“ Frond dichotomous, pinnate; racliis moderate in size, terete; pinna) 
remote, alternate, obovate-elongate, inciso-lobate ; nerves indistinct.” 
Obs . — I have placed this fossil with the genus Gleichenia especially 
on account of the dichotomy of the leaf and the form of the leaflets. The 
veins arc rather indistinct, the fossil being preserved only as an impression in a 
fine-grained, yellowish-greenish sandstone. It appears to me, from the faint 
venation, that the frond differs from Thinnfelclia odontopt oroides. 
Locality and Horizon. — On the specimen there was no other indication 
hut “ Wianamatta beds,” hut I would judge that it came from Clarke’s Hill, 
New South Wales (Mesozoic). 
Gleichenia lineata, Ten. Woods. 
Gleichenia lineata , Tenison Woods, loc. cit., 1S83, p. 130, PL 3, f. G ; PL 8, f. 2. 
Sp. Char. — “ Frond small, coriaceous, with a strong thick racliis, 
dichotomously divided, pinnate, hipinnate ; pinnules entire, linear, attached 
by almost the whole of the base, but slightly contracted at the lower portion, 
somewhat distant, not decurrent. Upper edge convex, lower slightly concave, 
but in a few pinnules divided into deep rounded lobes ;* apex acute, emerging 
from the racliis at an angle of about 35 degrees ; veins not prominent, costa 
not forking and quite persistent to the apex ; veins not very visible in any of 
the specimens, but apparently grouped and numerous, emerging at an acute 
angle and bifurcating. There appear to be two venules emerging at the very 
base of the pinnulae. Racliis conspicuously marked with a single deep dark 
median groove.” 
Obs. — Mr. Tenison Woods regards the species as closely related with 
Gleichenia Jlabellata, R. Br. 
Locality and Horizon.— At Rosewood Scrub, near Ipswich, Queens- 
land, preserved in a red ferruginous oxide in purple slate (Upper Mesozoic). 
Genus — MERIANOPTERIS, Heer, 1877. 
(Flora Fossilis Ilelvetise, p. 88.) 
Obs. — This genus was originally established by Prof. Ileer, to include 
two fossil ferns from the Mesozoic rocks of Switzerland. I have described 
one species from the Middle Gondwana horizon, Raniganj Group, in India, 
* “ But this may be a monstrosity, as it is seen on a few pinn* of only one specimen.” (Note by Mr. 
Tenison Woods.)
