Degrees of Ploidy in Races and Species of the Phacelia magellanica-Complex


White lines between species and races indicate a complete fertility between them, races and species connected by yellow lines are only restrictedly fertile together. Races and Species with pink background are hexaploid, such with a blue background are tetraploid, and those with a green background are diploid (L.R. HECKARD, 1960).
