THE FERN WORLD OF AUSTRALIA. 
71 
forming a continuous line about one line broad. Found near 
Mount Olgar, Central Australia. 
G. Muelleri, Hook. Rhizome scaly, shortly creeping. Fronds 
six to twelve inches long, simply pinnate, the rhachis scaly. 
Pinnae in distant pairs, ovate or oblong, obtuse, entire, half to one 
inch long, thick, sprinkled above and densely covered underneath 
with eiliate scales. The early fronds simple cordate. Sori nearly 
buried under the scales, very numerous, mostly short, transverse 
but crQwded in an apparently continuous line round the margin, 
usually about a line and a half broad. Queensland, Rockingham 
Bay, Cleveland Bay, Rockhampton and Gilbert River. 
Gr. rutaefolia, R. Br. Blanket fern. Rhizome a short knot. 
Fronds tufted, three to six inches long, pinnate. Pinnae obliquely 
obovate or almost fan-shaped, three to six lines long and broad, 
toothed, lobed, or again somewhat pinnate, contracted into a short 
petiolule, sprinkled above and more densely covered underneath 
with brown scaly hairs occasionally glandular. Veins forked and 
radiating. tSori linear, mostly about the middle of the pinna3, 
sometimes almost covering the surface. Very widely distributed 
throughout the whole of the Australian Colonies and Tasmania. 
G. leptopliylla, Swartz. Jersey fern. Rhizome a short tult. 
Fronds delicate, under six inches higli and frequently only two or 
three inches, the outer ones short with few broadly obovate or fan- 
shaped segments, often barren, the other erect with a slender black 
rhachis twice pinnate : segments numerous, oblong or cuneate, 
two to three lines long, more or less deeply lobed, with usually a 
single oblong sorus on each lobe, often covering the whole suriace. 
Port Stephens, N. S. Wales; Yarra and Lodden River Vale near 
Sale, Gippsland, in Victoria ; Spring Bay, near the Tamar, Tas- 
mania ; Barossa and Lofty Ranges, South Australia ; and also 
in Western Australia. 
G. pinnata, F. v. M. Rhizome shortly horizontal. Fronds 
one to two feet high, simply pinnate, glabrous. Pinnae three to 
eleven or reduced to a single terminal one, lanceolate, four to ten 
inches long, half to one inch broad, contracted at the base into a 
short petiolule, entire, the prominent costule and rhachis smooth 
and shining. Veins diverging from the costule, forked and 
anastomosing; Sori linear or narrow-oblong, very unequal and 
irregularly scattered. Ranges of Rockingham and Trinity Bays, 
Queensland. 
G. ampla, F. v. M. Rhizome rather thin for the large size of 
fronds, scaly, creeping like Polypodium scandens up the trunks of 
trees. Fronds one to three feet long, from simple and entire 
to deeply pinnatifid, with segments lanceolate and from three to 
nine inches long, three-quarters to two inches broad, membranous, 
entire, decurrent and connected by a broad wing to the rhachis, 
the wing gradually tapering below the lowest pair but continued 
almost to the base of the stipes. Veins proceeding from the mid- 
rib immediately forked, one branch bearing a straight linear sorus
