Mrs. Hovey, as being a fine white, the "largest, doublest and best" of all his seedlings; it is of superb habit, with splendid deep green foliage, and, if it proves a pure white, it will be the greatest acquisition which has yet been made.

In our volume for 1844, (X. p. 98,) will be found an article by Mr. Pierce, upon the Prairie rose, with some remarks on its employment for hedges or live fences. In that article he states, that, having sown a lot of seeds for the purpose of stocks, "he was not a little surprised to find that he had among them twelve fine varieties of double roses." It would be gratifying to amateurs to know how he procured the seed by which he should be so very successful in producing these double varieties; whether they were from the single Prairie, or from the double varieties-or whether they had been impregnated with other sorts. We trust Mr. Pierce will find the opportunity to communicate this information, that those who wish to follow up his experiments may have some guide as to the best method to adopt to attain the end in view.

To Messrs. Feast and Pierce, the lovers of the rose are deeply indebted. Mr. Feast, we are gratified to know, has received some reward for his beautiful productions. We trust that Mr. Pierce, whose seedlings are fully equal to any which have been raised, will, in due time, also receive that token of merit which is justly his due.

ART. V. On the Propagation of Stove and Greenhouse Exotics in a Series of Letters. By JAMES KENNEDY, Gardener to S. T. JONES, Staten Island, New York.

LETTER IV. Propagation by Layers.

THERE are many kinds of Exotics, such as the Myrtus, Jasminum, Nerium, Pùnica, &c., which succeed best by this mode of propagation, and, indeed, it may be considered the most certain mode of propagation by division. The great advantage it has over any of the other modes is, that the part layered receives nourishment from its parent while roots are being formed, whereas cuttings get no further supply than

that laid up in the leaves. The state of the wood most favorable for layers is that of a medium state for ripeness; both wood and bark should be softish and not too ripe; and, above all, in a perfectly healthy state. The month of May is a favorable time for performing this work. Shoots or branches properly situated for layering, should be brought down gently, slit, and inserted into the pot of the parent plant; but when this is not convenient, let pots be filled with the soil in which the plants love to ramble, and placed conveniently near for the purpose: let them be secured firmly with wooden pegs, and cover them about two inches or so with suitable soil, over which let a little moss, or mowings of short grass, be placed to keep the earth moist. This done, give all a good soaking of water, which must be repeated regularly when necessary. As soon as roots are found to protrude, an occasional watering with clear liquid manure would be of great benefit to the young layer. At any rate, we are certain it would not do injury, and, therefore, might be applied without risk. By attending to the above hints, the shoots will be effectually rooted, and ready for potting off by the end of the summer, but, should there be any not sufficiently rooted, they must be allowed to remain till the following spring.

LETTER V. Propagation by Inarching.

When it is desired to inarch any particular kind of Exotic, the stock to be grafted on, as well as the plant from which the graft is to be taken, must stand sufficiently near each other to allow the branch, as it grows on the parent plant, to approach and join readily to that part of the stock where it is desired to be worked on, forming a kind of arch, for the graft is not intended to be cut off till some time after performing the operation; nor is the head of the stock intended to be cut off till there is a perfect union between the two. The Citrus, Pùnica, and similar exotic genera, are often propagated by this mode, on stocks raised from pips; and some genera, such as the Magnolia, Caméllia, &c. &c., are generally worked on the commoner sorts, and sometimes three or four sorts on one stock; in fact, I have seen as many as twelve varieties of the camellia on one stock, which was, indeed, a varied and imposing object when in flower.

The single red camellia is the best for stocks to work upon; it is easily propagated by cuttings; and it produces a much greater quantity of fibrous roots than any of the other sorts, and, consequently, must be able to convey a greater quantity of nutriment up into the system. The time to take off the cuttings is about the middle of May, or when the wood has become somewhat firm. They should be cut off in a horizontal direction, close at the place where they pushed from last, and smoothed off a little at the base with a sharp knife. Well-drained pots, the same size recommended for seeds and cuttings, will exactly suit. Let the pots be filled with equal parts of loam and silver sand. After inserting them tightly into the pots, give a little water to settle the soil, when they should be put in a cool frame for a week or so, and kept shaded when the sun is strong, after which they should be plunged to the rims in bottom heat, and regularly watered when necessary, and kept shaded, as above remarked.

When they have struck root, which is generally indicated by their pushing young shoots, they should be potted off singly into small pots, well drained. A compost composed of the following materials will be found suitable-To a barrowful of turfy loam,-not sifted, but chopped with the spade, add half a barrowful of well rotted cow manure; half a barrowful of peat and leaf mould; and one fourth of a barrowful of silver sand: by following this mode, the young propagator will soon have an ample supply of stocks to practise upon. Staten Island, July 28th, 1847.

ART. VI. Floricultural and Botanical Notices of New and Beautiful Plants figured in Foreign Periodicals; with Descriptions of those recently introduced to, or originated in, American Gardens.

Calystègia pubescens.-This new and beautiful climber, which we lately noticed, (p. 78), as one of Mr. Fortune's acquisitions in China, is now beautifully in bloom in our collection. Mr. Fortune sent it home as a double convolvulus.

It has much of the habit of the common bindweed of the fields, with slightly pubescent foliage, and the flowers are about the size of an anemone, irregularly double, and of a pale, delicate pink. It will probably prove a fine plant for turning out into the border in the same way as the Ipomea Learii. At present, it is extremely rare. It is a valuable acquisition to our summer flowering greenhouse plants.

16. FUCHSIA MICRA'NTHA Hook. Great-flowered Fuchsia. (Ona

graceæ.)

A greenhouse shrub: growing two feet high; with rosy crimson flowers; appearing in summer; a native of Peru; increased by cuttings; cultivated in good rich light soil. Flore des Serres, Vol. II pl. 151. 1846.

Among all the fuchsias which have been introduced, this species stands conspicuous, not only in the color of the flowers, which are of the most brilliant deep rose, but in their very large size, and the abundance in which they are produced on plants not more than two feet high. It was found in Peru by Mr. Lobb, collector for Messrs. Veitch of Exeter, and first flowered in their collection in 1845. It is one of the most desirable which has yet been introduced, having all the splendor of the F. corymbiflòra, but, unlike that variety, blooming with the ordinary care given to the common varieties. (Flore des Serres, Sept. 1846).

METHO'NICA LEOPO`LDII Van Houtte. King Leopold's Methonica, (Liliacea).

A bulbous plant; growing four feet high; with yellow flowers; appearing in summer; a native of Africa; increased by offsets; cultivated in sandy peat and loam. Flore des Serres, Vol. II. pl. 163. 1846.

Another fine plant belonging to the liliaceous tribe, and having somewhat of the noble appearance of the Japan lilies, and like them flowering in summer. It is described as having a majestic bearing, ample and deep green foliage, and large flowers of a soft yellow, marbled and striped with rose, and the colored figure fully justifies the description. It was sent home from the western coast of Africa in 1845, by the collector of Van Houtte, and first flowered at his establishment in August 1846. It is named in honor of Leopold, King of Belgium. It is of robust habit, but the stems are rather slender, and the leaves, which are recurved, have a terminal tendril which is generally curled up. The flowers are very

large, with undulated segments. It requires the same soil and treatment as the Japan lilies. Increased by offsets in the usual way. (Flore des Serres, Nov. 1846).

18. CAMELLIA JAPONICA var. LA REINE. The Queen's Camellia. (Ternstromiacea).

This is stated to be one of the most beautiful camellias which has yet been produced; of exquisite form, and of a pure white, delicately tinted with rose petals round, and finely imbricated. It history is not known; but it was procured by Van Houtte of an amateur cultivator, whose taste for the camellia was so nice that but few varieties were esteemed of sufficient excellence to deserve cultivation : it has also been pronounced, by the principal amateur cultivators of Gand, "one of the three best camellias known." (Flore des Serres, Nov. 1846).

ABU TILON PÆONIFLO`RUM Nob. Pæony-flowered Abutilon.

(Malvacea).

A greenhouse plant; growing four feet high; with deep crimson flowers; appearing in summer; a native of Brazil; increased by cuttings; cultivated in peat, loam, and sand. Flore des Serres, Vol. II. pl. 170. 1846.

A pretty species of the abutilon, with bright rose-colored flowers, and pubescent foliage, attaining the height of three or four feet, and flowering in clusters at the ends of the branches. For out-door cultivation in summer, it will probably become a very ornamental object. Cultivated in any good soil, and increased by cuttings. (Flore des Serres, Nov.)

20. LESCHENAULTIA SPLENDENS Hook. Splendid flowered Leschenaultia. (Goodeniacea.)

A greenhouse plant; growing a foot high; with scarlet flowers; appearing in spring; a native of New Holland; increased by cuttings; cultivated in peat, leaf mould, and sand. Flore des Serres, Vol. II. pl. 176. 1846.

The beauty of the well known Leschenaúltia formosa, is familiar to all cultivators. L. spléndens is of the same habit, but more robust, and the flowers have all the brilliancy of the old Verbena Melindres, being deeper and brighter than formòsa. It was introduced into England by Messrs. Lucombe & Pince, and a plant exhibited by them in 1846 had upwards of three hundred flowers expanded. It should be introduced into every fine collection of plants. Its cultivation is the same as for the other species. (Flore des Serres, Dec).
