Abstract
The morphology and biogeography of the Tunisian–Algerian endemic Delphinium sylvaticum Pomel has been studied in Tunisia. As presented here, this study resulted in an enlargement of the known 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 northeast regions, respectively. Besides ecological features and clearly separated distribution, the two new subspecies show very well differentiated morphology. An updated distribution map and a diagnostic key of the studied taxa are provided.
