Cistus albidus

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.

Description

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]

Taxonomy and phylogeny

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.
