outer sepals usually spreading, much smaller than the inner ones, which 
are usually 2- or 4-ribbed, furrowed, with scarious margins, with the inner 
surface shining, and with the angles generally pilose. Petals 2, 3, or 4 times 
longer than the calyx. Stamens numerous. Style bent at the base, but 
somewhat club-shaped at the apex. Stigma simple. Capsule covered by 
the calyx, 3-valved, l-celled, opening at the apex. Seeds few, convex on 
the outside, and angular on the inside. Subshrubs, with the stems 
branched from the base ; branches numerous, erect or procumbent, but ge- 
nerally ascendent. Leaves opposite, on short footstalks; lower ones 
smallest, usually with revolute margins, stipulate. Stipules linear-lanceolate. 
Racemes terminal, secund, simple, curved backwards before flowering ; after 
flowering erect, elongated. Pedicels laterally bracteate at the base, droop- 
ing before flowering; when in flower erect, after flowering recurved or 
reflexed. (Don’s Mill., i. p. 310.) Evergreen undershrubs, bushes, and 
trailers, of the smallest size; natives of Britain, and the southern part of the 
en continent. Many of the sorts are hybrids originated in British 
gardens.

Varieties. De Candolle notices H. 2. syriacum, the Cistus syriacus of Jacquin; and Persoon records H. 
tl. Thibaridi, the Cistus racemdsus of Cavanilles. 
Spec. Char., &c. Stem suffruticose, erect, branched. Branches long, terete, canescent. Leaves ob- 
long-linear, with revolute margins ; under surface tomentose, hoary ; younger leaves canescent on 
both surfaces. Stipules and bracteas linear, acute, ciliated. Racemes 1—3-flowered, terminal. 
Flowers crowded. Calyxes glaucous. Sepals ciliated, outer ones minute; these become reflexed 
after flowering: inner sepals 2-nerved, oblique, acute. (Don’s Mill., i. p. 310.) A bush about 1 ft. 
in height, a native of the south of France, and found also in Barbary, Spain, and Syria, in dry 
places ; producing its yellow flowers in Juneand July. It was introduced into England in 1739, and, 
probably, is now lost, or confounded with some other sort.

Spec. Char. &c. Stem erect. Branches hoary, tomentose. Leaves oblong-linear, bluntish, somewhat

gins. Stipules rather villous, linear-lanceolate. Racemes revolute before flowering. Flowers 
crowded. Calyxes villous. Outer sepals ciliated, green, inner ones acuminated, hoary. (Don’s Mill.,

yellow flowers in June and July.

Varieties, De Candolle (Prod., i. p. 279.) records three forms of this species : one with the stipules 
longer than the footstalks of the leaves; another, with the stipules setaceous, shorter than the 
footstalks of the leaves; and the third with procumbent branches, shorter leaves, and racemes 
few-flowered. 
Spec. Char., §c. Stem shrubby, branched, somewhat procumbent. Branches 
simple, erect, hoary-tomentose. Leaves rather tomentose; under surface ca- 
nescent, upper surface glaucous with revolute margins ; lower leaves almost 
round; middle ones elliptical, obtuse ; upper ones, lanceolate, acutish. Stipules 
and bracteas erect, linear, oblong, villous, rather greenish. Calyxes yellowish- 
glaucous, minutely pubescent. (Don’s Mill., i. p. 310.) A procumbent plant, 
with large dark yellow flowers, found in Spain and Barbary, and, according 
to Sweet, cultivated in the Chelsea Botanic Garden in 1826, where, growing 
on rockwork, it covered more than a yard in diameter, and made a grand 
appearance in June and July, when it was covered with flowers. It is one 
of the most ornamental species of the genus, and no collection ought to be 
without it, if it were only for planting out in borders in the summer season.
