A. racemosum (racemose).* fl. delicate buff coloured, in axillary racemes, large. September. Brazil, 1879. This beautiful and vigorous climber is, as yet, very rare in cultivation.
ANETHUM (from ano, upwards, and theo, to run; in reference to its quick growth). ORD. Umbelliferæ. A genus of erect glabrous annuals. Flowers yellow; involucre and involucels wanting. Leaves decompound, with linear-setaceous lobes. This genus is of no ornamental value, its most important species being the garden Dill (A. graveolens), which see for culture.
ANGELICA (in reference to the supposed angelic medicinal virtues of some species). ORD. Umbelliferæ. Perennial or biennial herbs. Flowers white; umbels terminal; involucra wanting or of few leaves; involucels of many leaves. Leaves bipinnate. The common Angelica (A. Archangelica) is the only species that calls for mention. It is a native biennial, and was at one time in much request for confectionery, and as a herb of supposed great medicinal value. Seed should be sown in September or March in ordinary soil, and the young plants thinned out to about 18in. apart.
ANGELICA TREE. See [Aralia spinosa].
ANGELONIA (from angelon, the local name of A. salicariæfolia in South America). SYN. Schelveria. ORD. Scrophulariaceæ. Very pretty stove herbaceous perennials. Flowers axillary, racemose; corolla irregular, bilabiate; lower lip saccate at the base, trifid; upper one smaller, bifid. Leaves opposite. Stem and branches quadrangular. A mixture of light turfy loam, peat, leaf soil, and sand, is a good compost. Cuttings of young shoots in spring strike readily under a hand glass, or plunged in the propagating bed, giving plenty of air daily.
A. salicariæfolia (Willow-leaved).* fl. blue, hairy, axillary, solitary, pedicellate, disposed in terminal racemes. August. l. sessile, lanceolate, acute, serrated towards the apex, finely pubescent on both surfaces. h. 1½ft. to 3ft. South America, 1818.
ANGIOPTERIS (from aggeion, a vessel, and pteris, a wing). Including Psilodochea. ORD. Filices. A genus of gigantic greenhouse ferns. Capsules eight to fifteen, opening by a slit down the side, sessile, very close but not concrete, arranged in linear-oblong or boat-shaped sori near the edge of the frond. These ferns require a very liberal supply of water, and plenty of room to fully expand. The most suitable compost is a mixture of strong loam and peat, with some sharp sand. Thorough drainage must be afforded.
A. evecta (evectic). cau. erect, 2ft. to 6ft. high, 1½ft. to 2ft. thick, very fleshy. sti. swollen and articulated at the base, furnished with two large leathery persistent auricles. fronds 6ft. to 15ft. long, bi- or tripinnate; pinnæ 1ft. to 3ft. long, spreading, the lowest the largest; rachis swollen at the base; pinnules 4in. to 12in. long, ½in. to 1½in. broad, linear-oblong, sessile or shortly stalked, acuminate; edge entire or finely toothed. Tropics of Old World. This is the only clearly defined species; the others usually known as distinct species are but varieties of it, and its culture should not be attempted if plenty of room cannot be afforded it.
ANGOPHORA (from aggos, a vessel, and phero, to bear; in reference to the shape of the fruit). ORD. Myrtaceæ. Australian evergreen greenhouse ornamental trees or shrubs. Flowers corymbose; calyx five or six-cleft. Leaves large, opposite. A mixture of leaf soil, peat, and sand suits them well. Ripened cuttings will root in sandy soil under a hand glass in a cool house, in a few weeks.
A. cordifolia (heart-leaved).* fl. yellowish, corymbose, large. May. l. sessile, ovate, cordate at the base, glabrous. h. 7ft. to 10ft. New Holland, 1789.
A. lanceolata (lanceolate-leaved).* fl. white, corymbose. May. l. petiolate, lanceolate, acuminate, glabrous. h. 4ft. to 6ft. New Holland, 1816.
