Menyanthes and Nymphoides:

These are not gentians anymore

The two genera Menyanthes (buck bean) and Nymphoides (floating heart) was earlier placed in the Gentianaceae, but now belong to their own family, the Menyanthaceae. In fact, this family is not closely related to gentians at all, but has close relatives such as sunflowers (Asteraceae), lobelias (Lobeliaceae), and blue bells (Campanulaceae).
