72. Fracinus denticulata? Heer. A fragment only, the upper part of a small 
oblong oval leaf, with borders slightly denticulate, the lateral nerves mostly 
craspedodrome, entering the teeth. By the form, the size of the leaf, and 
the nervation, the fragment is similar to that described by Heer, Arct. FI, 
II. p. 118, Plate XLVII. fig. 2. The identity is not positively ascertained. 
1 specimen. 
Sapotacee. 
73. Styrax ambra, Ung. Leaves membranous, broadly ovate, round-trun- 
cate at base and abruptly attenuated to the petiole, entire, pinnately nerved ; 
secondary nerves curved, following the borders, camptodrome, branching at the 
apexes, the lower pair following the borders, joined to the medial nerve at a 
short distance from the base; nervilles transverse, obhque, continuous. 
One of the leaves referred to this species is preserved whole, except the apex, 
and is conformed in all its characters like that figured by Unger, Sillog., III. 
p- 34, Plate XXIV. figs. 19, 20. 2 specimens. 
74. Styrax Laramiense, sp. nov- Leaf subcoriaceous, smooth on the surface, 
oval, very entire, equally narrowed in rounding downward from the middle to 
a short petiole and upward to the point (broken), pinnately nerved; medial 
nerve straight, narrow; secondaries at an acute angle of divergence, a little 
curved in passing to the borders, which they follow in areoles. 
One leaf only 53 cm. long, 4 cm. broad; the lateral nerves at an angle of 
divergence of 30°. It is related to S. officinale, Linn. 1 specimen.
