Abstract

Among the morphological variation in wild annual populations of sect.Beta only tepal characters show a geographic pattern, and hence can be used to distinguish different taxa. Two morphological types correspond with taxa already described:B. macrocarpa (incl.B. bourgaei) has a Macaronesian and W. to E. Mediterranean andB. adanensis an E. Mediterranean distribution area. A third type in the Aegean region is not well known yet and possibly has to be included inB. macrocarpa. Both diploid and tetraploid (x = 9) cytotypes are found withinB. macrocarpa, the latter exclusively on the Canary Islands.
