Flowers with four spongy, cohering petals. A warm, good soil is most suitable; sow seeds about May in a shady spot. It is a biennial, but in favourable spots is self-sowing, and thus may be treated as a perennial. If placed either against a wall or in the open it is a pretty subject for trailing over a shrub or twiggy branch. From its fragile character, it can only be seen to the best advantage under glass.

Russia, 1818.

ADPRESSED. Brought into close contact with anything without adhering.

ADULT. The full grown of anything. Full grown leaves are termed adult.

ADVENTITIOUS. Developed in an unusual position. Applied to buds, roots, &c.

ADVERSE. Opposite.

ÆCHMEA (from aichme, a point; in reference to the rigid points on the calyces, or flower-envelopes). Including Pironneaua. ORD. Bromeliaceæ. Very handsome stove plants. Flowers scapose, panicled; perianth six-cleft, three outer segments sepaloid, longer than the three inner or petaloid ones. Leaves ligulate or sword-shaped, sometimes with marginal spines. The species thrive best in a well-drained compost of rich fibrous loam and leaf mould. They like plenty of light, which may be afforded by standing them on inverted pots, so as to raise their heads well up above the surrounding plants. Propagation: When the flower-spikes, which are sent up from the heart or crown of the plant, die away, suckers or offsets are produced near the base, and from these other flowers appear the year after. If large plants are desired, these suckers should be left to grow and spread around; but to produce single plants, the suckers must be taken off and potted singly, in sharp soil, and then stood where they can get a moist heat till rooted. To enable them to do this it is necessary to strip off a few of the lower leaves, and trim the bottom with a sharp knife, in order that it may heal over and callus more readily than it otherwise would. When rooted, the plants may be shifted into larger-sized pots; but for single crowns 32-sized pots are large enough, as the plants, being epiphytal in their nature, do not require much soil or any great supply of water, except when growing freely or sending up their flower-spikes. In winter, they should be kept rather on the dry side, to induce partial rest; and an important point is to see that water is not allowed to lie for any length of time in the crown of the plant, as when that is the case it is likely to cause them to rot.

A stove evergreen tree, producing very large fruit, which much resembles an orange in general appearance, very delicious to the taste, and exquisitely fragrant. This genus differs principally from Citrus by its numerous disunited stamens. The pulp of the fruit is an aperient, and a valuable remedy in dysentery, the thick rind and the dried unripe fruit are astringent. It thrives best in a rich loamy soil. Propagated by ripe cuttings, which, if not deprived of any of their leaves, will root in sand under a hand glass, in heat.

Æ. Marmelos (Marmelos). fl. white, very fragrant; panicles axillary, terminal. April. fr. fifteen-celled. l. trifoliate; leaflets toothletted. h. 10ft. India, 1759.

ÆOLANTHUS (from aiollo, to vary, and anthos, a flower; referring to the variableness of the flowers). ORD. Labiatæ. A genus of few herbs, with thickish leaves. Flowers loosely panicled. They thrive in sandy loam, and increase freely from seeds sown in a similar compost.

Æ. Livingstonii (Livingstone's). fl. brown. East Africa, 1859.

Æ. suaveolens (sweet-scented). fl. lilac, secund; cymes axillary and terminal, erect, usually trifid, with floral leaves under the divisions. July. l. nearly sessile, obovate, obsoletely denticulated, thickish, pale green. h. 1ft. Brazil, 1859. A pretty stove annual, with a sweet odour.

AERANTHUS (from aer, air, and anthos, a flower; referring to the habit). ORD. Orchideæ. A genus of a couple of species of remarkable stove orchids, requiring treatment similar to Anguloa, to which they are allied.

Æ. arachnitis (spider-like). fl. green. l. linear. h. 4in. Madagascar, 1850.

Æ. grandiflora (large-flowered).* fl. yellowish-green, large, solitary, terminal. h. 8in. Madagascar, 1823.

AERATION. The exposure of the soil to the free action of the air, as essential to the growth of plants.

AERIDES (from aer, the air; in reference to the power the species have of deriving their sustenance from the atmosphere). ORD. Orchideæ. An extensive genus of epiphytal orchids, confined to the tropics of the Old World, including many large and showy-flowered species. The majority of them are extremely handsome. The thick fleshy leaves are noteworthy for their characteristically distichous arrangement—that is to say, they are arranged in two opposite rows. They are usually truncate at the apex, and for the most part deeply channelled down the centre, but in some species terete or nearly cylindrical. All of them throw out large fleshy roots from various parts of their stems, by which they absorb the moisture from the atmosphere; and, in order to grow them successfully, they must be fixed upon blocks of wood. But this method should be adopted only whilst the plants are young, as it is almost an impossibility for the cultivator to maintain a sufficient amount of atmospheric moisture to meet their requirements; and, unless this is managed, the leaves will shrivel and fall off, leaving only a few at the extremity. Therefore, as soon as the plants are established upon the blocks of wood, let them be removed and potted. Fill the pot three parts full of broken potsherds and lumps of charcoal, and then use nothing, but clean, living sphagnum, placing a few roots in the moss and leaving the others free. By this means a greater amount of moisture can be supplied to them, and thus beautiful and symmetrical specimens obtained. The Aerides are easily grown into handsome plants, which usually bloom profusely, and thus recommend themselves to all who cultivate orchids. From early spring until the end of September they should be treated liberally with water, at the same time taking care never to wet the flowers. After the above-named time, a gradual diminution in the water supply to the roots should take place; and the atmosphere, too, should be less densely charged with moisture. But drought should never be carried far enough to cause the leaves to shrivel, for, if this is done, the uniformity of the specimen is marred; and, although we are quite willing to admit the possibility of the plants producing a greater quantity of flower spikes after a thorough shrivelling, we prefer to advocate the system that gives a fair amount of flower coupled with good leafage. As before remarked, the Aerides are peculiarly eastern, and therefore are usually classed amongst the orchids which require the hottest houses. This is, in one sense, correct; yet they do not require the great amount of heat which many imagine, and which has, until recently, been given them. They must not, therefore, be excluded from the amateur's collection of orchids. During the winter season many of the species may be kept in a temperature of 58deg. to 60deg.; whilst during the growing season the temperature may run up by sun heat without limit, so long as a free circulation of air and a sufficiency of moisture are secured. The following status of temperature may be observed: In spring, from 65deg. in the night, to 70deg. or 80deg. by day; in summer, from 70deg. in the night, to 80deg. or 85deg. through the day; in winter, about 60deg. night, and 65deg. day.

A. affine (related).* fl. delicate rose, produced, in great profusion, on branching spikes, which are sometimes 2ft. in length, and continue in bloom two or three weeks; the sepals and petals equal, rounded at the apex; the lip is sharply rhomboid and three-lobed, with a short spur. l. light green, about 1ft. long. h. 3ft. A very handsome species from India, forming an excellent exhibition plant.

A. crassifolium (thick-leaved).* This is a dwarf, densely-habited plant, with broad, thick, purple-dotted obliquely-bilobed leaves. The flowers, which are borne on long and drooping spikes, are bare—larger than those of A. falcatum, which they resemble in form, and have the segments tipped with rich purple or amethyst, the centre or throat of the flower being ivory-white. Compared with A. falcatum, the spur is here bent under at an angle, while in that plant it is straight; the side laciniæ of the lip are much broader and shorter in the present plant, and the two keels on the lip here stand close together at the base, and become divergent, whilst in falcatum they are distant at the base, and become convergent near the middle of the lip. This species is described as being the best in the genus. It may be grown near the glass, suspended in a basket. Burmah, 1877.

AEROPHYTES. Plants that are grown entirely in the air.

ÆSCHYNANTHUS (from aischuno, to be ashamed, and anthos, a flower). ORD. Gesneraceæ. A genus of very beautiful twining, radicant or parasitical stove shrubs, with opposite, simple, entire leaves, and axillary, terminal, few flowered, umbellate peduncles. They possess all the qualifications worthy of extensive cultivation—handsome flowers, fine deep green leaves, an agreeable fragrance, and are easily grown on blocks, which must be covered with green moss, fastened on with small copper wire. Preparatory to fastening them on, the roots should be covered with moss, and the plants secured to the block also by wire. After this, but little attention is requisite, except duly syringing and occasionally dipping in tepid water. As pot plants they are very beautiful, and in this method perfection is only obtained by growing them on fast and strong by generous treatment, which consists in frequently repotting in light rich compost till they are large enough to be trained up a trellis, formed of slender rods of willow or hazel. Propagated by seeds and cuttings. The former are very unsatisfactory; the latter root readily during spring in a well-drained pot, filled with a light compost, and having a surface of pure white sand, about 1in. deep. The best are obtained from half-ripened wood, cut into 2in. or 3in. lengths, and all leaves, with the exception of one or two at the top, removed. The cuttings should then be covered over with a bell glass, and placed in moderate bottom heat. So soon as rooted, transfer them singly to small pots, and again place under hand glasses, until they are thoroughly established, then gradually harden off. When about twelve months old, place the plants in their permanent quarters. Baskets are commonly and very effectively employed. Line these with moss, and fill with a light rich compost; place the plant as near the centre as possible, and, to promote a uniform growth, fasten down the branches with small neat pegs, at equal distances. During the summer, give copious supplies of water, to produce a liberal growth, which is of the utmost importance the first season, when they should not be permitted to flower. The following winter they should be kept cool and rather dry, thus giving them a rest. The year following, if properly managed, they will bloom profusely.
