vegetating Walnut. — This is a most valuable variety for those dis- j

tricts where the frosts continue late in spring. In France , about jParis , its leaves do not appear before the end of June; but the fruitripens nearly as early as that of the other varieties. In the LondonHorticultural Society’s Garden, there is a plant of this variety, 5ft.or 6 ft. high, which, on the 1st of July, 1835, when every other tree inthe garden was in leaf, had not burst a single bud.

Other Varieties. The above are the most remarkable and valuable of thevarieties of the common walnut; the first three, on account of their fruit;and the last, as a curiosity, on account of its leaves. But in the Bon Jardkiafive others are enumerated; and in the Horticultural Society’s Fruit Cats- 'logue for 1832 nine are given, of which the most valuable for cultivation for its Jfruit is the highflier; a variety which was originated at Thetford , in Norfolk , .and which is held in much esteem in that county and in Suffolk. (Hort |Trans., iv. p. 517.; and E. of Gard., ed. 1835, p. 942.) There is also the fYorkshire walnut, which is much planted in that county. The varietiesrecommended by Mr. Thompson, as having proved the most prolific in theHorticultural Society’s Garden, are, the round early oval; the double largeFrench , No. 1. above; the tender-shelled, No. 2.; and the thick-shelled. j

A variation, worth notice, was displayed in a nut sent to us by Mr.Samuel Taylor of Whittington, near Stoke Ferry, Norfolk , which hadnearly three perfect valves, but was devoid of kernel.

Description. The walnut forms a large and lofty tree, with strong spread-ing branches. The leaves have three or four pairs of leaflets, terminated by®odd one, which is longer than the rest. The male catkins are pendulous, a»“are produced near the points of the shoots. The bark is thick, and deeply ,furrowed on the trunk; but on the upper branches it is grey and smooth. ;The leaves, when bruised, exhale a strong aromatic odour; and, in the es 'treme heat of summer, the exhalations from them are so powerful, as toproduce unpleasant effects upon some persons, if they slumber under the
