An Iranian floristic link with Socotra in Hypericum ( Hypericaceae).

Hypericum dogonbadanicum Assadi, a local species from the Quercus brandtii forests of the Zagros Mountains in south-western Iran, belongs to sect. Campylosporus ( Spach) R. Keller and is most closely related to a Socotran endemic, H. socotranum Good subsp. smithii N. Robson. Despite the inclusion of these forests in the Irano-Turanian Element of the Iran flora by Zohary (1963), H. dogonbadanicum appears to belong rather to the Mediterranean dwarf-shrub maquis type of community and therefore to be a member of Zohary's (1963) Mediterranean/Irano-Turanian group of Iranian species.-The key position of the Socotran endemics to the understanding of the inter-sectional relationships is discussed.
