Very variable, particularly in S. and S.E. Europe, where a number of distinct

species have been recognized. In view of the overall variation and the known

frequency of hybridization between M. sativa and M. falcata, two of the most

distinct taxa, it seems best to treat them all as subspecies. Hybrids between

subspecies with bluish and yellow corollas often have green or almost black

corollas. The best-known of these is subsp. falcata x subsp. sativa & M. x varia 1)
