Abstract

Heldreichia Boiss. is a monospecific genus mainly distributed in Anatolia and the Lebanon. Although morphological variation and infrageneric phylogenetic relationships were recently studied in detail, Heldreichia remained as one of the few orphan genera that have not yet been assigned to any tribe. In the current study, we used sequence data from the nuclear ITS and chloroplast ndhF regions of Heldreichia and representatives of main Brassicaceae lineages and tribes to determine its tribal affiliation. Bayesian-based phylogenetic analyses clearly show with high support that Heldreichia is a member of the recently expanded tribe Biscutelleae. Furthermore, we characterize the tribe Biscutelleae morphologically and provide a determination key for all its genera.
