Cistus horrens Demoly [1] | |
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 horrens generally resembles the more widespread Cistus symphytifolius . Differences include young branches covered with simple hairs; leaf blades grayer and shorter, densely covered with simple, glandular and stellate hairs on the upper surface and with longer simple hairs on the lower surface, with glandular hairs only on the nerves; sepals densely covered with simple hairs; and smaller fruiting capsules with fewer seeds. [2] The leaves are elliptical to lanceolate, stalked (petiolate) and have netted (reticulate) veins. The stigmas are longer than the stamens. [3]
Cistus horrens was first described as a new species by Jean-Pierre Demoly in 2004; [1] it had previously been treated as C. symphytifolius. [2] The specific epithet horrens is Latin for "standing erect, bristling". [4]
A 2011 molecular phylogenetic study placed C. horrens as a member of the purple and pink flowered clade (PPC) of Cistus species, along with some other Canary Island endemics ( Cistus asper , Cistus chinamadensis , Cistus ocreatus , and Cistus symphytifolius ). [5]

Cistus horrens is endemic to Gran Canaria in the Canary Islands, [3] being found in the south-west sector of the island. [2] It is typically found at elevations of 300–1,500 metres (1,000–4,900 ft) in pine forests, in semiarid conditions. [3]

Cistus albidus, the grey-leaved cistus, 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 asper is a shrubby species of flowering plant in the family Cistaceae with purple-pink flowers. It was first described in 2005 and is endemic to El Hierro in the Canary Islands.
Cistus chinamadensis is a shrubby species of flowering plant in the family Cistaceae, with purple-pink flowers, first described in 1991. It is endemic to the Canary Islands, where three subspecies occur on three separate islands. The species has been assessed as endangered in the IUCN Red List, being known only from small separated areas and facing a variety of threats.
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. It has been wrongly called Cistus libanotis by many authors.
Cistus crispus 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 heterophyllus is a shrubby species of flowering plant in the family Cistaceae.
Cistus inflatus is a shrubby species of flowering plant in the family Cistaceae, often known as Cistus psilosepalus, although this name is a synonym of the hybrid Cistus × laxus. It has white flowers.
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.
