'''''Cistus munbyi''''' is a [[shrub]]by [[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.

==Description== ''Cistus munbyi'' has narrow linear leaves with a single prominent vein, generally {{convert|6|–|30|mm|in|abbr=on|1}} long by {{convert|1|–|4|mm|in|abbr=on|1}} wide, with edges that are turned down (revolute). The upper surfaces of the leaves are smooth, the lower surfaces have a dense covering of short stellate hairs. It has white flowers.<ref name=GuzmLled09/> ''C.&nbsp;munbyi'' resembles ''[[Cistus clusii|C.&nbsp;clusii]]'', but the flower-bearing branches are longer and the flower stalks ([[Peduncle (botany)|peduncles]]) and [[sepal]]s are covered with white hairs, making them appear silky ("''sericeus''").<ref name=Munb47/>

==Taxonomy== [[Giles Munby]] gave a description of this species under the name ''Cistus sericeus'' in 1847.<ref name=Munb47/><ref name=TPL_kew-2723652/> The name had already been published by [[Martin Vahl]] in 1790, so that Munby's name is [[Nomen illegitimum|illegitimate]].<ref name=IPNI/> [[Auguste Nicolas Pomel]] published the currently used name in 1874,<ref name=TPL_kew-2723526/> the specific epithet ''munbyi'' honouring Munbyi.

==Phylogeny== [[Molecular phylogenetics|Molecular phylogenetic studies]] place ''C.&nbsp;munbyi'' in a [[clade]] with ''[[Cistus clusii]]'' within the larger [[Cistus#Phylogeny|white and whitish pink clade]] of ''Cistus'' species, sister to all the remaining white and whitish pink flowered species.<ref name=GuzmVarg05/><ref name=CiveLeclDemoAgna11/>

==Distribution and habitat== ''Cistus munbyi'' is native to western north Africa, occurring at elevations of up to {{convert|100|m|ft|-1}} along the Mediterranean coasts of [[Morocco]] and [[Algeria]]. It occurs in dry, sunny locations, generally in [[Alkali soil|alkaline soils]] among bushy vegetation.<ref name=GuzmLled09/> Munby's description was based on a specimen from the cliffs east of [[Oran]].<ref name=Munb47/>
