Botanical surveys undertaken since more than a decade in the north of the country (Biogeographic
regions of Kroumiria [K], Medjerda Valley [VM], Mogods [M] and Northeast of Tunisia [NE]), using
various North African and North Mediterranean flora which are based mainly on micro and macromorphometric
measurements through various dichotomous keys, have enumerated more than 1000
plant species. Seventeen (17) taxonomic entities, not listed in the Tunisian flora (Cuénod 1954;
Alapetite Pottier 1979, 1981; Le Floc'h & al. 2010; SIFNA 2010-2013) have been identified. These
new taxa belonging to different families (Araceae, Asteraceae, Euphorbiaceae and Orobanchaceae)
are distributed in 12 species, 1 subspecies, 3 varieties and one forma. Some of these taxa possessing
rather a North-Mediterranean distribution and linked to the flora of the other Mediterranean side will
be cited for the first time in North Africa.
Will be presented and discussed during the intervention, the different taxonomic entities recently
inventoried and the current distribution of each of them, on the Tunisian territory.
