A pretty little herbaceous plant, seldom seen in cultiva- tion. It inhabits various parts of North America, from Texas as far north as Pennsylvania, trailing over naked rocks, its favourite place of resort.

In our gardens it is treated as a greenhouse plant, and then it forms neat patches of lively purple flowers. It is, how- ever, rather rare.

Our drawing was made in 1841, in the garden of the Horticultural Society, where it had been raised from seeds received from Mr. Otto of Berlin.

. . A bulbous plant from Lima, whence it was sent by John Maclean, Esq. to the Horticultural Society, with whom it flowered in February 1812.

The yellow flowers, and their general appearance, remind one of the yellow Calostemma of New Holland ; only they are larger.

It is essentially distinguished from the other known species by its broad leaves, depressed bulbs, and the intermediate teeth of the cup being obtuse and undivided.

The plant flowered in a cool stove, where it had been kept "warm and moist while growing, but cooler and drier while at rest. T

It is among the prettiest of the Western -American bulbs ; . but is at present extremely rare.

O. eitrosmum (Lindl. Bot. Reg. 1842. misc. 68.) ; pseudobulbis subrotundis compressis leevibus monophyllis, folio oblongo-ligulato obtuso racemo paulo breviore, sepalis oblongis obtusis petalisque conformibus subae- qualibus, labello unguiculato reniformi basi bituberculato, column alis lateralibus subtruncatis dorsaliq. rotundato denticulatis.

Although such plants as this seem as if they weakened the genus Odontoglossum, on account of their similarity in habit to Oncidium, yet in truth they rather confirm that genus by showing that although the appearance of Oncidium may be assumed, yet the main points of structure remain unaffected. One of the most important of these points is the partial paral- lelism of the base of the labellum with the column, and the presence of a pair of parallel raised plates at that part. This occurs in the original Odontoglossum, and runs through all the numerous species published and unpublished with which I am acquainted ; and it does not occur in any Onci- dium. |

While however, notwithstanding its habit, this Odonto- glossum citrosmum confirms, rather than diminishes, the pro- priety of separating Odontoglossum from Oncidium; it has a peculiarity of its own, which may possibly suggest to some minds the propriety of forming it and such plants as O. brevi- folium and pulchellum into a separate genus, characterized by the presence of a toothed wing or membrane at the back of the anther; and the similarity of these plants in habit might seem to justify the measure. In that case the generic name of Trymentum might be taken for them. I do not however

at present see the necessity of regarding them as more than a section of Odontoglossum. |

It was imported by George Barker, Esq., of Birmingham, from Mexico, and given to Thomas Brocklehurst, Esq., of the Fence near Macclesfield, by whose gardener it was exhi- bited at one of the great meetings of the Horticultural Society at Chiswick in 1842. It has large snow-white and rose-coloured flowers, of great beauty, exhaling a delicate smell of lemons. |

Although this cannot be said to rival such species as Hovea pungens or Celsi in the brightness of its colours, it is by no means unattractive, when well contrasted with plants whose colours are not bright enough to kill it. It belongs moreover to a set of greenhouse shrubs of easy cultivation and small size, which are well adapted for decorating the shelves of the conservatory.

It is a native of the Swan River colony, whence the seeds were obtained by Capt. James Mangles, R.N. It first flowered in the garden of Robert Mangles, Esg. of Sunning Hill.

Among the species of this genus from the East coast of New Holland is one, called Hovea ramulosa by Allan Cun- ningham, which approaches this very much in several respects. But that species has solitary axillary flowers, more obtuse . leaves, and a still more shaggy surface. As it does not seem

to have yet found its way into books, I may as well take the present opportunity of stating its characters.

VAN HOUTTE'S PHLOX.

M

Garden Variety.

For a knowledge of this remarkable plant we are indebted to M. Louis van Houtte, nurseryman of Ghent, who sent it to us in October last, in full flower; but without any account of. its origin. ©

It is a variety of remarkable beauty, looking as if P. sua- veolens had been crossed with P. caroliniana, leaving on a ` white ground a crimson evidence of its paternity. The ap- pearance of the plant is beautiful, far beyond any thing yet seen in the genus Phlox ; and we were almost going to say, beyond any thing among the hardy perennials in cultivation.

An approach to it was exhibited last year by Mr. Mount- Joy, nurseryman of Ealing, but it was only an approach, with a much paler stain on the corolla. That, however, was very pretty ; and well worth the acguisition of the lovers of gay flowers.

Probably there is no plant among all the species of Dendrobium now known to our gardens which is more deli- cately beautiful than this. Its colours too are so singular as on that account alone to render it an object of much interest ; for here we have the cyanie and xanthic tints in one and the same flower. We are always prepared to find red spots on a yellow ground, or vice versà, but it is a most unusual thing to find clear pure violet on petals the whole remainder of whose tint is yellow. In this plant, however, the combination oc-

curs, producing a very gay and unexpected effect.

It was sent from Ceylon, to His Grace the Duke of Nor- thumberland, by Mr. Nightingale, and flowered at Sion in August last. It has pendulous stems like those of D. Pierardi, but of a delicate purple when young; the leaves too are stained underneath and at the edges with the same colour. The flowers are as large as those of D. aggregatum, of a clear fawn colour, with the tips of the segments and lip stained with a deep rich violet. There is moreover a scarlet

spot in the middle of the lip.

Fig. 1. represents the outline of the lip of this plant. Fig. 2. shows the form of what I take to be a variety, larger,

and having the middle scarlet spot, but destitute of the violet tips. This is not distinguishable from the other in foliage, nor in any other way than in the manner now indicated.

Both species have a strong downy tooth near the base of the lip, parallel with the surface and directed towards the foot of the column.

A. umbellatus. Bot. Reg. l. c. e Var. maximus ; foliis latioribus, floribus multò majoribus.

. Since the days when the commerce of the Dutch revealed to Europe the vegetable riches of the Cape of Good Hope, and filled the gardens of Holland with crowds of unknown forms, the African Blue-Lily, or asit was formerly called the African tuberous Hyacinth, has been a favourite object of cultivation. It has now, however, become common, and, discarded from the gardens of the great, to their own loss, has sought refuge with humbler cultivators, with whom it still is, and we trust always will be, a cherished favourite.

We do not find in such authors as we have an opportunity of consulting, any precise information as to the favourite loca- lities of Agapanthus. Mr. Harvey says, that one species is very common on the sides of Table Mountain, but which species, or what the kind of places it is found in, he does not state.

‘With regard to the species, these are so little understood that, although this may well be distinct from A. umbellatus, we have no materials for defining it, and therefore we leave it to our successors; possibly it may be the A. multiflorus of Willdenow. Mr. Harvey says there are several species in the Cape Colony; it would be well worth any one’s while to collect and compare them, so as to settle the distinctions that exist.

The accompanying drawing was made in the nursery of February, 1843. D

Mr. Groom, of Clapham Rise, in September last. It is a beautiful plant.

Those who wish to grow these African Blue-Lilies in the ` best manner, should proceed with them thus :— About the end of February the plants should be fresh potted, in a mixture of rich loam, and well decomposed leaf-mould, or well rotted dung, and placed in a warm part of the greenhouse, where they will soon begin to grow freely. They will then require to be abundantly supplied with water, and about the end of May should be removed to the open air, if it is intended that they should flower out of doors, The pots should be placed in a sheltered situation, in large pans filled with water, so that one-third of the pots is immersed ; or the pots may be placed by the side of a pond, and the plants treated as subaquatic, in which situation they will flower freely during the summer. If they are retained in the greenhouse during the blooming season, they must have plenty of air and water, or they will become weak, and lose that beautiful deep blue colour, which . so much distinguishes them.

When they have done flowering, in the autumn, they should be gradually dried, by withholding water, and finally, when the soil in the pots has become tolerably dry, and there is danger of frost, the pots should be removed for the winter, either into a cold pit, or under the stage of the green- house. Or they may be placed in a cellar, but then they must be kept very dry, and should be removed from such a situa- tion as soon as they shew signs of vegetation.

These plants will also force freely, if well supplied with moisture and bottom heat; but in that case the flowers be- come very pale. They are easily increased by dividing the old plant when in a dormant state. They seldom require shifting when once established, if supplied once or twice, © during the growing season, with a little liguid manure.

This is one of those beautiful little Myrtaceous plants . peculiar to the South-west of New Holland, which might be easily mistaken for small Almond or Peach bushes, so much are the flowers like them, and so seldom do we find bright rosy blossoms among the Myrtles.

It is a native of the Swan River Colony, and bas been raised by Messrs. Lucombe, Pince & Co. of Exeter. The ieaves when bruised smell very agreeably of lemon.

It is a greenhouse plant, and requires to be potted in a compost consisting of loam and heath-mould, with a small ortion of silver sand. The pot must be well drained, so as to allow all noxious matter to pass off. Water should be freely

Fig. 1. represents a flower-bud, with the bracts at its base. Fig. 2. shews a section of the flower, made perpendi- cularly through the ovary; the partition that divides the ovary into two cells, is seen to rise only half the height of the cavity, and to bear an ovule and half on each side, one and a half more being removed from each side; hence the ovary is half bilocular, with three ovules in each cavity, two inserted near the apex on each side, and one in the middle near the base; this is better shewn in fig. 3. which is a trans- verse section near the apex of the cavity of the ovary.

C. planiceps ; sepalis petalisque ovatis conniventibus, labello carnoso galeato rotundato compresso apiculato indiviso margine serrato.

Notwithstanding our unwillingness to add to the doubtful species of this strange and changeable genus we can hardly hesitate about regarding this as new. It is true that its habit is that of C. maculatum, tridentatum, and semiapertum, from the second of which it differs in its serrated lip, from the first and last in its lip not having the edges incurved, and from all in the singular truncate form of this helmet-shaped organ, which is flattened from front to back and not laterally.

It is a native of the Spanish Main, whence it was im- ported by Messrs. Loddiges, with whom it flowered in June 1841. It is the No. 934 of their catalogue.

It may be cultivated in a similar way to the other species; by being potted in mossy turf and potsherds mixed with some small pieces of wood. Like other fleshy-stemmed Orchidacez, this requires three seasons, namely, that of growth, of flower- ing, and of rest. In spring, while in a vigorous state, plenty of water and a humid atmosphere is requisite, at a tempera- ture not less than 70° at night, nor yet above 80° in day, and shaded during sunny weather. As the flowering season advances, the water should be diminished gradually ; and in winter, when the plant is in a dormant state, withheld alto- gether for a few weeks, and the temperature not allowed to rise above 60° or to fall below 50°.

Although the limits of the genera of the Bromeliaceous order are much better defined than they were a few years ago, there are no doubt some distinct groups still concealed among the little known species crowded together under the name of Tillandsia. The present instance we conceive to be one of them.

Although referred to Tillandsia this has neither a supe- rior ovary, nor the scaleless petals that are essential to that genus. On the contrary, it evidently belongs to Endlicher’s second section of the order, at present consisting of Pitcairnia and Brocchinia only. From the latter it differs in its revolute scaled petals, and distinct filaments; from the latter in its distinct sepals, and regular revolute petals. From both its large channelled coloured bracts distinguish it at first sight.

This is an extremely pretty stove plant, for which we are indebted to C. B. Warner, Esg. It is said by Sir W. Hooker

to be a native of the neighbourhood of Rio Janeiro.

Fig. 1. represents a petal, with the two scales at its base; and it also shews how one of the stamens is inserted into the very base of the petal, between the scales, while the petals themselves are united by the stamens that are intermediate to them. Fig. 2. shews a section of one of the scales, and indicates that they are adherent to the petals for more than half their length. Fig. 3. is a section of the ovary. |

In cultivation this requires to be potted in leaf mould, with a quantity of potsherds for drainage. Plenty of water should be given during the summer months, but sparingly in winter. Or it may be grown suspended in a wire basket, like an Orchidaceous plant. It is propagated by suckers.

With the exception of the short notice in our work, last

year, in the place above quoted, we find no account of this

lant, our figure of which was made in the nursery of Messrs, ftolliesoris, of Tooting, in June last,

It is said to be a Japanese species, and although very infe- rior in point of a to L. speciosum, Thunbergianum, and their varieties, is a plant that well deserves to be cultivated.

It is a handsome frame or half-hardy bulb, growing best wben planted out in a cold pit, where the bulbs can be kept dry during winter. s

It should be planted in the pit in autumn, or very early in spring, and when once established should not be afterwards disturbed, for: all these plants suffer injury by removal, in consequence of the loss of their tender perennial fibres, and by the bulbs becoming dry.

"Whether planted or potted, the bulbs should be placed

‚rather deep, because they make fibres above the bulb as well

as below it; and when they must be shifted it should be done

while they are dormant. The greatest care should be taken

during the operation of turning them out of the pots, and E

removing the crocks from amongst the fibres; without shaking off much of the soil. They should be then fresh potted in a mixture of sandy peat, loam, and a small portion of well rotted dung or leafmould, with ample drainage. They should after- wards be kept dry till they begin to grow, when water should be given, but rather sparingly at first. Much damage is done to fresh potted bulbs by keeping them damp directly after fresh potting, and while in a state of rest.

It is easily increased by separating the scales of which the old bulb is composed, which are to be placed in pots filled with very sandy soil and exposed to a gentle heat. They will be two or three years before they flower.

The plant grows from one to four feet high, according to the strength or size of the bulbs and flowers, from July to September, according to the manner in which it is treated,

Among the numerous fine things found in Guatemala by Mr. Skinner, there are not many which are more deserving of cultivation than this plant, which has so much the habit of O. Cavendishianum as to seem a mere variety of it, although in reality quite a distinct species. It was also met with by Mr. Hartweg. The flowers are fully two inches in diameter, which is four times the size of O. Cavendishianum ; they . appear in a dwarf erect raceme, not panicle; they are of a rich yellow, with the sepals and petals bordered with cinnamon colour; the labellum has two very small lateral lobes, and for its crest it has a pair of distinct tubercles, the posterior double, the anterior 3-lobed, and the two separated by a con- siderable space. The flowers are moreover slightly scented, which is not the case with O. Cavendishianum. Many plants are doubtless in the country; but no one has succeeded in flowering them except Mr. Bateman, who sent a fine specimen to a late meeting of the Horticultural Society,

which it indicates the unusual form of the narrow incurved

wings of the column, and a thickening of the margin of the lip near its base.

It is a stove plant, and requires to be grown in a mixture of turfy peat and potsherds ; so that the whole may be effi- ciently drained. A smaller pot, inverted in the one in which it is potted, allows the warmth to rise through the soil, and makes the whole lighter than when it is drained at the bottom: with potsherds. It may also be grown suspended from the rafters of the house like other air plants, provided it is kept moist enough during the growing season. Like all these plants it requires a humid atmosphere, a liberal supply of water when growing, and partial shade during bright sun- shine in summer. A night temperature of 60” in winter and 70° in summer will be amply sufficient for its growth.

P. gracilis. Don fide Steudel.

This pretty twining plant is a native of Buenos Ayres, or rather of Tucuman, whence its seeds were originally sent to the Glasgow and Glasnevin Botanic Gardens by Mr. Tweedie. It varies a good deal in the colour of its flowers and in the quantity of down that covers it; in wild specimens it soon becomes woolly; but these differences do not appear to be - specific. In respect of colour, the variety now represented and that with pale yellow flowers, in the Botanical Magazine, may be taken as the two extremes.

The Philibertia gracilis of the Gardens has been referred to this species by Steudel, and with reason. It is clearly no more than a variety of P. grandiflora.

* J.C. Philibert, after whom this genus has been named, was the author of an Introduction to Botany published in 1799, of a Botanical Dic- tionary dated 1802, and of some other elementary books.

P. Gilliesii, a species from Mendoza, not yet that we know of in cultivation, is a much smaller plant, either smooth, or with an exceedingly short close down, and with the base of the leaves almost truncated, instead of being deeply heart- shaped.

The accompanying drawing was made in the Nursery of . Messrs. Rollissons, in August 1838. The same individual had flowers of different colours, all however sweet-scented.

A pretty slender greenhouse creeper, well adapted for training up the rafters of the greenhouse, or over ornamental trellis-work affixed to a pot.

This, like most other plants belonging to the order Ascle- piadacem, succeeds best when cultivated in friable loam and sand; and if the loam is rather poor, a little leaf-mould may be added. The soil when used should not be sifted, but merely broken fine and mixed with the hand. The pots should be well drained, as the plant requires to be kept nearly dry during the season of rest.

When the plants begin to grow in the spring, they should be fresh potted and cut back to the previous growth; being afterwards placed in a gentle bottom heat for a few weeks, and having the supply of water increased. During the whole period of their progress, they should be kept in a rather moist atmosphere, as they are subject to the attacks of the red spider.

This plant is easily increased by cuttings treated in the

ordinary way, and it flowers freely during the summer and autumn.

When it has done flowering, it should be allowed to rest, by gradually withholding water until the soil in the pots be- comes tolerably dry. The pots should then be kept in the warmest and driest part of the greenhouse during the winter.

I. stachyodes ; frutescens, ramis pubescentibus angulatis, foliis utrinque dense pubescentibus 18-22-jugis: foliolis linearibus acutis margine re- curvis, racemis erectis axillaribus sessilibus foliis subaequalibus, bracteis pilosis alabastris longioribus, calycibus cyathiformibus, ovario 7-ovulato.

Among the crowd of species now found in the genus In- digofera it is not easy to say whether this is new or not; we believe however that 1t may be so considered, although we are in ignorance of its fruit.

Its seeds were collected in Bhotan, one of the independent states in the North-east of India, by W. Griffith, Esq., at the height of 4000 feet above the sea, and sent to Richard Hors- man Solly, Esq., by whom they were presented to the Horti- cultural Society. It flowered 1n the Gardens at Chiswick, in September 1840.

Fig. 1. represents the calyx and stamens ; fig. 2. the ovary of this species.

A handsome hardy greenhouse shrub, growing readily in a rich open soil, chiefly composed of sandy loam, with a little

' leaf-mould.

It is easily increased by cuttings of the young wood, par- tially matured at the base, placed in sand, with a little bottom heat. 'The plant, when in good health, flowers during a greater part of the summer.

‘From among some Abyssinian seeds sent to the Horticul- tural Society, from Paris, has been raised a plant of a genus of Labiatz, which does not appear to be described. It is a shrub with downy stems, ovate-lanceolate, serrated, slightly petio- lated leaves, and verticillasters of beautiful flowers arranged in short spikes. The calyx has a broad upper lip, like that of an Ocymum, the lower lip is deep, truncate, bordered with a close fringe of white hairs, and terminated in front by a pair of feeble teeth. The corolla is large, white, with lilac veins, and nearly an inch long. ‘The upper lip is 3-lobed, with the middle lobe split at the point, and the points of all rolled back ; the lower lip is of about the same length, oblong and , concave. The stamens are four, declinate, bright violet, and

about an inch long. The anthers are ovate, with a distinet pair of lobes attached to rather a convex connective. The ovary is almost entirely buried in a fleshy 4-lobed disk ; the style is long, violet, follows the direction of the stamens, and ends in a stigma with two equal subulate lobes. Both the style and filaments are twisted spirally before the corolla expands.”

This plant evidently belongs to the Ocymoideous La- biate plants, but does not agree with any of the published

genera. Its singular calyx seems by itself to mark it suffi-

ciently, independently of which the plant differs from Plectran- thus and its allies in the egual size of the two lips of the corolla ; and from Ocymum and its allies in the long declinate stamens, distinctly bilabiate corolla, and whole habit.”

Such was the view we took of this plant some months ago. Since that time it has been suggested to us by Mr. Bentham that the plant is very near Ocymum filamentosum, and upon turning to the descriptions of that species we find them so much alike, that we cannot doubt their belonging to the same genus if not the same species. It is not however quite certain as to the latter point, because Mr. Bentham describes his plant with appendages to the longer pair of anthers, of which appendages we have no trace in our plant.

Be this however as it may, we regard Becium as distinet from Ocymum for the reasons formerly given.

Fig. 1. represents the remarkable calyx ; Qa portion of the corolla with the 4 stamens; 3. the pistil, having its ovary plunged in a lobed disk. |

It is a half-hardy plant; but, coming from a warmer climate than many other kinds which we commonly find in greenhouses, it will not bear such a great degree of cold in winter. It will flower freely in the autumn and winter in a temperature of from 40° to 45°, and is adapted for conserva- tories which are kept about this temperature. When potted . in any light common soil, it grows freely and is very easily multiplied by cuttings.

A greenhouse shrub of some beauty, imported from Swan River by Messrs. Lowe and Co. of Clapton, with whom it

flowered in October last. G

It differs in nothing from the wild specimens in our pos- session, except that the flowers are less numerous in the axils, and therefore do not present an appearance to justify the name of capitate so much as they do.

Fig. 1. represents the ovary, with the side removed to shew the three pairs of ovules.

It should be potted in light heath soil, mixed with a little leaf-mould and sand ; the pot must be efliciently drained. When grown in the greenhouse, and subject to the same treatment as the generality of these plants, it succeeds admi- rably, and remains in bloom for several months in summer and autumn. Like all plants of this kind, it requires an abundant supply of water during the growing season ; but

that quantity must be reduced at other times. It is easily

multiplied by cuttings and seeds.
