Order JUGLANDALES. 



Family JUGLANDACEAE. 



Genus HICORIA Rafinesque. 



HICORIA PECAN (Marsh) Britton. 



Carva olivaeformis Nuttall, Lesquereux, Amer. Journ. Sci., eer. 2, vol. 27, 1859, 

 p. 365. 



Both leaflets and nuts were recorded by Lesquereux from the 

 Chalk Banks near Columbus in 1859. I found no nuts, but the 

 leaflets are very common in the bluffs both north and south of Colum- 

 bus and sparingly represented at Hickman. One specimen collected 

 showed the terminal and two pairs of lateral leaflets attached to the 

 rachis. This occurrence would seem to lend considerable weight 

 to the theory advanced by Mohr and others that the pecan is indige- 

 nous in the eastern Gulf region. 



HICORIA GLABRA (Miller) Britton. 



Carya porcina Nuttall, Mercer, Journ. Acad. Nat. Sci. Phila., ser. 2, vol. 11, 1899, 



pp. 277, 281, figs. 4, 5, 8, 12, 16.

The pignut hickory has been recorded from a number of Pleistocene 

 localities in New Jersey, Pennsylvania, Maryland, Virginia, and 

 North Carolina, being represented by nuts, husks, and leaves. A 

 characteristic large terminal leaflet was found at Hickman and a 

 less certainly identified lateral leaflet was collected at Columbus. 



This species is, with the exception of the pecan, our most southerly 

 ranging hickory, reaching its present maximum development in the 

 lower Ohio River basin, and it is certainly significant in its bearing 

 on local Pleistocene climates that these two species should be found 

 fossil in western Kentucky. 



Order SALICALES. 

 Family SALICACEAE. 



Genus SALIX Linnaeus. 



SALIX VIMINALIFOLIA, new species. 



Leaves linear-lanceolate in outline, of relatively large size, about 

 15 cm. in length by 2.25 cm. in maximum width, gradually narrowed 

 to the acuminate tip and somewhat abruptly narrowed to the broadly 

 cuneate base. Margins entire in all of the specimens collected. 

 Venation typical of Salix.
