rare, and trees producing such nuts occur in eastern Pennsylvania 
and are generally distributed through the southern states. Such 
pointed nuts are usually acute or acuminate at base and are 
inclosed in involucres which are oblong, gradually narrowed and 
rounded at base, and acute or acuminate at apex; but a tree at Noel, 
Missouri, produces ovoid fruit broad and rounded at base and 
gradually narrowed and rounded at apex, which is so different from 
that of other forms of this species which I have seen that it may be 
distinguished as 
CARYA ALBA var. ovoidea, n. var.—Differing from the type in 
its ovoid fruit with a thinner tardily dehiscent involucre. Leaves 
small for the species, not more than 20 cm. long, with densely 
pubescent petioles and rachis, and 7 thin leaflets. Fruit smooth 
and lustrous, not at all compressed, 3 .5-4.5 cm. long and 2 .5—-3 cm. 
in diameter; involucre not more than 4 mm. in thickness, remaining 
entirely closed or opening tardily by 2 or 3 of the sutures nearly 
to the middle. Nut rounded at base, gradually narrowed into a 
long acuminate apex, irregularly ridged to below the middle, much 
compressed. 
A tree 15 m. high with rough ridged gray bark.

On the grounds of the P. J. Berckmans Nursery Company, a few miles 
west of Augusta, Georgia, there is a hickory tree which bears the large oblong 
acute fruit and acuminate nuts rounded at base of one of those extreme forms 
of C. alba which produce pointed nuts. The bark of this tree is indistinguish- 
able from that of a tree of C. alba which is growing close to it. It has glabrous 
branchlets, however, as slender as those of C. ovalis, and acute pubescent ter- 
minal winter-buds 8-10 mm. long. The leaves are 7-foliate with thin leaflets 
and are only slightly pubescent. C . pallida grows near this tree, and there are 
individuals of C. glabra not far off. I should have suspected that this tree 
might be a hybrid between C. alba and one of these species, but I can find no 
trace of either of them in the fruit which is distinctly that of C. alba. It may 
be described as 
CARYA ALBA var. anomala, n. var.—Differing from the type in 
its nearly glabrous leaves with smaller leaflets, in its slender glabrous 
branchlets, and in its smaller winter-buds. Leaves 7-foliate; 
petioles and rachis only slightly pubescent; leaflets thin, acuminate, 
finely and remotely dentate, puberulous below and pubescent on
