Abstract


Rumex tunetanus is a strictly endemic species occurring on the banks of the dried lake of Sejenane (NW-Tunisia) which was discovered in 1888 (published in 1899), but never seen until our rediscovery in 2009. This finding allowed us to give a more complete morphological description of the species, as well as to specify its ecological preferences and conservation status. A lectotype preserved at P was designated for the name Rumex tunetanus.
