Sebaea

Sebaea is a genus of annual plants in the family Gentianaceae.[1] Species occur in Africa, Madagascar, India, China, Thailand, Australia and New Zealand.[1][2] The genus was paraphyletic and has been split in four genera: Exochaenium, Klackenbergia, Lagenias and Sebaea s.str..[1][3][4] Synapomorphies for Sebaea s.str. include the presence of extra stigma along the style[5] (called diplostigmaty[6][7]) and the shape of the testa cells of the seeds.[1]
