EPISCOTHAMNUS AND BISHOPALEA, TWO NEW GENERA OF VERNON I EAE (ASTERACEAE) FROM BRASIL, AND THE RESURRECTION OF SIPOLISIA . Harold Robinson Department of Botany Smithsonian Institution, Washington, D.C., 20560. Recent material from Brasil collected by R. M. King and L, E. Bishop includes specimens of two additional undescribed genera of the Vemonieae. The new genera, Evisoothanmus and Bishopalea, are both named in honor of the second collector, Luther Earl Bishop. The study also has resulted in the redelimi-tation of Proteovsis , the resurrection of Sipotisia, and new synonymy in Aloantara and Heteroooma . The genera are considered in the above order.
