequently anastomosing. Sori 
marginal continuous or slightly interrupted. Common in swamps 
at the Glasshouse Mountains, Moreton Bay, Eight-mile Plains 
and other parts of Southern Queensland. 
L. ensifolia, Sw. Rhizome creeping. Fronds simply pinnate
