FERN. 
Plate XX., Figs. 14 and 14a. 
Lamina about 1 inch long, \ inch wide, with oblique base and irregularly 
dentate or serrate margins. Midrib clearly defined, lateral veins parallel but 
not close together, making an angle of about 70° with the midrib, and running 
out to the sinuses of the margin. Intermediate venation apparently finely 
reticulate. 
The figure is taken from Specimen No. 40, Fig. 14a, showing a portion highly 
magnified. 
There are some other leaves preserved, the affinities of which are uncertain^ 
but as they are interesting, they have been figured. They are as follows :— 
Leaf 1J inches long, f inch wide, slightly curved, cordate at base, apex 
obtuse. Midrib well defined. Lateral veins, three or four only on each side, 
curved and much inclined to the midrib ; tertiary venation reticulate, the veins 
showing as lines running almost at right angles to the midrib, but falling away 
towards the margin. 
The leaf (Specimen No. 47) is figured in Plate XX., Fig. 15. 
Plate XX., Fig. 16, shows a leaf preserved in Specimen 52. It is about 
1J inches long, narrow ovate ; midrib thick, slightly undulate ; lateral veins 
few in number, curved ; intermediate venation, reticulate, with a tendency to 
arrangement at right angles to the midrib and lateral veins. There is some 
little resemblance to Mr. R. M. Johnston’s Phyllites Breaclalbanensis , Geol. Tas., 
Plate XLVII., Fig. 1, but the latter is longer, and has more lateral veins. A 
possible relationship which suggests itself is to Ficus. 
Plate XX., Fig. 17, shows a leaf preserved in Specimen 63. The leaf is 
linear obtuse, about 1 inch long, rugose, and with revolute margins. The 
midrib is w T ell marked; lateral veins almost transverse, branched before 
reaching the margin ; tertiary venation not conspicuous. The character of 
the leaf resembles that of Lasiopetalum rufum, R. Br. 
Plate XX., Fig. 18, shows a leaf preserved in Specimen 68. The leaf is 
ovate, cuneate attenuate at the base, 1J inches long, with smooth and revolute 
margins ; midrib well defined, lateral veins rather numerous, almost transverse, 
and apparently branching off into an irregular reticulation. Affinity to 
Myrsine suggests itself. 
Plate XX., Fig. 19, shows a forked and jointed branchlet, probably 
Casuarina. The specimen in which it is preserved is No. 70. 
Plate XX., Fig. 20, shows a fragment of a leaf preserved in Specimen 73. 
Its venation is peculiar ; its highly reticulate character resembles that of 
Mirbelia. 
(Specimens Nos. 284 to 318 inclusive.) 
The leaf remains are generally not well preserved, and are fragmentary. 
Where distinguishable they are mostly of Coprosmcephyllum. Some few speci¬ 
mens are in very good condition, notably No. 293, which is C. ovatum. 
The series is remarkable for containing little else than these fragments of 
Coprosmcephyllum leaves. Specimen 312, however, contains two fossils which 
are of special interest. One is a small leaf a little over J inch long, ovate, 
pointed at apex, with a distinct but short petiole at base. The venation is 
obscure, but seems to be reticulate. The affinity which suggests itself is to 
PultencBa. (See Plate XX., Fig. 21.)
