Sebaea
Sebaea is a genus of annual plants in the family Gentianaceae. Species occur in Africa, Madagascar, India, China, Thailand, Australia and New Zealand. The genus was paraphyletic and has been split in four genera: Exochaenium, Klackenbergia, Lagenias and Sebaea s.str.. Synapomorphies for Sebaea s.str. include the presence of extra stigma along the style (called diplostigmaty) and the shape of the testa cells of the seeds. The name honors Albertus Seba (1665–1736), a Dutch pharmacist, zoologist and collector. Species include (non exhaustiv list):
