Spec. Char., §c. Petiole villous. Leaflets, in a leaf, 15—17; lanceolate, 
rounded at the base, serrate with shallow teeth ; tomentose beneath ; lateral 
ones sessile. Fruit oblong-ovate, with a tapered tip, downy, covered with 
viscid matter in small transparent “ vesicles” [? glanded hairs], pendulous 
on a flexible peduncle. Nut oval, with an acuminate tip, very rough with 
prominent irregular ridges. (Miche. N. Amer. Syl., and Pursh.) A native of 
North America, near the sea coast, from Canada to Virginia, and on the 
Alleghany Mountains; where it flowers in April and May, and ripens its fruit 
in October. Introduced in 1656. 
Description, §c. The grey walnut, according to Michaux, is a tall tree, like 
Juglans nigra; of which, notwithstanding the very different form of the fruit, 
we cannot help thinking it is only a variety; because it is not very readily 
distinguished from that 
) capa by the wood or 
the leaves. We speak, 
however, only from 
what we have seen in 
young trees in the 
neighbourhood of Lon- 
don: and this seems to 
be the case with young 
trees in America; for 
Michaux observes that 
the two species, when 
young, resemble each 
other in their foliage, 
and in the rapidity of 
their growth; but that 
they are distinguishable 
at first sight, when ar- 
rived at maturity. The 
buds of the Juglans cinérea, like those of J. nigra, are not covered by scales ; and 
the leaves unfold a fortnight earlier than those of the genus Carya, or hickories. 
The leaves are composed of seven or eight pairs of sessile leaflets, with an 
odd one. The leaflets are from 2 in. to 3 in in. length, serrated, and slightly 
downy. The male catkins are large, and cylindrical, 4in. or 5in. long, and 
attached to the shoots of the preceding year; differing, in this respect, from 
the male catkins of the Jiglans nigra, which appear at the extremity of the 
branches of the current year. The fertile flowers come out on the extremity 
of the current year’s shoots, and their stigmata are rose-coloured. The fruit 
is commonly single, and suspended by a thin pliable peduncle, about 3in. in 
length: its form is oblong-oval, without any appearance of seam. It is often 
24in. in length, and 5in. in circumference; and is covered with a viscid 
adhesive substance, composed of small transparent vesicles, which are not 
readily discovered without the aid of a glass. The nuts are hard, oblong, 
rounded at the base, and terminated at the summit in an acute point; the 
surface is very rough, and deeply and irregularly furrowed. In America, in 
the neighbourhood of New York, the nuts are ripe about the middle of Sep- 
tember, a fortnight earlier than those of the a ail species of walnut. The 
kernel is thick and oily, and soon becomes rancid; hence, doubtless, the 
names of butter-nut and oil-nut. In America, the tree produces the fruit in 
such abundance, that in some seasons a person may gather several bushels of
