Abstract

This study reports the first discovery of Sisyrinchium micranthum in Tunisia, marking the species' inaugural record on the African mainland and along the southern Mediterranean coast. The paper provides a concise morphological description of the species, an account of its phenology, and detailed information on its distribution, habitat, and ecological context in Tunisia. Additionally, we present original photographs of this diminutive annual species. An updated key to the diversity of the Iridaceae family in North Africa is also included.
