I have come across 4 varieties of Vinca rosea (Apocynaceae). 1. Pink flower with dark pink center 2. Pink flower with white center 3. white flower with pink center 4. pure white flower. What could be the possible explaination. Can some one help? Is it genetic variation Transposons etc. or hybrid breeding? all four were at one place. Rajendra Shinde
