Florida greeneyes, Berlandiera subacaulis

These green eyes look back at us only from Florida. There are four or five species of Berlandiera, all occurring in the southern US. They all have 30 pairs of chromosomes. This genetic similarity enables hybrids among them wherever they grow together. Ten potential species and hybrids, and that's if we ignore back crosses. These particular individuals appear to be relatively pure for this promiscuous bunch. Polk Co FL, 3/17/16.
