observes in 1819, which have been planted more than thirty years, but which donot yield fruit. He recommends the grafting of this species on the commonwalnut. In the neighbourhood of London, there are trees in the HorticulturalSociety’s Garden, and in the arboretum of Messrs. Loddiges, upwards of 20 ft.high; and accounts have been sent us of some other trees of a greater size ;but, though we have seen some of them at Purser’s Cross and other places,we are so doubtful of their identity with the kind above described by Michaux,that we can assert nothing certain respecting them. There is a tree in theJardin des Plantes, in Paris, which is 30 years planted, and 30 ft. high ; diame-ter of the trunk 9 in., and of the head 22 ft.

Description, Ac. The bitter-nut hickory grows to a very large size in Ame-rica ; Michaux having measured trees in that country 70 ft. or 80 ft. high, withtrunks from 3 ft. to 4 ft. in diameter. The leaves, which unfold a fortnight

later than those of any other species, are from 12 in. to loin, in length, andnearly as much in breadth. Each leaf is composed of .3 or 4 pairs ofleaflets, terminated by an odd one, which is larger than the rest. “ The leaf-lets are about 6 in. in length, and 1 in. in breadth ; sessile, oval-acuminate,deeply toothed, smooth, and of a pretty dark green. When the tree has shedits leaves, it may still be distinguished by its yellow and naked buds.” (JMichx.N. Amer. Syl., i. p. 171.) The peduncles of the barren flowers are in pairs,each supporting three flexible and pendulous catkins, which are attached tothe base of the shoots of the same season; at the extremities of which arethe female flowers, which are inconspicuous. The fruit is very' small, andproduced in great abundance. The husk, which is thin, fleshy, and surmountedon its upper half by 4 appendages in the form of wings, never becomesligneous, like those of the other hickories, but softens and decays. The shellis smooth, white, and thin enough to be broken with the fingers ; the kernelis remarkable for the deep inequalities produced on every side by its foldings.It is so harsh and bitter, that squirrels and other animals will not feed upon itwhile any other nut is to be found. ( Michx .) The bitter-nut hickory is anative of New Jersey and the Illinois, where it grows only in spots where the
