Cistus albidus, the grey-leaved cistus, [2] is a shrubby species of flowering plant in the family Cistaceae, with pink to purple flowers, native to south-western Europe and western north Africa.
Cistus albidus grows up to 1 m (3 ft) tall. Its leaves are oblong to elliptical in shape, usually 2–5 cm (0.8–2.0 in) long by 0.5–2 cm (0.2–0.8 in) wide. They have three prominent veins and are densely covered with short hairs, producing a greyish-white appearance. The flowers are arranged in cymes of one to seven individual flowers, each 4–6 cm (1.6–2.4 in) across with five purple to pink petals and five sepals. [3]
Cistus albidus was first described by Carl Linnaeus in 1753 in Species Plantarum (p. 524). [1] The specific epithet albidus means "whitish", referring to the leaves and shoots. [4]
A 2011 molecular phylogenetic study placed C. albidus as the sister to Cistus creticus in the purple and pink flowered clade (PPC) of Cistus species. C. creticus is found largely in the eastern Mediterranean, and the distributions of the two species show little overlap. They are able to hybridize, producing the fertile hybrid C. × canescens. [5]
The sister group to both species is C. heterophyllus .

Cistus horrens is a shrubby species of flowering plant in the family Cistaceae, with purple to pink flowers. It is endemic to Gran Canaria in the Canary Islands. First described as a species in 2004, it was previously identified as Cistus symphytifolius, which it resembles.
Cistus libanotis is a shrubby species of flowering plant in the family Cistaceae, with white flowers. It has been confused with Cistus clusii, which it resembles, resulting in some uncertainty in its distribution. It is endemic to the Iberian Peninsula.
Cistus munbyi is a shrubby species of flowering plant in the family Cistaceae, with white flowers. Related to and resembling Cistus clusii, it is native to Morocco and Algeria in western north Africa.
Cistus ocreatus is a shrubby species of flowering plant in the family Cistaceae, with purple-pink flowers. It is sometimes treated as synonymous with Cistus symphytifolius or as its subspecies C. symphytifolius subsp. leucophyllus. Its name is sometimes spelt Cistus ochreatus. It is endemic to Gran Canaria in the Canary Islands.
