Cistus clusii is a shrubby species of flowering plant in the family Cistaceae, with white flowers, native to south west and south central Europe and north Africa.

Cistus clusii is a much branched shrub, up to 1 m (3 ft) tall.

Its leaves are narrowly linear in shape, usually 1–2.5 cm (0.4–1.0 in) long by 1–2 mm (0.04–0.08 in) wide, with edges that are turned under (revolute), green on the upper side and densely covered with short hairs on the lower side, producing a whitish appearance.

The flower stalks (peduncles and pedicels) and the sepals are covered with long white hairs.

[2] A 2011 molecular phylogenetic study placed C. clusii in a clade with Cistus munbyi in the white and whitish pink clade of Cistus species, sister to all the remaining white and whitish pink flowered species.
