hue.” The remedy for this is, of course, to have the pot thoroughly well-drained hy filling the bottom up to 
tiearly one quarter of its depth with broken potsherds, and taking care not to let the pot stand either in a saucer 
or on the ground. There are two or three other species, one of which (A. alhicans) has fragrant white flowers, and 
another (A. Uttorea) has yellow flowers.

Generic Character. — Limb of the corolla conduplicate in a:stivation, plicate. Stamens inclosed. Berry one-celled, few-seeded. 
Placentas central, free. 
Description, &c. — Most of the species of this genus are not ornamental, hut one which has lately been 
introduced is very much so. One peculiarity in this genus is, that though the flowers are usually sweet-scented, 
the leaves have a peculiarly disagreeable smell when bruised. The name of Cestruni is from the Greek word 
Kestron, which signifies hetony ; but there does not appear any reason why it should he applied to this plant.

Engravings. — Bot. Reg., for 1845, t. 22; Paxton’s Mag. of Bot., 
vol. xiv., p. 77 ; and our fig. 6, in PL 40. 
Specific Character. — Glabrons. Leaves petiolate, oval-acute, un- 
dulated. Flowers sessile, spicate. Bracteas deciduous. Calyx five- 
ribbed, five-toothed. Corolla glabrous, funnel-shaped, with a reflexed 
limb. Filaments pubescent at the base. Berries pear-shaped. 
Description, &c. — This species is very ornamental, having large dark-green shining leaves, bright orange 
flowers, and abundance of snow-white pear-shaped berries, which remain on during winter after the leaves have 
fallen. The flowers have the pleasant perfume of orange-peel, hut the berries are said to be poisonous. The plants 
are said to flower best when their pots ai’e set out in the open air for a few weeks in early summer. They should 
be taken into the greenhouse as soon as the flower-buds are formed. The flowers generally begin to expand in 
August, and they continue till the latter end of October or November. The species is a native of Guatemala, and 
it was introduced in 1844.
