The Tunisian-Algerian endemic Delphinium sylvaticum Pomel was studied in Tunisia from the morphological and biogeographical points of view. This study resulted in the enlargement of the distribution and in the description of two new subspecies: D. sylvaticum subsp. ichkeulianum El Mokni, Domina, Sebei & El Aouni and D. sylvaticum subsp. purpureum El Mokni, Domina, Sebei & El Aouni native to Tunisia in Mogods and in the North-East regions respectively. Besides ecological features and clearly separated distribution, the two new subspecies show very well differentiated morphology. An updated distribution map and an analytical key of the taxa studied are provided.
