ATTALEA(fromattalus, magnificent; referring to the beauty of the genus). ORD.Palmaceæ. A genus of handsome stove palm trees, distinguished from other genera in having the pinnæ arranged vertically, and not horizontally. The leaves spring up almost perpendicularly at the base, but in the upper part arch over. The pinnæ stand at right angles to the rachis—which is very narrow in proportion to its thickness—and while those of the lower side of the arch hang straight down, those of the upper side point straight up. They thrive well in a mixture of peat and loam in equal quantities, and enjoy a copious supply of water. Summer temperature, 65deg. to 80deg.; winter, 55deg. to 60deg. All the species are robust trees; but, although several have been introduced, few appear to be generally grown.

FIG. 192. FRUITINGBRANCHOFLONGAUBERGINE.

AUBERGINE, orEGG PLANT(Solanum melongena, varietyovigerum). These plants, besides being useful for culinary purposes, are very ornamental, and present an attractive appearance on walls or trellises, or in the flower garden; and, as they do well in any ordinary rich garden soil, if the position is warm, they give a good variation to the general run of plants used for decorative effects. The Black-fruited kind is particularly suited for this purpose. Sow the seeds in a gentle heat, in the middle of April. As soon as the seedlings are large enough to handle, prick off into 4in. pots, replacing in heat till they root out freely. Gradually harden off by June, and then transfer to the positions where they are to grow. Let the plants be at least 2ft. apart, and place a strong stick to each one to support the fruit when it comes. For trellises, select the more moderate-sized varieties. In hot, dry weather, the application of liberal supplies of liquid manure tends to increase the size of the fruit, and also to make the foliage more vigorous and handsome. Where very large fruit are needed for show or other purposes, it is well to remove all but the best one on the plant, and, by careful feeding with liquid manure, specimens of from 10lb. to 12lb. weight can be had. The foliage should not be pinched, as this would prevent the free swelling of the fruit. Aubergines are not so much grown in England for culinary purposes as in France and Italy, where they are largely used in stews and soups. The following are the most desirable varieties: New York Purple, the largest kind grown, and although not as ornamental as the next, is quite as useful; Black-fruited, large black fruit, with blackish violet leaves; and White-fruited, the sort most generally cultivated. See Figs. 191 and 192.

AUBRIETIA(named after M. Aubriet, a famous French botanical draughtsman). ORD.Cruciferæ. A small genus of hardy evergreen trailers. Racemes opposite the leaves, and terminal, lax, few-flowered. Leaves ovate or oblong, entire or angularly toothed, hairy. They make excellent rock plants, and will thrive in a deep rich loam anywhere, excepting under the shelter of trees. Cuttings struck, or seeds sown, during April or May generally make fine, dense, cushion-like growths, if transplanted on to a somewhat cool or shaded border, and carefully lifted in the autumn; the cuttings are best "drawn," or grown until they are soft, in a frame before they are removed. Where a stock of old plants exist, layer the long slender branches any time after flowering, and cover with a mixture of sand and leaf soil; they will then root freely and establish themselves in time for spring blooming, for which purpose, when grownen masse, they are most useful. After flowering, they may be divided and transplanted.

AUCUBA(the Japanese name of the shrub). ORD.Cornaceæ. A genus of hardy evergreen shrubs, thriving better than any other in the smoky atmosphere of dense cities. They grow in ordinary well-drained garden soil, and require no special culture. If grown in pots, they should be planted firmly in rather sandy yellow loam, with plenty of drainage. They should not be allowed too large pots, or an unfruitful growth is likely to result. During the growing season, an abundance of water is needed, which must be lessened when the plants are fully developed. If cultivated in the greenhouse or conservatory, they should be plunged out of doors during summer. To insure a good supply of the very ornamental berries, which are produced on the female plant, careful fertilising is necessary. The time for applying the pollen is when the pistil exudes a slightly gummy substance, and otherwise shows signs of maturity. When it happens, as is sometimes the case, that the male blooms are open and the pollen mature before the female blooms are ready, the pollen should be collected on a dry camel-hair pencil, transferred to a piece of glass, and covered over by another piece, both of which must also be dry. It may be applied afterwards when wanted, as it retains its power for some weeks. Propagated by cuttings, inserted in any light sandy soil, with or without a covering, in spring or autumn; or readily increased from seeds, sown as soon as ripe.

Japan, 1783. The numerous varieties, both of the male and female forms, among which will be found many of great beauty, all differ, more or less, in the variegation of their leaves. They are in very general cultivation, and nearly every nurseryman has an assortment. Among the best of them are the following:albo-variegata,aurea,bicolor,latimaculata,limbata,longifolia,macrophylla,ovata,pygmæa, andpygmæa sulphurea.

AURANTIACEÆ.An order of trees or shrubs, including the Orange and Lemon trees. Flowers fragrant. Fruit fleshy, edible. Leaves alternate, articulated above the stem, filled with transparent oil cysts, giving them a dotted appearance. Well-known genera areCitrusandLimonia.

AURICULA(Primula Auricula). This favourite spring flower (see Fig. 195) was, at one time, almost universally cultivated, but has of late years fallen into much neglect; it is now, however, happily regaining enthusiastic admirers. Although its culture is not nearly so difficult as is generally understood, a few special items of treatment are nevertheless necessary to grow it successfully.

FIG. 195. A VARIETYOFPRIMULAAURICULA.

Framesfor the reception of Auriculas should be prepared, with a good bottom drainage, and an inside staging, similar to the back stage of a lean-to greenhouse, arranged as near the glass as possible. If the frames are about 4ft. wide, they will be very convenient; 1ft. deep in the front, and about 3ft. at the back. This will allow for a good stage arrangement. Of course, it is not necessary to construct an expensive staging, as common boards can be laid upon pots of various heights, the same results being practically secured. These frames should face north from May to October, and south in winter, during which latter time it will be necessary to well cover the sides with straw or brake. When frosty, the lights must also be mated; but, unless there is absolute fear of frost, the glass should not be covered, as the more light the plants receive the better. On all suitable occasions, both during summer and winter, air must be freely admitted, and a good look-out kept during showery weather; hence it may be necessary to tilt the lights with blocks rather than remove them entirely. The latter plan should be adopted whenever practicable, especially during early spring, and after they are well established in their fresh pots in summer. This will greatly assist to ripen the crown, and produce hard, stout foliage, which will endure the winter much better than if grown with less air. Many cultivators prefer small span or lean-to houses to frames; and it must be admitted that these are better, more convenient, and in every way more beneficial. Simple, inexpensive structures, no higher than is absolutely necessary for convenience, with top and side ventilation, will meet all requirements; and if a 2in. hot-water pipe is arranged next the eaves inside, it will be a decided advantage during very severe weather.

Soil.The best compost that can be prepared for Auriculas is as follows: Four parts good fibrous loam, one part well-rotted cow manure, one part good leaf soil, and one part coarse river or silver sand, with a little charcoal or pounded oyster-shells added. Carefully mix the whole together before using. The loam should be stored about twelve months previous to being used, and it should be selected from districts with a fine atmosphere; the turf should be cut about 3in. thick. Cow manure that has lain for a year or so, and been subjected to sharp frosts, is most suitable, as insect life, which it very probably contains, is thereby destroyed, and the whole materially sweetened.

Potting.This operation requires to be carefully done as soon after flowering as possible, unless it is desired to save seed, when it must be deferred until the seed is ripened. May and June are the best months for general potting, and whatever the size of the pots used, they should be carefully and thoroughly drained. After a good layer of potsherds, place some charcoal, leaf mould, or spent hops. Many good growers use the last very advantageously. For good flowering plants, 48-sized pots are used, many cultivators preferring glazed pots to the unglazed; but such are not absolutely necessary to ensure success. Before repotting, remove most of the old soil, and with a sharp knife cut off any bruised or cankered portion of roots; the stout tap-root may also be cut away if devoid of fresh rootlets. Do not pot very firmly. Remove the plants to their summer quarters, withholding water for a few days, and keep the frames close. About a week after potting, water may be advantageously given, the plants will then soon resume root-action, and air may be admitted afterwards on all suitable occasions. The collar or neck of the plant must be left well above the surface of the soil.

Wateringis a point that requires careful attention, as neglect in this matter will result in failure. During the growing season, Auriculas require an abundance of water; in fact, they must never be allowed to get dry. In the winter, they must only be watered when they are really dry, especially during a severe season. Care must be taken to avoid watering the leaves, particularly in early spring, as this tends to spoil the effect of the charming farinose foliage. Above all, water must not be allowed to stand in the heart of the plant, as such will inevitably cause incipient decay. Hence it is necessary to keep a sharp lookout for drippings from the glass, and to maintain tightly-glazed frames. On all occasions, decaying leaves must be removed, and especially during winter.

Top-dressing.About the middle or end of February, when the plants commence new growth, the surface soil should be removed about an inch or so deep, and the pots re-filled with a rich compost made up of the following: Two parts of turfy loam, one of rotten cow or hen manure, and one of leaf soil; if a little Standen's Manure is added, the compost will be improved. After this top-dressing, the plants may be watered freely.

Propagation by Offsets.When top-dressing, any offsets with roots should be removed, and as soon after as possible the remaining ones should be taken off, as it is much more desirable to do so early than later on, when repotting; for, when making the first growth, they are the more likely to root better, and stand a greater chance of making good plants before the season is over. Fill well-drained 3in. pots with sandy soil, and arrange about four offsets round the sides; place under a bell glass, or in a close handlight, watering very sparingly so as to prevent them damping off. They will soon establish themselves, after which air may be admitted, and the plants may ultimately be potted off singly. To induce choice varieties to make offsets, the top of the old plant should be removed and treated like the others, when, as a rule, several shoots will be produced, which in due time may be removed. By this means, a nice stock of the rarer kinds may be obtained; whereas, if such a course were not adopted, the rate of increase would be extremely slow.

Flowering.During the flowering period, watering, as already stated, must be carefully attended to, for if the plants are allowed to get dry, the flowers will quickly shrivel. They must also be kept well shaded from sunshine, which quickly destroys the delicate blossoms. As the trusses are developing, particular attention must be givento night protection. It is, perhaps, better to cover every night than to run the risk of exposing the unexpanded flowers to frost, as the effect is very prejudicial; in fact, if subject to frost, smooth even flowers may not be expected.

Seed Saving and Sowing.The only way to obtain new varieties is by seed; hence the value of careful seed-saving will be apparent. Severe discrimination must be exercised in the selection of parents, and the flowers must be very carefully crossed. The anthers should be removed from the pistillate parent, if possible, before expansion, so as to prevent any possibility of self-fertilisation; and, when the stigma is ready, the pollen must be conveyed by means of a small camel's-hair brush, care being taken not to mistake the brushes used in different classes. It has been observed in Auriculas that the issue from crossbred seed favours the pollen more than the pistillate parent; hence the necessity of selecting good pollen parents. It is best to confine hybridisation to separate classes—i.e., cross a Self with a Self, and a Green-edged variety with another of the same class. The importance of selecting the best in each class scarcely needs suggestion, having regard to constitution as well as the quality of the flowers. The seed should be sown as soon as ripe, or early in March, in well-drained pots, filled with sandy soil, which must be well watered previous to sowing. When this operation is completed, the seed must be lightly covered with coarse sand, a sheet of glass placed over the pot, and the latter stood in the hand glass, where the offsets are rooted. Some of the seedlings will appear in a month, but the bulk from that sown when ripe will not be seen until the following spring; while others will germinate even during the ensuing summer. The late comers should be particularly cared for, as they frequently produce the best varieties. When the seedlings are large enough, they must be pricked off in pots of sandy soil; and, when well established, potted off singly into small thumb pots, and afterwards encouraged as judgment suggests. Some growers allow the seedlings to remain in the store pots till they flower, when the best are kept, and those not required disposed of.

Insect Pests.Green fly are often very troublesome, and should be exterminated as speedily as possible, by tobacco fumigation, or by dipping the plants in a solution of Gishurst's Compound, or carefully prepared Fir-tree Oil, all of which are effectual. Many authorities denounce fumigation, while others advocate it. The roots are also attacked by a mealy louse, namedTrama auriculæ, which clusters about the roots and collar of the plants, sucking nutriment therefrom; and although, provided they do not attack the collar, they have no greatly prejudicial effect on the plant, yet it is desirable to exterminate them. The only effectual way of accomplishing this is to remove all soil, and thoroughly cleanse the roots and collar in a solution of soft soap, with a little Fir-tree Oil added. Of course, this is most easily managed when repotting; and, unless the plants are very badly infested, it would not be advisable to run the risk of root washing later in the year.

Classes.Auriculas are now arranged in five classes, four of which constitute what are known as "show or stage Auriculas," while the other is known by the name of "Alpines." Each class is characterised by special points of distinction, which, in the opinion of the strict "florists" school, it is of the utmost importance to observe; and as there is room for systematists in this, as well as in any other branch of floriculture, we will follow the arrangement usually adopted, and describe the distinguishing features of, and enumerate some of the best varieties in, each class, with their raisers' names attached:

Green-edged.Outer edge green, or but sparingly dusted with powder; next, a zone of colour known as the body colour, which varies, the darkest being most esteemed; both edges of this zone should be even, especially the inner one, but there are few flowers perfect in this respect. Next to the body-colour is the paste, which occupies the space between the inner circle of the latter and the throat, this should be pure and dense, with a distinctly circular outline at the throat; the throat and tube should be bright yellow. Of course, this ideal standard has not yet been reached, as there are supposed defects in all or some sections of the flowers at present known.Leading Varieties: ADMIRALNAPIER(Campbell), ALDERMANWISBEY(Headley), APOLLO(Beeston), CHAMPION(Page), COLONELTAYLOR(Leigh), DUKE OFWELLINGTON(Dickson), FREEDOM(Booth), GENERALNEILL(Traill), HIGHLANDBOY(Pollitt), IMPERATOR(Litton), LADYANNWILBRAHAM(Oliver), LORDPALMERSTON(Campbell), LOVELYANN(Oliver), LYCURGUS(Smith), PRINCEOFGREENS(Traill), PRINCEOFWALES(Ashton).Grey-edged.Edge heavily dusted with powder, so as almost to hide the normal green colour; other points same as the Green-edged varieties.Leading varieties: ALEXANDERMEIKLEJOHN(Kay), CHAS.

AVENUES.In forming an Avenue, the plan must neither be tortuous nor of a "tedious sameness," but a gradually winding line should, above all, be obtained, which must in no way interfere with the view from the house. About 12ft. is the width usually allowed for the road, but this depends upon individual taste or idea—this remark applies to planting in double rows, the trees forming a series of triangles, or in single rows. The distance across the road from one row of trees to those opposite should be at least 24ft. The Lime is extensively used for Avenues on account of its regular growth and the shade it affords. The Cedar of Lebanon is one of the best and most suitable evergreens. The Dutch Elm is used because of its rapid growth, and forms one of the best deciduous trees for this purpose. The well-known Horse Chestnut, in sheltered spots, is very ornamental, as is also the Spanish Chestnut; the latter spreads rapidly. Where immediate effect is required, nothing gives more satisfaction than the White Poplar; it grows in a wet soil better than anything else.Deodars, Araucarias, Douglas Pine, the Mexican, Chinese, and Japanese Cypresses, and many others, are eminently suited for Avenue planting. Shrubs and herbaceous plants should be introduced between the trees, and so remove any bareness that may occur.Diervilla rosea, and its variegated form,Aucubas,Rhododendrons,Hypericums, and many others, could be mentioned to serve this purpose. A moderately good soil will be found to answer generally.

AVERRHOA(in honour of Averrhoes, of Cordova, a celebrated Arabian physician, who resided in Spain during the domination of the Moors, about the middle of the twelfth century; he translated Aristotle into Arabic). ORD.Geraniaceæ. Ornamental stove trees, thriving in loam and peat. Half-ripened cuttings will strike in sand, under a hand glass, about April, with bottom heat. The leaves of the first-named species are irritable to the touch.
