Keywords:Africa, lectotypification, nomenclature, William Hudson
Gypsophila elegans, an ornamental plant native to Asia and Europe, is newly reported as casual alien new to the Tunisian flora, representing also the fifth record to African continent. A population including several scattered individuals was found growing on the edge of a public garden in central eastern Tunisia in 2020 and again in 2023. Description, distribution in Tunisia, phenology and original photographs are provided, as well as a diagnostic key of the Tunisian species. Moreover, the name G. pilosa, published by W. Hudson on the basis of plants cultivated in Chelsea Garden in 1767, is here lectotypified on a specimen housed at BM.
