Abstract

Both chromosome numbers and karyotype structure from 15 wild North-African populations of Delphinium L. sect. Delphinium were studied. Delphinium balansae Boiss. & Reuter, with a more symmetrical karyotype, appears as a possible perennial ancestor of' the remaining annuals with highly asymmetrical and shorter karyotype. A taxonomical reorganization of this section is proposed: two new series (ser. Macropetala ser. nova and ser. Balansae ser. nova.) and two new nomenclatural combinations (D. nanum subsp. alboliliaceum and D. nanum subsp. elongatum) are proposed.
