(old Greek name). Inch, Habrothamnus. Solandceaz. Greenhouse shrubs (or low trees) some of them with a climbing habit, and grown in the open in southern California and elsewhere South.

Leaves alternate and entire, usually rather narrow: flowers tubular, in axillary or terminal cymes, red, yellow, greenish or white, often very fragrant; corolla salver-shaped or somewhat trumpet-shaped, the long tube often enlarged at the throat, 5-lobed, exceeding the bell-shaped or tubular 5-toothed calyx; stamens mostly 5, all perfect, attached in the tube: fruit a scarcely succulent mostly reddish or blackish berry, derived from a 2-celled stipitate ovary and seeds few or reduced to 1. - Probably 150 species, in tropical and Subtrop. Amer. They are much grown in warm countries, where they bloom continuously. For a monograph of the West Indian species (about 20) see O. E. Schulz, in Urban, Symbolae, Antillanae, vi, p. 249-279 (1909-1910).

Cestrums are among the most useful of bright-flowering shrubby greenhouse plants, and they may be grown either as pot-plants, or planted against the back wall or supports of a greenhouse, where, if given a light position, they will produce an abundance of flowers from January to April. The Mexican species will do well in a winter temperature of 45° to 50°, but the species from Central America require stove temperature. They are propagated by cuttings taken in February or early in March and inserted in sand in a warm temperature, keeping them somewhat close until rooted, when they should be potted in a light soil, after which they may be grown in pots, shifting on as often as required, or planted out in the open ground toward the end of May in a sunny position, where, if kept pinched back to induce a bushy growth and attention is paid to watering, they will make fine plants by the first of September. They should then be lifted and potted in a light rich soil and kept close and shaded for a few days, and then transferred to their winter quarters.

After flowering, the plants should be given a rest for a month or six weeks, gradually reducing the supply of water to induce the leaves and wood to ripen, after which they should be cut well back, the old soil shaken off, and the roots trimmed back, and then either potted again or planted out for the summer. While in the greenhouse, cestrums are very subject to the attacks of insects, especially the mealy-bug. (E. J. Canning.)

A. Flowers red.


Schlecht. (Habrothdmnus elegans, Brongn.). Fig. 888. Tall and slender, half-climbing, the branches pubescent: leaves ovate, lanceolate, long-acuminate, of medium size, pubescent beneath: flowers red-purple, swollen near the top of the tube, in loose clusters which nod at the ends of the branches, the lobes ciliate. Mex. F.S. 2:82. - One of the old-fashioned greenhouse shrubs, blooming almost continuously. There is a form with variegated leaves variety Smithii (C. Smithii, Hort. Bull.) has beautiful blush-rose flowers, profusely produced through summer and autumn. Gn. 62, p. 242, desc.


Miers. Spring bloomer, with larger flowers than those of C. elegans, and more compact, nearly globular flower-clusters, the cluster subtended by small leaves as if an involucre: leaves ovate. Mex. B.M. 4183 (and probably the C. elegans, B.M. 5659.).

Newelli, Nichols. (H. Newelli, Veitch). Flowers bright crimson, larger and more brilliant than those of C. elegans and C. fasciculatum. Gn. 34:106. - A free-growing plant, originating from seed by Mr. Newell, Down-ham Market, England. Evidently an offshoot of one of the preceding species.

aa. Flowers orange or yellow.


Lindl. Of half-climbing habit: leaves oval to ovate, more or less undulate: flowers sessile in a panicle, orange-yellow. Guatemala. R.H. 1858, p. 238.

Pseudo-Quina, Mart. Glabrous: leaves membranaceous, ovate, obtusish or acute, narrowed at base: peduncles articulated at apex, axillary or in congested 4-8-flowered terminal racemes; corolla slender with acute lobes, much longer than the toothed calyx. Brazil. - Said to have marked medicinal qualities. Differs from C. Parqui in having glabrous filaments and pedicillate flowers

AAA. Flowers white, greenish, or cream-yellow.

Parqui, L'Her. Shrub, half-hardy, nearly glabrous: leaves lanceolate to oblong, petioled, short, acuminate: flowers sessile, long, tubular, with a wide-spreading limb, in an open panicle, greenish yellow, very fragrant at night. Chile. B.M. 1770. Adventive in Fla.


Linn. Quick-growing evergreen shrub, minutely pubescent or glabrous: leaves oblong and short-acute, thickish and glabrous, shining above: flowers white, very sweet-scented by day, in axillary long-peduncled spikes; corolla-lobes roundish and reflexed: berry nearly globular; filaments erect and not denticulate. W. Indies.


Linn. Night-blooming Jessamine. Shrub, 4-12 ft.: branches brownish, very slender or flexuose, glabrous or nearly so: leaves thinner, ovate or elliptic, prominently acuminate: flowers creamy-yellow, very fragrant by night; corolla-lobes ovate and blunt: berry ovoid-oblong; filamants denticulate. W. Indies.


Griseb. stems and leaves woolly-pubescent: flowers greenish, much like those of C. nocturnum and also fragrant at night. Argentina.


L'Her. Glabrous shrub: leaves ovate to oblong, glossy, thick: flowers greenish yellow and changing color (sometimes described under cult as pure white), in erect heads, slightly fragrant; corolla-tube club-shaped, tapering gradually; corolla-lobes ovate-roundish and blunt; filaments toothed: berry ovoid.
