A correspondent who is a good judge of greens, complains that we have never recommended one of the most of which may be had at Thorburn's or any other of the large seed stores. Ed.

New Zealand Spinach, (Tetragoniacxpansa,) so called, because it was found growing wild on the shores of New Zealand when Captain Cook first touched at that island. Although the natives made no use of this plant as an esculent, the naturalists who accompanied the expedition were induced to recommend it as a vegetable which might be safely eaten, since its appearance and general characteristics were so similar to the Chenopodiura. On trial, it was found to be both agreeable and wholesome. Sir Joseph Banks brought it into culture in England in 1772, and it has subsequently been found to be a much more hardy and valuable plant than was at first supposed. It was at first treated as a green-house plant: but now grows freely in the open garden, and indeed seems already to have naturalized itself in-the south-west of England. A writer, from Exmouth, observes, in the "Gardener's Magazine" for February 1829, "The New Zealand Spinach is quite a weed with us, as, wherever it has once grown, plants rise spontaneously, even when the seeds have been wheeled out with the dung in the the winter, and again brought in as manure in the spring.

I have now a full supply of it in my old pink bed." This Spinach has an advantage over the common sort under cultivation, in producing an abundance of large and succulent leaves during the hot weather, when the latter plant runs almost immediately to seed, and produces little or nothing. It is likewise milder in flavor, and of so rapid growth, that a bed with about 20 plants is sufficient for the daily supply of a large family. Though by some called a biennial, this Spinach is an annual in our climate. The stem has numerous thick and strong branches, somewhat procumbent for the greater part of their length, but raised at the points. The leaves are fleshy and succulent, three or four inches long, of a dark green on the under part, but of a paler color on the surface, on which the midribs and nerves are strongly marked. They are triangular, or rather of an elongated heart-shape, having the angles at the base rounded, and the apex sharp and extended. The flowers are small, and of a yellowish green color; they appear in August and September. The whole plant is thickly studded with minute aqueous tubercles; a peculiarity likewise to be found in some species of atriplex and chenopodinm. In six weeks after sowing, some of the leaves of the plants are fit for gathering.

These are pinched off. and not torn from the branches. This plant has been likewise found growing on the Tonga islands; and Thumberg discovered it of spontaneous growth in Japan. New Zealand Spinach is remarkable as being almost the only native of the isles of Australasia which has been found opposite to the common Spinach, as it will endure the heat better than the cold. It may be obtained in the summer by planting the seed in April or May - (he might have added June.) Being of luxuriant growth, it should be planted in hills three feet apart and about two seeds in a hill. The leaves will be fit for use during the summer and until lute in the autumn." Yours, E. New-York, May, 1851.

New Zealand Spinach #1

P. B. Mead, Esq. - Dear sir: I note article on above in April number. I beg to say that I do not think it a desirable vegetable for this latitude. It is good, but does not come in at the right season. Kidney and Lima Beans, Egg Plants, Squash, and Tomatoes, take the preference, when it is at its prime, and it stands unpicked; at least this is my experience. Frost spoils it. I think, with Mr. More, it would be valuable South. It could there be grown for Spring and Fall, as the common is with us. If he and yourself will notice this season, believe you will find that you do not care for greens in midsummer.
