Abstract

Botanical surveys within Tunisian territory undertaken during the last two decades led to the discovery of many scattered and extended populations of Centaurea hyalolepis subsp. hyalolepis (Centaurea sect. Calcitrapa, Asteraceae). A taxon, native in the east Mediterranean to Iran and Arabian Peninsula but widely naturalized in many european countries, here firstly reported for Tunisia. The plant seems to be well-established and takes part within ruderal/sub-nitrophilous vegetation, representing the first case of appointment/naturalization in Tunisia. Phenology of the species as well as original photographs are here provided.
Los estudios botánicos realizados en el territorio tunecino durante las últimas dos décadas condujeron al descubrimiento de muchas poblaciones dispersas y extendidas de Centaurea hyalolepis subsp. hyalolepis (Centaurea sect. Calcitrapa, Asteraceae). Se trata de una taxón nativo del Mediterráneo oriental, hasta Irán y la Península Arábiga, pero ampliamente naturalizado en muchos países europeos, que se cita aquí por primera vez para Túnez. La especie parece estar bien establecida aquí formando parte de la vegetación ruderal/subnitrófila, por lo que se trata de la primera cita sobre su naturalización en Túnez. Se proporciona aquí la fenología de la especie así como fotografías originales.
