Acacia Pentadenia

Acacia Pentadenia is another fine Acacia, well adapted for pot culture. Branches erect; and altho' making a nice compact bush, it does not become too dense, but is of a nice slender and open character. Leaves bipinnate, composed of two pairs of leaflets, the lower composed of seven pairs of pinnules, and in length about half as long as the upper ones, which are composed of twelve pain of pinnules. Flower heads globular, produced in twos, threes, fours, or fives, from the axis of the leaves. Peduncle one-half of an inch in length. Acacia nice plant for a greenhouse stage.

Acacia Piaemorsa

This has a rather straggling habit but it is well adapted either for pots or borders, and certainly makes handsome plants when about three feet high, though it will require skillful management in training to prevent its becoming unsightly from the loss of its lower phyl-ledea. The latter are triangular. one-third inch long. The branches grow about one foot or fifteen inches in the course of a year, and ere covered with flowers from the apex to the commencement of the season's growth. Peduncle ¼ inch long; but its phyllodes ere almost hid by its profusion of flowers, Altogether a pretty plant.

Acacia Paradoaca

Acacia Paradoaca, although of straggling growth, is suitable for pot culture, standing the knife well; phyllodes one-half inch in length, very wavy, unequal sided; situated very closely together along the stem, furnished with two sharp spines at the base of each, rendering the plant very prickly by their stiffening as they grow old. Flowers globular, of a bright yellow, produced very plentifully. Peduncles the same length as the phyllodes.

Acacia Riceana

This forms a magnificent plant for a large conservatory, towering to the height of some twenty-five feet, and producing long pendulous branches hung their whole length, as it were, with numberless bunches of flowers. The letter ere sessile, arranged upon a peduncle of from 2 ½ to 3 inches long. The phyllodes are 8-5ths inch long - linear, stiff, and nearly as sharp as needles when they get old. This plant is capable of being trained into whatever shape you may require it It also bears the knife extremely well, and is a most abundant flowerer.

Acacia Rotundiflors

Acacia Rotundiflors forms a loose spreading shrub, of about three feet high, end as much in diameter; it is most suitable for pots, Phyllodes one-half inch in length, somewhat rotundate, rather pubescent, and deep green; flowers globular, bright orange yellow, solitary, sometimes in racemes of two to four heads; peduncle ¼ inch long. This is by no means a plant of fine habit when allowed to assume its wild form; but with judicious pruning, and by training tastefully upon a balloon-shaped trellis, allowing the shoots to hang gracefully from the top, its appearance is greatly improved, and when in flower it forms a worthy inmate of our greenhouses.

Acacia Verticillata

This is one of the most interesting, and, at the same time, most beautiful and conspicuous, of Acacias, and well worthy of a prominent-position either on the greenhouse stage, conservatory shelves, or in the borders, where its graceful habit must render it a favorite. Its phyllodes, as its name implies, ere arranged in a verticillate manner, although in broken whorls of about 1-5th inch apart; the phyllodes are about 8-10ths inch in length, linear, stiff, end very sharp pointed. Its flower heeds ere about an inch in length, of en oblong shape, and seated upon a peduncle of about 8-10ths inch long; in some cases they appear singly, in others four or five flower heads are so arranged as to appear verticillate. Nothing is better than to allow this species to take its own natural habit, for the use of the knife or ligatures would not improve it.
