The slender often glabrous branchlets of C. leiodermis show its relationship 
with C. ovalis; the close bark, the thick involucre of the fruit, the reddish nut, 
and the pale tomentum on the under surface of the young leaflets indicate a 
connection uo C. alba, and its proper position seems to be between these 
two specie 
CARYA LEIODERMIS, var. callicoma, n. var.—Differing from the 
type in the thinner involucre of the fruit and in the bright red color 
of the unfolding leaves. Leaves 7-foliate, the young leaflets coated 
below with hoary tomentum, ciliate on the margins and scurfy- 
pubescent above, bright red and very fragrant, and at maturity 
thin, dark green and lustrous on the upper surface and yellow- 
green and nearly glabrous on the lower surface. Fruit slightly 
obovoid, smooth, nearly glabrous, usually 3-3.5 cm. long or rarely 
not more than 2 cm. long; involucre 2.5—3 mm. in thickness, open- 
ing tardily nearly to the base by 2 or 3 sutures; nut rounded at 
the ends, compressed, only slightly angled, pale brown, 1.5-2.5 cm. 
long and wide, the shell 3.5 mm. in thickness.
