'''''Cistus'' × ''incanus''''' <small>L.</small> is a hybrid between ''Cistus albidus'' and ''Cistus crispus''.<ref name=GuzmVarg05/> The name "''Cistus incanus''" (synonym ''C.&nbsp;villosus'') has been used by other authors in a different sense, for ''Cistus creticus'' (at least in part). The English name '''hoary rock-rose''' may refer to this species, among others.<ref name=BSBI07/>

==Description==

Because of confusion between the original species named by Linnaeus in 1753 and the way in which the name was used by later authors (see § Taxonomy), plants described under this name may actually belong to different species. ''C.''&nbsp;×&nbsp;''incanus'' is a shrubby plant, to about {{convert|1|m|ft|abbr=on|0}} tall, with grey-green leaves and pink to purple flowers.

==Taxonomy== The name ''Cistus incanus'' was first used by Carl Linnaeus in 1753 in ''Species Plantarum''.<ref name=TPL_kew-2723448/><ref name=Linn53/> Confusion exists among this name and two later names published by Linnaeus, ''Cistus creticus'' in 1762 and ''Cistus villosus'' in 1764. There is general agreement that ''C.&nbsp;villosus'', at least as used by later authors, is not a distinct species. Two treatments are then found.

In the first, generally older, treatment, ''C.&nbsp;incanus'' is accepted, with ''C.&nbsp;villosus'' being a synonym.<ref name=ITIS_501569/> ''C.&nbsp;creticus'' is treated as ''C.&nbsp;incanus'' subsp. ''creticus''.<ref name=ITIS_507742/>

According to Demoly (1996), Linnaeus's ''Cistus incanus'' was recognized to be a hybrid as early as 1904.<ref name=Demo96/> The second treatment (followed here) is based on this recognition. ''C.&nbsp;creticus'' is accepted, with ''C.&nbsp;villosus'' as a synonym.<ref name=TPL_kew-2723343/> ''C.'' × ''incanus'' <small>L.</small> is treated as the hybrid ''C. albidus'' × ''C. crispus''.<ref name=GuzmVarg05/> As used by previous authors, but not Linnaeus, the name "''C.&nbsp;incanus''" is taken to refer to ''Cistus creticus'', particularly ''C.&nbsp;creticus'' subsp. ''eriocephalus''.<ref name=TPL_kew-2723345/> Two formerly recognised subspecies of ''C. incanus'' are regarded as subspecies of ''Cistus creticus'': *''Cistus'' × ''incanus'' subsp. ''corsicus'' = ''C. creticus'' subsp. ''corsicus''<ref name=TPL_kew-2723344/> *''Cistus'' × ''incanus'' subsp. ''creticus'' = ''C. creticus'' subsp. ''creticus''
