ap BULLETIN OF THE 
midrib, representing, in shape at least, the figure of that species in Saporta, 
Sezanne Fl., Plate XI. fig. 2. The sandstone is coarse and hard, and no trace 
of areolation is distinguishable. 1 specimen. 
79. Cissus parrotecefolia, Lx. 6 specimens. 
80. Cissus lobato-crenata, Lx, 1 specimen. 
81. Cissus corylifolia, sp. nov. Leaves thickish, ovate, blunt at apex, simply 
or doubly short dentate, strongly pinnately nerved; lateral nerves at an acute 
angle of divergence, close, parallel, scarcely curved in passing to the borders, 
the lowest much branched on the under side, the upper ones branching near 
their ends, craspedodrome ; nervilles at right angles to the nerves, simple or 
branched in the middle, deeply impressed. 
The leaves, finely preserved, vary in length from 6 to 9$ cm. and from 4 to 
74 cm. in width, being broadest a little below the middle. They have a degree 
of likeness to Purrotia pristina, Ett., as figured in Fl. v. Bilin., Plate XX XIX. 
fig. 23. 3 specimens. 
82. Cissus duplicato-serrata, sp. nov. Leaves of various size, subcoriaceous, 
ovate, taper-pointed, rounded at. base, palmately three, more generally five 
nerved; primary lateral nerves diverging from the midrib at acute angles, 
scarcely curving or not at all, entering the teeth which are prolonged into short 
lobes at a distance below the apexes, much branched outside; borders doubly 
irregularly dentate, the teeth pointed; all the nerves and their divisions dis- 
tinctly craspedodrome. 
The leaves are referable to Cissus, though they have a degree of affinity with 
some varieties of Populus Nebruscensis. They differ essentially by the primary 
lateral nerves not incurved, much branched, all the divisions, craspedodrome, 
the teeth acute, the substance of the leaves thick. 7 specimens. 
83. Cissus spectabilis, Heer, Fl. Schakal., p. 45, Plate III. fig. 3b. Leaves 
oblong-ovate, subcordate-emarginate at base, unequally dentate on the borders, 
very entire at and toward the base; lateral nerves branching. 
The above description is that of Heer, which fully agrees with the characters 
of the leaf which I refer to the species. The leaf is merely smaller; the teeth 
though unequal are not distinct, but mere crenulations, the same as seen in the 
figure of Heer. 1 specimen. 
84. Vitis, species undeterminable. 1 specimen. 
Hamamelidee. 
85. Parrotiu fagifolia, Ett. Leaf broadly oval, irregularly undulate on the 
borders; lateral nerves simple, alternate, distant, oblique, running straight to 
the borders as in a leaf of Fagus, which it resembles. The leaf has the charac- 
ters of the species, as figured in Fl. v. Bilin., Plate XL. fig. 24, and is positively 
identified. 1 specimen. 
Cornez. 
86. Cornus Studert, Heer. 2 specimens.
