Synonymes. Cisti species of Lin. ; Heliantheme Sonnen Gurtel, Ger. ; Eliantemo, Jtal. 
Derivation. From hélos, the sun, and anthemon, a flower ; because the flowers open with the rising 
of the sun in the morning, and the petals fall off with the setting of the sun in the evening. The 
flowers of Helianthemum, as well as of Cistus, only last for a few hours when the sun shines; and 
if the weather is dull, and the sun does not make its appearance, the flowers do not open, but 
remain unexpanded. Should this continue for several days together, they will decay in the bud. 
Gen. Char. Calyx of 3—5 sepals ;-the two outer usually smaller than the 
inner ones, rarely larger. Petals 5, usually regularly denticulated at the 
top. Stigma capitate. Style sometimes almost wanting, sometimes straight, 
sometimes oblique, and sometimes bent at the base. Ovary triquetrous. 
Capsule 3-valved. Seeds angular, smooth. 
Leaves simple, opposite or alternate, stipulate or exstipulate, sub-ever- 
green; 3-nerved or feather-nerved. Flowers axillary or terminal. Pedicels 
usually furnished with bracteas at the base. — Shrubs or subshrubs, low, 
prostrate, resembling herbaceous plants ; natives of Europe; and of the 
easiest culture in any common soil.

Spee. Char., §c. Stem suffruticose, procumbent, branched, branches elongated. 
Leaves scarcely revolute at the margins; under surface cinereously hoary ; 
upper surface green, pilose, somewhat ciliated. Lower leaves 
somewhat orbicular, middle ones ovate-elliptical, upper ones 
oblong. Stipules oblong-linear, ciliated, longer than the foot- 
stalks of the leaves. Racemes loose. Pedicels and calyxes 
pilose. (Don’s Mill.) A procumbent sub-evergreen under- 
shrub. Europe and Britain, in dry and hilly pastures. Height 
Gin. to 1 ft. Flowers yellow; May to September. 
Varieties, There is a very handsome double-flowered variety, 
with pale yellow flowers ; and another, called Lee’s new double 
yellow, with dark yellow flowers; both of which are in general 
cultivation in the nurseries. De Candolle also notices two 
forms of the species: one with tomentose pubescent branches, 5+ H- vulgare. 
and stipules scarcely longer than the footstalks of the leaves ; and another 
with branches glabrous at the base, but pubescent upwards, and the stipules 
twice or thrice the length of the petioles of the leaves, 
The stamens, if touched during sunshine, spread slowly, and lie down upon 
the petals. (Smith.) “A very variable species,” even in a wild state; and, 
in gardens, many beautiful varieties, single and double, have been originated 
from it by cross fecundation with Continental helianthemums, and perhaps with 
cistuses,
