Cistus × incanus is a hybrid of Cistus albidus and Cistus crispus . The name " Cistus incanus " ( synonym : Cistus villosus ) was used in various ways by various authors, partly for Cistus creticus . The name "Graubehaarte Zistrose" (English "hoary rock-rose") can be used, among other things,to referto Cistus incanus .

description

As Cistus incanus designated plants can include various types. The reason is the confusion of the species originally named by Linnaeus with other species by later authors (see § Taxonomy). Cistus × incanus is a Chamaephyte , growing up to 1 meter high with gray-green, very hairy leaves and pink-purple flowers.

Taxonomy

The name Cistus incanus was first used by Carl von Linné in Species Plantarum in 1753 . Confusion exists between this name and two later names published by Linnaeus, Cistus creticus (1762) and Cistus villosus (1764). There is scientific consensus that C. villosus , at least as used by later authors, is not a distinct species. Two alternatives are presented for this:

According to the first, C. incanus and C. villosus are considered synonyms. C. creticus is called C. incanus subsp. named creticus .

The second solution is based on the knowledge that Cistus incanus is a hybrid (Demoly (1996)). After that, C. creticus and C. villosus are synonyms. C. × incanus L. is referred to as a hybrid between C. albidus × C. crispus .

Other earlier authors, but not Linnaeus, refer to C. creticus as C. incanus , especially C. creticus subsp. eriocephalus

Two previously recognized subspecies of C. incanus are considered subspecies of Cistus creticus :

  • Cistus × incanus subsp. corsicus = C. creticus subsp. corsicus
  • Cistus × incanus subsp. creticus = C. creticus subsp. creticus
