the lower side of the midribs, 14-20 cm. long and 4-6 cm. wide. 
Fruit oblong, rounded at base, acute at apex, 5 cm. in length; 
involucre 6 mm. in thickness; nut oblong, rounded at base, acute 
at apex, compressed, slightly angled to the middle or nearly to the 
base. 
A tree with bark indistinguishable from that of C. alba with which it is 
growing, slender red-brown lustrous glabrous branchlets and acute pubescent 
terminal buds only 8-10 mm. in length. A single tree on the grounds of the 
P. J. Berckmans Nursery Company, a few miles west of Augusta, Georgia. 
_ This is one of the most abnormal hickory trees I have seen. Without the fruit 
it might easily be taken for one of the forms of C. ovalis, but the fruit and the 
nuts are clearly those of C. alba. 
10. Carya leiodermis, n. sp.—Leaves 7-, rarely 5-foliolate, 
30-35 cm. long with slender petioles and rachis slightly or densely 
pubescent with fascicled hairs, becoming glabrous or nearly gla- 
brous; leaflets thin, finely serrate, long-pointed at apex, gradually 
narrowed, cuneate and unsymmetrical at base, the terminal oblong- 
obovate, raised on a slender pubescent petiolule 1~1.5 cm. in length 
or nearly sessile, of the same shape and often smaller than those of 
the upper pair of nearly sessile lateral leaflets; leaflets of the lower 
pairs lanceolate, petiolulate, much smaller; when they unfold 
densely covered on the lower surface with hoary tomentum, pubes- 
cent above and often ciliate on the margins; fully grown in April 
when the flowers open, and at maturity dark green and lustrous on 
the upper surface, pale and slightly pubescent on the lower surface, 
those of the upper pair 12-15 cm. long and 5-6 cm. wide, with 
stout midribs more or less densely pubescent on the lower side. 
Aments of staminate flowers 10-12 cm. long, on slender puberulous 
peduncles, their bracts lanceolate, puberulous; bracts of the flower 
ovate, lanceolate, furnished on the margins with long white hairs 
mixed with stipitate glands, one-third longer than the ciliate calyx 
lobes; anthers red, covered with long white rigid hairs. Pistillate 
flowers in short spikes, their involucres and bracts densely clothed 
with long white hairs. Fruit broadly obovoid, smooth, glabrous or 
slightly pubescent, sparingly covered with small white scales, 
4~-4.5 cm. long and 3.5~4 cm. in diameter; involucre 5-5.5 mm. 
in thickness, opening freely to the base usually by 2 sutures only;
