sand to keep the mass porous. Great care should be exercised in watering, as the plant invariably "goes off" if the soil becomes sour to the smallest extent through excessive moisture, though it may be speedily replaced, as seedlings grow rapidly, and the seeds are freely matured. Solanum jasminoides is another good cool-house plant. It is a free grower, and makes a singularly elegant covering for columns or rafters. The flowers, borne in large pendent clusters, are bluish white, often pure white, with a showy bunch of yellow stamens in the centre of each. The plant will make satisfactory progress in any ordinary potting soil, but preference should be given to that of a loamy character. Stephanotis floribunda is an old and deservedly popular occupant of our stoves. The large oval leaves are opposite, leathery in texture, and of deep green color. The tubular flowers, with spreading five-lobed limb, borne profusely in large axillary clusters, are pure white, of waxy substance, and deliciously fragrant. It is an admirable plant for any purpose in which a climbing plant may be utilized, and grows well in any compost, the chief constituent of which is rich loam. When grown in pots-for which purpose it has no rival in beauty-it should be rested in winter and pruned sparingly, removing, however, all superfluous material. After repotting in spring, the old stems and branches should be carefully trained to a trellis, allowing the young shoots, when they appear, to twine around strings attached to the roof of the house. It flowers more freely where this system is followed, and the new branches can be taken down and attached to the trellis, just before the flowers expand, without serious trouble. Stigmaphyllon ciliatum, the Golden Vine, a somewhat uncommon but very attractive plant, requires an intermediate temperature. It soon covers a large area, its cordate, ciliate, pale green leaves forming a close mass. The large Oncidiumlike flowers are of deep golden-yellow color, and freely produced in clusters of fair size. It thrives vigorously in a mixture of loam; peat, leaf-mold and sand. Tacsonia Van Volxemii is a magnificent plant, with flowers resembling in shape those of the Passion Flower, to which, indeed, it is closely related. They are from four to five inches in diameter, and deep rich crimson. The plant should be trained in the same manner as Rhodochiton volubile, and thrives satisfactorily under the same conditions, adding peat to the compost. Cambridge, Mass. M. Barker. Roses. AT this season there is but little to be done among outdoor Roses, except to give the usual attention to cultivation and watering, the latter being of no value unless done thoroughly, while the cultivation is especially necessary during dry weather. As the nights become cooler the Teas will produce better flowers, but it should always be remembered that outdoor flowers, as well as those grown under glass, will be much improved by being cut early in the morning and immediately placed in water. This method improves both the size and color of the flowers, besides making them more durable. Hybrids for early forcing will now be ripening their growth, and will naturally need less water in order to hurry this process, for it will be remembered that the earliest crops require much more time for their development than those that more nearly approach the natural flowering season. The most serious pest the Rose-grower of the present day has to contend with appears to be the nematodes, or eel-worms, to which frequent reference has been made during the past year in GARDEN AND FOREST and other horticultural journals. Unfortunately, no specific has thus far been discovered for this pest, the various so-called remedies having all failed under the careful tests of specialists. The most reasonable suggestion that has been offered for their destruction is that of baking or cooking the soil before placing it in the Rose-beds; but this is an operation of considerable magnitude even in a small establishment, and where Roses are largely grown it becomes a very formidable undertaking. It has been suggested that a portable oven of large size and heated by means of steampipes would solve the difficulty; but the expense of such an arrangement would work against it in many establishments, especially in those in which the present heating apparatus is not suitable for such purpose. Lime in various forms has been given thorough tests in several places during the past season and apparently has no effect whatever on the eel-worms, and tobacco extract (which has also been recommended) has not proved any more effectual. The beautiful Tea-rose Cornelie Koch is more rarely seen since the advent of the Bride, which is a much freer bloomer. 429 During hot weather the Bride is of little value, however, and then Cornelie Koch proves quite useful. In the winter Cornelie Koch, though producing large and fine flowers, is not to be compared with the Bride. At least one of the new American pedigree Roses has attracted some attention from cut-flower growers, for I recently saw a bench one hundred feet long filled with Golden Gate. The grower seemed well pleased with it, and claimed it to be of about the quality of Safrano. The flowers of Golden Gate are not very large, but are pretty in the bud, and the plant is generally well spoken of as an outdoor bedder. Another new Rose of much promise, though not of American origin, is Empress Augusta Victoria, a hybrid Tea that was slightly tested last winter, and will have more extended trial during the coming season. In color, this rose is white, and the flowers are shaped somewhat like those of the Bride, the petals having good substance, and in addition to this the blooms are delightfully fragrant. The growth of this variety seems strong and the foliage is of good texture, while much is claimed for its free blooming. It seems unfortunate that so promising a variety as Waban once appeared to be should have proved so unsatisfactory as it has done. It is possible that all the fault did not lie with the variety, as it is more than probable that overpropagation so enervated the stock as to injure what might otherwise have been a useful variety. Holmesburg, Pa. W. H. Ta)lin. Iris Lorteti. THIS most beautiful Iris, belonging to the Oncocyclus section, was discovered some years ago between Meis and Hounin, in South Lebanon, by Dr. Lortet, the accomplished naturalist of Lyons. It was described by Barbey, Herborisalions aiu Levant, p. I78, 1882, who there gives a large colored figure of it. Thanks to the unwearied'zeal of Mr. Max Leichtin, a considerable stock of roots has recently been imported from Palestine. The Oncocyclus group of Irises is best known through Iris Susiana, which has been in cultivation in western Europe for more than two hundred years, and is still more widely grown than any other member of the group. I. Susiana has its home in western Persia, and stretching away toward the Caucasus lives the next best-known, I. Iberica. This part of the world may, indeed, be regarded as the centre of the group, and as we pass westward along the southern regions of Asia Minor we find several forms, more or less closely allied to I. Susiana, all of them beautiful. Near Mardin grows the lovely I. Gatesii, not far off the striking I. Heylandiana, more to the west, in Cilicia, the handsome I. Saari, and in Palestine is found an Iris which, sent to me from the neighborhood of Nazareth, I exhibited at the Royal Horticultural Society some two or three years ago under the provisional name of I. Saari, var. Nazarena. Iris Lorteti, in general features, comes very close to I. Saari, and especially, perhaps, to I. Nazarena, but its wonderful coloring puts it by itself as, perhaps, the most beautiful Iris in the world. In the specimens gathered by Lortet, the outer segments are described and figured as showing a very pale blue ground covered with crimson spots, which, scattered sparsely over the marginal parts of the fall, are concentrated into a dark crimson patch or "signal" in the centre beneath the end of the style; the inner segments, or standards, are similarly described as being of a delicate pale rose. In a plant flowered this summer by me, the falls showed a creamy yellow ground marked with crimson spots, concentrated at the centre into a dark crimson signal, while the standards were nearly pure white, marked with very thin violet veins hardly visible at a distance. I learn that the plants imported by Mr. Max Leichtlin show considerable variation in color; apparently, however, the "note" of the plant is a peculiarly charming combination of crimson spots, and blue or violet veins, on a white or creamy yellow ground. The flower figured by Barbey is as large as that of an ordinary, or rather smaller I. Susiana. It is perhaps hardly necessary to add that the flower has the characteristic features of its allies; an oval fall convex from side to side as well as re flexed vertically, bearing a loose beard of scattered hairs, an orbicular, erect standard, and a nearly horizontal style lying close on the claw of the fall, and bearing conspicuous semlicircular crests. Barbey describes the leaves as being very narrow, though his figure somewhat contradicts this, and in the plants grown by me the leaves are very distinctly broader and more ample than in I. Susiana; indeed, it appears to me to promise a larger foliage than is possessed by any other Oncocyclus Iris. SEPTEMBER 7, I892.] Garden and Forest.
