A large genus of American herbs and shrubs, only one of which concerns us. The distinctly bilabiate corolla, included stamens, and 2-celled capsule are the principal characters. The genus was dedicated to Lippi, an Italian botanist.
1. L. citriodora, syn. Aloysia citriodora, and Verbena triphylla. Lemon-scented Verbena. - This favourite deciduous shrub is generally grown as a pot plant, but it will thrive and form large bushes in the South-west of England. It has slender branches and pale-green agreeably-scented lanceolate leaves arranged in whorls of threes. The flowers are very small, whitish or lilac, in terminal panicles. Chili.
Lippia nodiflora, syn. Zapania lanceolata, etc., Fog-fruit, is a tufted creeping plant from North America with spathulate or cuneate serrate leaves and axillary pedunculate bracteolate capitules of pale blue flowers.
The showy genus Clerodendron, having simple leaves and terminal panicles of brightly coloured pentamerous flowers with exserted stamens and style, and 4-celled ovaries and fruits, furnishes one or two nearly or quite hardy species for the warmer parts of the south-western coast. But they are almost unknown out of the stove or greenhouse.
C. faetidum, syn. C. Bungei, a native of Northern China, will bear our ordinary winters with impunity. It is a hand-some shrub armed with short scattered spines. Leaves ample, pubescent, cordate-acuminate, toothed, on slender petioles. Flowers lilac-rose, in dense terminal corymbs.
Callicarpa Americana, French Mulberry, is a North American dwarf tender shrub with ovate-oblong toothed leaves silvery beneath with a scurfy tomentum, and small flowers in axillary cymes, succeeded by violet-coloured berries, which constitute its chief attraction.
