72. Fraxinus denticulata ? Heer. A fragment only, the upper part of a small 

 oblong oval leaf, with boixlers 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. Fl., 

 II. p. 118, Plate XLVII. fig. 2. The identity is not positively ascertained. 

 1 specimen. 



Sapotaceae. 



73. Styrax anthra, 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, oblique, 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 linger, SiUog., III. 

 p. 34, Plate XXIV. figs. 19, 20. 2 specimens. 



74. Styrax Laramiense, sp. nov. Leaf subcoriaceous, smooth on the surface, 

 ov.il, 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 5 J cm. long, 4 cm. broad; the lateral nerves at an angle of 

 divergence of 30°. It is related to »S. officinale, Linn. 1 specimen.
