MEMOIRS or THE XEW YORK BOTAXICAL GARDEN 



Remains of leaves and nuts of hickories are abundantly rep- 

 resented in American Pleistocene deposits. Leaves referred to 

 Hicoria ovafa, under the name Gary a alba Xuttall, from the 

 interglacial dejDosits of the Don Valley, near Toronto, Canada, 

 were recorded by Penhallow," but without any illustration. The 

 same species, represented by two incomplete terminal leaflets, 

 was also recorded by Berry,^ but not figured, in a list of Pleisto- 

 cene plant remains, from deposits on the Neuse River, North 

 Carolina. In a subsequent paper the same author*' described 

 and figured specimens of leaflets from the Pleistocene of the 

 same State, some of which he referred to Hicoria glabra {op. 

 cit., p. 106, pi. 46, figs. 1^), and some to H. ovata {idem, figs. 

 6, 7). Those referred to H. glabra may be seen to compare quite 

 closely with ours, both in size and general appearance. He also 

 cites Hicoria pseudoglahra Hollick,^ from the Pleistocene of 

 Maryland, as a synonym of H. glabra. In no instance, however, 

 has a complete leaflet been preserved, and adequate or satis- 

 factory comparison is impossible, either in connection with the 

 fragmentary fossil remains or between them and leaves of exist- 

 ing species. Nuts and husks of Hicoria ovata, and of Hicoria 

 glabra, were also listed by Berry^ from Pleistocene deposits in 

 Virginia, Maryland, and New Jersey; and similar remains, de- 

 scribed and figured by Mercer,^ are abundantly represented in
