The genus Strobocalyx is resurrected from the synonymy of Gymnanthemum and Vernonia, and the genus Tarlmounia is described. Both of these Asian and Malaysian genera have distinct stylar nodes, blunt stylar hairs and specialized tricolporate, echinate pollen. Strobocalyx is typified by the Asian and Indonesian S. arborea, and combinations are provided for the 6 other East Asian and Malaysian species: Vernonia bockiana, V. chunii, V. esculenta, V. solanifolia, V. sylvatica and V. vidalii. Tarlmounia contains only Vernonia elliptica.
