DESCRIPTIONS OF SPECIES. 83 



Platanus sp. 

 PI. XXXI, fig. 5. 

 Platanus Newherryaiw, Heer, Hollick, Trans. New York Acad. Sci., vol. 11, 1S92, p. 103, pi. 4, fig. 9. 



The original unquestioned reference of this specimen hj me to P. Newherryana 

 Heer was manifestly not warranted by its fragmentary character, although there 

 can be but little doubt that it represents a portion of a Platanus leaf.

, Amelanciiier Whitei n. sp. 



PI. XXXII, fig. 1. 



Leaf 6 centimeters long by 2.5 centimeters wide in the middle, elliptical-lanceolate in outline, tapering 

 above, rounded to the base, short petioled, finely and uniformly serrate-dentate almost to the base; secoudai-y 

 nerves curving upward from the midrib at acute angles; tertiar}' nervation fine, subparallel, almost horizontal 

 or slightly curved downward. 



This leaf apparently belongs to Amelanchier or some closely allied genus, and 

 the indications are that it had a somewhat abruptly attenuated or tapering apex. 

 There does not seem to be anj^ described Cretaceous species with which it may be 

 identified, but it is closelj^ similar to A. typica Lesq., from the Tertiary of Floris- 

 sant, Colo." Named for Mr. David White, the collector.

Hymen^ea dakotana Lesquereux. 



PI. XXXII, figs. .5-7. 



Hymenxa dakotana Lesq., Mon. U. S. Geol. Survey, vol. 17 (Fl. Dak. Gr.), 1892, p. 145, pi. 55, figs. 2, 3; 



pi. 56, figs. 1,2; pi. 62, fig. 2; Hollick, Bull. Torrey Bot. Club, vol. 21, 1894, p. 56, pi. 176, fig. 4. 

 Dalhergia RinJciavM, Heer, Hollick, Trans. New York Acad. Sci., vol. 12, 1893, p. 236, pi. 6, fig. 5. 



The distinction between this species and Dalhergia Rinhiana Heer'' is hardly 

 discernible, but Lesquereux's figures are much better defined, and comparison 

 with these is therefore more satisfactory. Our fig. 5 is practically identical with 

 Lesquereux's fig. 2, pi. 56, and our fig. 6 may be compared with his fig. 3, pi. 55.
