36. NIPHÆ A RUBIDA Hooker Reddish Niphæa. (Gesner
aceæ.) A greenhouse plant; growing one foot hizh ; with white flowers ; appearing in summer ; a native of Mexico; (?) increased by offsels ; grown in peat, leaf mould, and sand. Flore des Serres, pl. 251. 1617.
A much more beautiful species than the old oblonga, not only in the more numerous flowers, but in their size; the flowers are white, and borne on long peduncles, forming large clusters. The leaves are also handsome. It was introduced into England and Belgium about the same period. (Flore des Serres, foc., July.) 37. GARD`ENIA MALLEIFERA Hook. Clapper-bearing Gardenia.
(Cinchonaceæ ) A stove shrub ; growing four feet high ; with pale buff flowers; appearing in spring ; A native of Sierra Leone ; increased by cuttings; grown iu lcul moald, loam and said, Flore des serres, pi.
We have recently noticed several of the splendid species of Gardenia which have been introduced ; and the present plant is another from the same source; it has exquisite large pale buff flowers, with a very curiously formed suigma, which has somewhat the appearance of a bud; the foliage is also handsome, deep green, and rich. It is a noble acquisition, and, with the G. Stanleydna and Devoniàna, should be introduced into every fine collection of plants. Culture the same as for the other species. (Flore des Serres, July.)
Sir. W. J. Hooker remarks that the species described by Dr. Lindley as G. Devoniàna is the Randia longiflòra of Salisbury.
38. Sisyri’NCHIUM LONGISTYLUM Nob. Long-styled Sisyrin
chium. (Iridacèæ.) A greenhouse bulb; growing six or eight inches high ; with yellow flowers ; appearing in spring; a native of Chili ; increased by offsets ; cultivated in loam, leaf mould, and sand. Flore des Serres, 1847, pl. 255
A very pretty species, with somewhat the appearance of an Ixia in its flowers, and the peculiar imbricated habit of the Witsènia corymbosa in its foliage. It was introduced into the collection of Van Houtte in 1845, and, from its free blooming, handsome habit, and golden flowers, must prove one of the greatest ornaments of our gardens. It is a halfhardy perennial, and should be wintered in the cold house. Loam, leaf mould and sand make a suitable compost. It flowers freely. (Flore des Serres, Aug.)
39. DIPLADENIA RO`SA-CAMPE'STRIS Nob. The Rose-colored
Field Dipladenia. (Apocynaceae.)
The Dipladenias are beautiful climbing plants, adapted to stove culture, the greenhouse being scarcely warm anoi gh to keep them in good health, growing a few feet high, and producing numerous bell-shaped flowers of various shades. The present species is especially beautiful, and has received the poetical name of the Rose des Champs. "Nothing can be more beautiful or more elegant in color, than the large flowers of this species, with their ample petals, of a soft rose, satiny beneath, and spotted in the centre with deep rose." l'he leaves are opposite, oval, distinctly russeted, and velvety, and the flowers appear in clusters on the ends of the shoots. It is a very fine plant, and merits a place wherever there is a suitable one to bloom it well. (Flore des Serres, Aug.)
40. DICE'NTRA SPECTA'BILIS Nob. Elegant Dicentra. (Fu
mariacec.) A hardy perennial ; with purple Rowers ; appearing in summer; a native of China , increased by division of the root; cultivated in any good soil. Flore des Serres, 1647, pl. 258.
“ Beyond all comparison the handsomest of all the Fumeworts which have been introduced. It was introduced to England by Mr. Fortune, who brought it home with him from China. In good health, its stems grow nearly two feet high, and have three or four axillary racemes of beautiful flowers, each raceme from four to six inches long. The flowers are full an inch long, and nearly three quarters of an inch wide. Mr. Fortune states that it is one of those plants of which the Chinese mandarins are passionately fond, and cultivate extensively in their small gardens. He found it in the Garden of the Grotto, (in Chusan,) growing on artificial rockwork with the beautiful Weigėlia rosea. Its great resemblance is to the old Fumària formosa, (now Dicéntra,) but is far finer in every way. It is a very great acquisition, and, with the Anemone japónica, and other of Mr. Fortune's plants, will probably prove quite hardy. (Flore des Serres, Aug.)
41. ACHI’MENES CUPREA TA Hook. Coppery-leaved Achimenes.
(Gesnerrore ) A greer house plant ; pri wing two fee 1 hi. h with chilei Rowers : 911enrirg all runner: a Dative of New Grenaditi increased by off-els and culti.s; cul ivaled ii turfy peat, leaf mould, and sand. Flore des series, 1847, pl. 2611,
A new and interesting species of this now quite extensive family, containing upwards of a dozen species. The leaves are of a dull, coppery hue above, and a rosy purple huc beneath, and the flowers, which are small, and of a rich scarlet, have a pretty effect upon the sombre-colored foliage. It was found in New (irenada, and the seeds sent to the Kew Garden in 1840), and the plants flowered m April last. It requires the same treatment as the other species and, from the peeniliar rambling habit of the plant, rooting, as it does, at every joint, and its bright fowers, it will be a desirable species. (Flore des Serres, Aug.)
42. FORSYTHJA VIRIDI'SSIMA Lindl. Dark-green leaved For
sythia. (Oleirer.) A hurdy shrub; growing six to ten feet hiuh ; with yellow flowerx; an earing in spriis ; & bative of China ; increased by layers ; cultivated in any stod soil Flore des Serres, 1847, pl. 261.
This is a new and beautiful shrub, brought home by Mr Fortune, on his return from China, who has given the following account of it in the Journal of the London Horticuliwal 10ciety:-"It is a deciduous shrub, with very dark green leaves, which are prettily serrated at the margin It grows cight 10 ten feet high, in the north of China, and sheds its leaves in autumn. It then remains dormant, like any deciduous shrubs of Europe, but is remarkable for the unter of large proninent buds which are scattered along the young stenus produced the summer before. Early iu spring, these buds, which are flower buds, gradually unfold themselves, and present a profusion of bright yellow blossoms all over the shrub, which s highly ornamental "
Mr. Fortune found it growing at Chiusan, in the sane çare den with Weigėlia rosea owned by a Chinese mandarm, and called the “Grotto Garden," by the English. It is a great favorite, and is grown in all the gardens of the rich in the norih of China. He afterwards found it growing wild in the nontain of Chekiang, when he thought it even more oruaniental, in its natural state among the hedges, than when cultivated in the fairy gardens of the mandarins.
M. Van Houtte states that "this remarkable plant is destined to be one of the greatest ornaments of our gardens, de. veloping its flowers in the earliest days of spring, at the same period as Chimonáuthus fràgrans, Calycanthus flóridus, Pyrus japonica, &c., among which its golden yellow flowers contrast very nreutily, or in the middle of a cluster of ornamental trees and shrubs, either deciduous or evergreen." It is easily multiplied by cuttings or layers. (Flore des Serres, Aug.)

43. GLOXINIAS Hybrid varieties
2 Teichleri. 3. Comtesse Leopolijine Thun. 4. Com lesse Inza Thun. 5. Comtesse (Carline Thun Flore des serres, 187, p. 205
These are all exquisite hybrids of the gloxinia, surpassing, with the exception of G. Cartoni, any that have yet been raised. G. Teichleri we have already described, (p. 403.) No. 1, is similar to Cartoni; 3, white, with a claret centre; 4, white, with a blue centre, and 5, white, with crimson centre. M. Van Houtte has brcome the proprietor of these, which were raised by Mr. Joscht, gardever to the Comte Thun, of Bohemia, and they will soon find their way into collections.
Spring Bulbs.—Having made a selection from the bulbs advertised in a good catalogue, according 10 nis lastes and pecuniary means, the amaieur should immediately decide what 10 do with them. In their arrangement, reference should be constantly made to the season when they bloom, ihat the position in the garden may be chosen which is best adapted to their display. Many of them come in flower at a uime when the whole garden is not readily accessible, especially if there is much grass. To place flowers in situations seldom visiied, or which cannot be reached without getting damp in the feet, or without treading over gravel walks which recent frosts may have disturbed, would be a useless expenditure of time and money. The eye, therefore, should glance round the premises, and the bulbs be apportioned to those parts nearest the dwellmg-house, which frusts and rams are least likely to make unapproachable.
By detailing his own practice, the writer conceives he may best promote the interests of his readers, and he will therefore tell what he means to do in relation to his own garden in the department of bulb-planting. A road passes up to his house, bounded on one side by a lawn, within a foot of the edge of which are circular beds, about two feet across, and a yard distint from each other. These are now occupied with dahlias and scarlet pelargoniums alternately, and consequently may soon be expected to be vacant, and they are then destined to be occupied by bulbs. It is proposed to remove the soil to the depth of eight inches, and then to dig into the lower stratum a good quantity of leaf-mould and road-grit, which has previously been mixed togeiher, and, for the greater part of the past year, has been in a decomposed state. This being well incorporated with the soil of the beds, the surface of each must be smoothed, and the bulbs placed upon it, a little pressure biing used with each, to settle the disturbed mould, which would otherwise be 100 hollow. Round the bed put two rows of crocuses not more than one mch from each other; then six hyacinths spread equally over the remaining portion, filling up the vacant spaces with early tulips. Each bed of this size will thus contain about seveniy.iwo crocuses, six hyacinths, and a dozen early tulips. The taste of each gardener can regulate the colors of these various kinds of flowers, as there is room for great diversily. The hyacinths may be all different, or mixed, or all alike in each bed; and the crocuses may be mixed, or of une kind. If a number of small beds are logether, a good effect would be produced by having one color in a bed, the contrasis being furnished by the beds themselves. As there Day be innumerable combinations of colors, each amateur can consult his own pleasure in the matter.
When the beds are thus filled, a little leaf mould and sand may be placed over them, and the soil taken out should then be carefully replaced, if of good quality ; but, if it is gravelly and heavy, it had better be all removed at once, and a light friable loam be put instead of it. All is then completed, and we must wait vill spring does its work, and brings the flowers above the soil. The crocuses will appear first, then the tulips, then the hyacinths, keeping up a succession from February 10 way. By the beginning of June, all will be ready for removal, to make way for summer fowers. The interest attached to such beds will be very great indeed, fully repaying the cultivator for all his expense and toil, and giving a beauty of no common kind to the garden at a season generally deficient of flowers.
Of course, the gardener can place his bulbs where he pleases ; and this illustration is only given as a general guide. The principles of management will apply in every case, an adaptation being adopied according to the size and position of the grounds.—(Gard Chron. 1847, p. 637.)
Bulbs in Pots.-A correspondent of the Chronicle requesis some information respecting the growih of bulbs in pois, in the practice of which he confesses he has himself failed. The subject was glanced at in an article on hyacinths, in No. 36 of this paper, to which the reader is again referred. However, as the subject is capable of being more minutely treated, and is extremely interesting at this season, we shall endeavor to give those explicit details which will satisfy the inquiries of the least instrucied in these matters In these papers we write for the tyro and not for the advanced gar. dener, and therefore repetitions must uccasionaliy be excused.
