Carpinus viminea[4] is a rather striking species with long-pointed leaves; the accompanying figure scarcely gives a sufficiently clear representation of their long, tail-like prolongations.  Judging from the height at which it grows, it would probably prove hardy in this country, and, if so, the distinct aspect and graceful habit of the tree would render it a decided acquisition.  It is a moderate-sized tree, with thin gray bark, and slender, drooping warted branches.  The blade of the smooth leave measures from 3 inches to 4 inches in length, the hairy leaf-stalk being about half an inch long.  It is a native of Himalaya, where it occurs at elevations of from 5000 to 7000 feet above sea-level.  As in our common hornbeam, the male catkins appear before the leaves, and the female flowers develop in spring at the same time as the leaves.  The hard, yellowish white wood—­a cubic foot of which weighs 50 lb.—­is used for ordinary building purposes by the natives of Nepaul.

FRUIT OF CAMELLIA JAPONICA.

The fruiting of the camellia in this country being rather uncommon, we have taken the opportunity of illustrating one of three sent to us a fortnight ago by Mr. J. Menzies, South Lytchett, who says:  “The fruits are from a large plant of the single red, grown out of doors against a wall with an east aspect, and protected by a glazed coping 4 feet wide.  The double, semi-double, and single varieties have from time to time borne fruit out of doors here, from which I have raised seedlings, but have hitherto failed to get any variety worth sending out or naming.”

In the annexed woodcut the fruit is represented natural size.  Its appearance is somewhat singular.  It is very hard, and has a glazed appearance like that of porcelain.  The color is pale green, except on the exposed side, which is dull red.  It is furrowed like a tomato, and on the day after we received it the furrows opened and exposed three or four large mahogany-brown seeds embedded in hard pulp.—­The Garden.
