35. THE GUELDER ROSE OR SNOWBALL TREE, (Viburnum O'pulus var.) Too common and well known to need more than a passing notice, as no shrubbery should be without one or more plants. It thrives in any good soil, and its globular heads of snowy flowers are always admired. May and June. 36. DOUBLE-FLOWERING CHERRIES, (Cérasus sylvéstris fl. pl.) There are three kinds of the double flowering cherry, two only of which have yet flowered in our collection. The first is the common double cherry, (sylvestris fl. pl.) with very compact flowers, like a ranunculus. The other, the double French, (vulgaris fl. pl.) with larger and more loosely formed flowers, and expanding a fortnight before the former,—thus keeping up a succession of bloom, during nearly the whole of May and June.

37. WEEPING CHERRY, (Cérasus semperflòrens.) A handsome weeping tree, grafted standard high, with small linear foliage, and slender branches, producing flowers and fruit a greater part of the summer. As single objects on lawns, a few of these trees have a beautiful effect.

38. THE CHINESE CRAB, (Pyrus spectabilis.) One of the showiest of double flowering trees, the branches being literally covered with pink flowers, as large as a small rose. Unless properly pruned, it only blooms every other year. May.

39. HAWTHORNS, (Cratæ`gus.) There are a great number of fine species and varieties, which comprise the extensive family of hawthorns, that are well worthy a place, wherever there is room; a few of them are particularly beautiful, and should, on no account, be omitted in the smallest collection. There are the double white, (C. Oryacántha múltiplex,) the new double pink, (C. O. ròsea plèno,) and the old single scarlet, (C. O. punicea.) The last, though single, a most brilliant shrub; the double pink has flowers as perfect as the ranunculus; all of them bloom profusely, but, to have handsome specimens, they should be annually pruned, and be allowed plenty of room, or otherwise their real beauty is greatly marred. We have thirty sorts in our collection. May and June.

40. THE LABURNUM, (Cytisus Labúrnum.) A very pretty shrub, on account of its numerous large pendant clusters of golden yellow blossoms. The Scotch is the hardiest and finest

kind. There is a weeping variety, which forms a most graceful and ornamental tree, when grafted standard high. They are partial to a dry subsoil. Flowers in May.

There are many other shrubs which ought to be included in this list; such as the Amelanchiers, Pavias, Spiræas, Pyruses, Lilacs, &c., &c., but we have already extended our limits, and must defer them to another opportunity.

II. EVERGREEN SHRUBS.

Growing from two to six feet high.

41. RHODODENDRONS, (Rhododendron sp. and var.) We have, from time to time, said so much in favor of the general introduction of this splendid evergreen shrub, into our gardens, that we shall not extend our remarks here.

The catawbiénse and maximum, our two native species, demand a place in every shrubbery: but preeminently beautiful are the English hybrids, produced from the seeds of these, and the foreign kinds. They are perfectly hardy, thrive. freely in a well prepared soil of loam and leaf mould, and display their heads of brilliant flowers, during the month of June. When they become more plentiful in the nurseries, we hope to see them planted in every garden.

42. LAUREL, (Kòlmia latifòlia.) This most elegant of all evergreen shrubs, though so common throughout the State, ist rarely seen under cultivation. In Medfield, and at Cohasset, and near Newburyport, and Lowell, it grows abundantly. Mr. Emerson, in his Report on the Trees and Shrubs of Massachusetts, says, that in "a rocky pasture of several acres, near a pond, in Westboro', it forms large close clumps, or islets, intersected by plats and alleys of grass. In June and July, when every one of these innumerable green islets, is covered with white or rose-colored flowers, and the cattle are feeding on the grass, or lying under the few oaks which are scattered through the pasture, the whole, with the lake and its fringe of trees, is worth going out of one's way to see."

It is impatient of removal from its native habitat, and the only way to possess it, is to raise it from seeds. In this way, the bushes are dwarf and stocky, and will bear removal, even when of large size, as safely as a currant-bush. The soil should be composed of loam and leaf mould, or peat earth.

43. HOLLY-LEAVED BERBERRY, (Mahònia aquifòlium.) A handsome shrub, from the Rocky Mountains, but quite hardy in latitude 42° north. It is a very compact dwarf growing shrub, with leaves similar to the holly, and with a profusion of clusters of handsome yellow flowers, which appear at the ends of the branches. In winter, the foliage becomes rather brown, but, in summer, it again assumes its deep green glossy tinge, and is a most valuable acquisition to this class of plants. It thrives under the shade of other trees, and any light soil will suit it. April and May.

44. THE WINTER BERRY, (Prinos glàber.) A very pretty evergreen shrub, growing in sheltered places in Plymouth and Hingham, with narrow leaves, of a deep glossy green. Flowers white, inconspicuous, and succeeded with small black berries. Its greatest merit is the beauty of its foliage, which is at all times green and glossy. The same soil as that for the Kalmia, suits the winter berry. July and August. 45. TREE BOX, (Búxus sempervirens var.) The Tree Box forms a very handsome pyramidal tree, attaining, after many years, the height of ten or twelve feet, but we have seen fine specimens twenty years old, which were not six feet high. There are several varieties, but the two best known in our gardens, are the broad-leaved, and narrow-leaved; both are hardy, grow freely, are highly ornamental, and should be found in every garden.

With this rather long list, extended, because we could not well leave out any of them, the amateur can make a selection suitable for a small or large garden. And if it shall aid in making the several kinds better known, and more generally introduced into collections, our object in writing it will have been accomplished.

ART. II. Fungi in Vegetation. By JOHN LEWIS RUSSELL, Professor of Botany, &c. to the Massachusetts Horticultural Society.

BEING very much interested in an article which appeared in your February number on "Destruction of Filberts by Fun

gi," as suggestive of many important investigations, I applied to the writer for specimens of what he considered Cryptomyces Wauchii. With great readiness Mr. Goodsell kindly forwarded to me several specimens, of which he says:

"Since the receipt of yours, I have examined, perhaps, fifty filbert plants that were injured last season, as I supposed, by the fungi, without being able to find a single specimen exhibiting its summer appearance-the side where the fungi made their appearance is uniformly dead-the outer bark separated from the inner, which is covered uniformly as on the specimens enclosed."

By submitting these to a powerful magnifying lens, I could perceive no structure of the fungi, which would ally them to any known form with which I am acquainted; and, indeed, there was nothing which would indicate that these specimens were any thing more than the dead remains of some sort of parasitic growth. To the genus Cryptomyces belong fungi which burrow between the wood and bark of whatever plant it infests; and the general description in the article referred to seems to point out the plant as Mr. G. intimates. I shall therefore feel greatly obliged to him for perfect specimens next summer, as he promises me.

It may not be familiar to the reader, that some of these lower forms of vegetables, e g. the parasitic fungi, have a very beautiful internal organization, consisting of a sort of seed vessels called technically asci, and other peculiarities beside. Deeper powers of the microscope are requisite to develope them than are commonly at hand. As objects, therefore, of curiosity and elaborate beauty, or as subjects for the care and prudent inspection of the agriculturist, these injurious forms of vegetable life address him and call upon his attention, as the article very properly suggests. I hope that they will be accordingly studied, and made worthy of investigation, as your Rochester correspondent has set so good an example, by moving in so important a matter.

Hingham, March, 1849.

The subject of fungi in vegetation is one of much interest, and, we trust, will receive the attention of all cultivators. We shall be glad to have Mr. Russell and Mr. Goodsell pursue the matter further.-Ed.

ART. III. Notices of Culinary Vegetables, new or recently introduced, worthy of General Cultivation. By the EDITOR.

NOTWITHSTANDING four years have elapsed, since our last notice of new vegetables, under this head, only a limited number of new and desirable kinds, have been introduced, during that period. Some of these have been incidentally noticed, from time to time, but we now embrace the opportunity, to bring them together, and give a more detailed account of their merits. We begin with

PEAS. Every year adds to the catalogue of varieties offered for sale, by seedsmen, but most of them vary so slightly from each other, that they soon go out of cultivation, or attract but little attention. A few only possess merit sufficient to recommend them for general use. Among those of the latter description, are the following :

Champion of England. This is one of the most remarkable varieties that has recently been produced. It is one of the marrow peas, blue, and exceedingly shrivelled, and, in richness of flavor, surpasses all other peas that we have ever eaten. It is not only one of the tenderest fleshed sorts, but it is more sugary than any other variety. It grows about two feet high, produces well, and it must be ranked at the head of all the peas of its class, yet raised.

Flack's Victory we have already noticed, and we now allude to it, to remark, that the experience of three years has fully confirmed all we said of it. It is a large delicious variety, and must form one of a succession of peas in every garden.

Fairbeard's Early Surprise. This is another variety, produced by the same cultivator, who raised the Champion of England, and although it is now introduced into our collections, for the first time, it will, undoubtedly, prove a fine pea. It is as early as the Early Frame, and has the flavor of Knight's Marrow. We shall speak of it, after a fair trial.

Other new ones are Burbidge's Eclipse, a large blue marrow, 15 inches high; Early Danecroft, the Early Emperor, &c. HOO-SUNG, OR 00-SUNG. This is the name of a new Chinese vegetable, brought home by Mr. Fortune, in his Chinese expe
