Cistus osbeckiifolius is a shrubby species of flowering plant in the family Cistaceae, with pink to purple flowers.
Cistus osbeckiifolius is a shrub usually up to 1.2 m (4 ft) tall, although it may reach 1.55 m (5 ft). Its three-nerved leaves are narrow, lanceolate to elliptical in shape, and slightly pointed at the apex. [2] They are densely covered with simple hairs. [3] The flowers are about 5 cm (2.0 in) across, with pink to purple petals. [2] The stigma is longer than the stamens. [3] The fruiting capsules are brown and covered with hairs. [2]
Cistus osbeckiifolius was formally named in 1887 [1] (the epithet was originally spelt osbeckiaefolius). [4] Philip Webb collected in the Canary Islands in 1828–1830. Although he gave this species a name and wrote a description, it was not published in his lifetime (he died in 1854). [5] In 1887, Heinrich Christ published Webb's description, along with those of other plants in Webb's herbarium. [4] The epithet osbeckiifolius means "with leaves like Osbeckia".
A subspecies, C. osbeckiifolius subsp. tomentosus Bañares & Demoly, has been recognized (hence creating the nominate subspecies, C. osbeckiifolius subsp. osbeckiifolius), although as of March 2015 [update] The Plant List does not accept this taxon. [1]
A 2011 molecular phylogenetic study placed C. osbeckiifolius as a member of the purple and pink flowered clade (PPC) of Cistus species, along with other Canary Island endemics. [6]

Cistus osbeckiifolius is endemic to Tenerife in the Canary Islands. It is found at elevations of 1,400–2,400 m (4,600–7,900 ft) around Mount Teide, particularly in the region known as Las Cañadas. The climate is relatively dry and temperate to cold. [3] [2]
Cistus osbeckiifolius (as the subspecies osbeckiifolius) has been rated as " endangered" (EN) in the Spanish " Red List" (Libro Rojo de la Flora Vascular Amenazada de España). The species is considered at risk for several reasons: a limited area of distribution, restricted genetic diversity in all but one subpopulation, grazing by rabbits, the effects of fire, and human disturbance. In 2007 a fire destroyed one complete subpopulation. [2]
