Cistus grancanariae
Cistus grancanariae is a shrubby species of flowering plant in the family Cistaceae. It was described for the first time in 2008. It is endemic to a small area in the north of the island of Gran Canaria. Description. "Cistus grancanariae" is a shrub, usually high, densely branched, with grey-green leaves clustered towards the end of the branches. The oppositely arranged leaves are around long by wide, with three (or occasionally up to five) very obvious main veins. The upper sides of the leaves are covered with short stellate (star-shaped) hairs and long simple hairs, some  glandular. The undersides of the leaves are whitish and more densely covered with hairs. The flowers are arranged in cymes, with 3–25 flowers to each inflorescence. Individual flowers are across. The petals are white, more-or-less rounded, about long and wide, with a wavy truncated apex and a short narrowed pale yellow tinged base. There are 35-70 stamens, longer than the pistil, with filaments long. The style is very short, usually less than long. Fertilized flowers produce 7–20 blackish-brown seeds up to long. Taxonomy. "Cistus grancanariae" was first described in 2008 by Águedo Marrero, Rafael Almeida and  Carlos Ríos. One of the group of white-flowered species of "Cistus", it was previously mistaken for "Cistus monspeliensis", common in Gran Canaria. The leaves of the two species are different: "C. monspeliensis" has narrower leaves, more rolled under at the edges (more revolute), with upper surfaces that are green, sticky (viscous), and without stellate hairs. Distribution and habitat. "Cistus grancanariae" is only found in a small region in the north of the island of Gran Canaria in the Canary Islands, at elevations of , where it can form quite extensive stands. There are two main populations (Cabo Verde–Los Toscales  and the Montaña de Guía) and three that are more fragmented. Plants are found in areas affected by human activity, such as deforestation, cultivation and grazing. The region is influenced by moist Atlantic winds, and has a Mediterranean-type climate, generally somewhat arid or with only seasonal rainfall, totalling a year. Conservation. "Cistus grancanariae" grows only in a limited area. Two of its locations are within protected areas, but these contain few individuals. Most of its range is unprotected and subject to human disturbance. In view of these factors, Marrero et al. consider that the species is eligible for vulnerable  (VU) status under the IUCN Red List criteria.
