[email protected] (Manuscript received 10 March 2010; accepted 10 May 2010) ABSTRACT: The genera and species of Vernonieae in China are reviewed using revised generic concepts. The recognized genera are Acilepis, Baccharoides, Camchaya, Cyanthillium, Decaneuropsis, Distephanus, Elephantopus, Ethulia, Gymnanthemum, Khasianthus, Monosis, Pseudelephantopus, Strobocalyx, and Tarlmounia. The pollen of each genus is described and illustrated. Keys are provided to genera and species. KEY WORDS: Vernonieae, Asteraceae, pollen, SEM, generic descriptions, keys, China. the completed results on a country by country basis, and INTRODUCTION not to wait for resolution of species in other areas such Generic revisions in the tribe Vernonieae during the as India (Uniyal, 1995) which has a more complex last 30 years have been generally completed for the Vernonian flora. Of additional interest in the case of Western Hemisphere members (Robinson, 1999b), but China, most of the genera seem to have distinctive were only partially and inadequately dealt with in the forms of pollen. For that reason, pollen is reviewed and Eastern Hemisphere members (Robinson, 1999a). These illustrated with SEM micrographs for each genus. treatments were summarized in the Kubitzki volume (Robinson, 2007).
