The venation is also not unlike that of Taberncemoutana, of the natural 
order Apocynacece. It is, therefore, on the whole advisable to place the leaf 
as stated, and not to multiply genera. 
MONOCHLAMYDEiE. 
Montmiace^e. 
Atherosperma Berwickense, sp. nov. 
Plate VII., Figs. 1, 2, and 3. 
Leaf from 1\ to If inches or longer, rhomboidal in shape, more or less 
oblique, especially at the base, the margins bluntly dentate. Midrib strongly 
marked, curved; lateral or secondary veins conspicuous, running out towards 
the teeth, nearly straight, about 40° to the midrib. Tertiary venation reti¬ 
culate, with a tendency to an arrangement more or less at right angles to 
the secondary veins, not very conspicuous, being apparently immersed in a 
leaf of somewhat leathery consistence. 
The above description is taken from the leaves shown in specimens 99, 
109, and 244, the two former being basal fragments only, the latter a com¬ 
plete leaf. They seem to approach nearer to Atherosperma or Doryphora 
in character than to any other genus or group. Atherosperma leaves are not 
infrequently curved, though not in so pronounced a manner as some of the 
fossil leaves show, but the character exists. The arrangement of the lateral 
veins and the teeth of the margin are perhaps more like what occur in 
Doryphora sassafras , Endl., than is generally the case with Atherosperma 
moschata , Lab. I have, however, observed some leaves of the latter species 
which quite meet the case. There is a slight resemblance to the leaves of 
Orites Milligani , Meissner, a Tasmanian protead, but the teeth are acute 
and further apart than in the fossil leaves here. 
The leaf contained in specimen No. 253 has some points in common with 
the above, but the serrations of the margin are finer, and the characters 
generally are more those of Fagus. I have placed it under Ettingshausen’s 
Fagus Muelleri from Vegetable Creek (Cont. Tert. FI. Aust., PI. X., 
Figs. 3-7). 
Mollinedia helicioides, sp. nov. 
Plate VI., Fig. 5. 
Leaf probably 4 J or 5 inches in length, ovate or ovate lanceolate, 2 inches 
wide, margin slightly sinuate, and with sharp points or teeth about a line 
long. Midrib stout, lateral or secondary veins starting at yarious angles from 
nearly 90° to about 45° with the midrib, curving round before reaching the 
margin and ultimately joining the next above. Tertiary veins forming a 
coarse reticulation, but arranged chiefly when near the midrib at right 
angles to it, and further out in the lateral veins at right angles to them. 
Final reticulation not so conspicuous. Texture apparently coriaceous. 
There can, I think, be little doubt of the relationship of the leaf in ques¬ 
tion, which is preserved in specimen 242. It has the general character of 
the Monimiacece , and approaches more nearly to some existing species of 
Mollinedia than to those of any other genus. It is evidently allied to, 
though specifically quite distinct from, Mollinedia Muelleri , described by 
me in my notes on the Pitfield specimens (see No. 5).* The small sharp 
teeth form a character which is shared with the existing M. Huegeliana , 
Tulasne, and also Helicia ferruginea , F.v.M., and I have made use of its 
resemblance to the last-named genus to make the specific name.
