minutely glandular-serrate, the terminal raised on a stem 1-1 .5 cm. 
in length, the lateral nearly sessile; when they unfold scurfy- 
pubescent above and hoary tomentose below, and in the autumn 
glabrous on the upper surface, pubescent and furnished on the 
lower surface with small conspicuous tufts of axillary hairs, 6-8 cm. 
long and 1-r.5 cm. wide. Fruit ellipsoidal, acute at apex, acute 
or rounded at base, compressed, covered with small scattered yel- 
low scales, 2-2.5 cm. long, about 1 cm. wide and thick; involucre 
I-1.5 mm. in thickness, the sutures only slightly winged, tardily 
dehiscent usually only to the middle; nut oblong to slightly obo- 
void or semiorbicular, rounded at the ends, compressed, slightly 
angled, smooth and without longitudinal wrinkles, the shell 
I-I.5 mm. thick. 
A large tree with close pale bark.

A tree with close bark growing 5 miles west of Jupiter, Palm Beach County, 
Florida, with leaflets from 1.5 to nearly 2.5 cm. wide (C. S. Sargent, March 10, 
1914), is probably of this variety, but I have not seen the fruit. A number of 
trees with pale close bark on the high banks of the St. Johns River at San 
Mateo, Putnam County, Florida, seen by Mr. HARBISON and me in 1917, in 
their rather broader leaflets and larger nuts, resembling in shape the nuts of the 
typical water hickory but without their peculiar wrinkles, seem to connect the 
variety with the species. I have seen water hickories with close bark and 
narrow leaflets growing in dry sandy soil near Marshall, Harrison County, 
Texas, but the fruit of these trees has not been collected. 
5. CARYA MYRISTICAEFORMIS Nutt.—The nutmeg hickory con- 
nects the two sections A pocarya and Eucarya of the genus which 
without this species might well have been considered distinct 
genera. The valvate bud-scales and the. thin involucre of the 
fruit with prominently winged sutures show its relationship with 
A pocarya, but the thick shell of the nut and the small number of 
leaflets, 7-9 and occasionally 5, are characters of Eucarya. The 
lobes of the seed are deeply 2-lobed, like those of Eucarya, but 
this is true of two other species of Apocarya, C. cordiformis and 
C. aquatica. The seeds of these, however, are bitter, while those of
