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 t...

In Mediterranean fire-prone ecosystems, annual species specific to post-fire habitats should have a soil seed bank and should be able to germinate after a fire. Therefore, various fire-related cues can be expected to stimulate germination in post-fire annuals. Germination patterns of the rare annual Chaenorhinum rubrifolium (Plantaginaceae) were ex...

Arabis watsonii (P.H.Davis) F.K.Mey. was initially reported as Thlaspi watsonii P.H.Davis in Flora of Turkey. Although F.K.Meyer transferred this species to Arabis L., this species has been overlooked and treated as Thlaspi L. in relevant literature for Flora of Turkey. In this study this species was evaluated using molecular (nuclear ITS and plast...

Ricotia (Brassicaceae) is a genus of nine species endemic to the eastern Mediterranean region. Its phylogenetic relationships, monophyly, and tribal placement have not yet been adequately addressed.
