104 FLORA OF SOUTHERN NEW YORK AND NEW ENGLAND. 



Diospyros provecta Velenovsky, 



PL XL, figs. 7-10. 



Diospyros provecta Vel., Fl. Bohm. Kreideform., pt. 3, 1884, p. 2 (49), pi. 8 (23), figs. 1-5, 10. 

 Rhamnus Pfaffiana Heer, Hollick, Trans. New York Acad. Sci., vol. 11, 1892, p. 103, pi. 4, fig. 1. 

 Diospyros Steenstrupi Heer, Hollick, Trans. New York Acad. Sci., vol. 12, 1892, p. 34, pi. 3, fig. 8. 

 Myrsine elongata Newb, Hollick, Bull. New York Bot. Gard., vol. 2, 1902, p. 405, pi. 41, fig. 2. 



These leaves, which all show the characteristic nervation of Diospyros, are 

 hardly separable from some which may be found included under D. apiculata Lesq. 

 in this monograph. The latter, however, are generally broader and with the sec- 

 ondary nervation diverging at a somewhat more obtuse angle. The Tertiary species 

 D. brachysepala A. Br. a is more nearly like our figures than is either of the others 

 mentioned, as may be seen by a comparison with the figures by Heer, 5 but it is haz- 

 ardous to regard this species as having such a great vertical range as identity between 

 them would imply. 



A narrow form of D. primxva Heer c is almost certainly identical with D. pro- 

 vecta Vel., as here recognized, and in any revision of the genus I would have no hesita- 

 tion in so including it.

Diospyros pseudoanceps Lesquereux. 



PL XL, fig. 3. 



Diospyros pseudoanceps Lesq., Mon. U. S. Geol. Survey, vol. 17 (Fl. Dak. Gr.), 1892, p. Ill, pi. 22, fig. 1. 

 Diospyros primseva Heer, Hollick, Trans. New York Acad. Sci., vol. 12, 1893, p. 236, pi. 7, fig. 5; Fifty -fifth 

 Ann. Rept. New York State Mus., 1901 (1903), p. r51. 



There seems to be but little doubt that our specimen is identical with this 

 species, according to the single figure given by Lesquereux (loc. cit.), but it must be 

 admitted that some of the specific distinctions recognized in this genus are not 

 altogether satisfactory. 



Locality: Glen Cove, Long Island. Collected by Arthur Hollick. Specimen in 

 Mus. New York Bot. Gard. 



Diospyros prodromus Heer?. 



PI. XL, fig. 12. 

 Diospyros prodromus Heer, Fl. Foss. Arct., vol. 3 (Kreide-Fl.), 1874, p. 113, pi. 28, fig. 6c; pi. 32, figs. 3-7. 



Heer's figures of this species are not very satisfactory, but his fig. 3 agrees essen- 

 tially with ours, in which the characteristic horizontal tertiary nervation of the 

 genus is discernible to a limited extent.
