A Turkish endemic, Erodium hendrikii Alpmar, was firstly described from NE Anatolia in 1994 based on insufficient specimens. In the present study, the description of this poorly known taxon was emended by adding several macro- and micromorphological traits of its leaf and fruit observed under LM and SEM. Furthermore, it was compared with the closely related species E. malacoides (L.) L'Her. based on both morphological and molecular data and a modified identification key for the Flora of Turkey was prepared. The conservation status was also re-assessed according to the IUCN threat criteria.
