ABSTRACT
A taxonomic revision of the genus ButeainThailandis presented. Two species, B. monosperma and B superba are enumerated. Key to species, descriptions, distributions and vernacular names are given. The habit, bark, the length of anthers, an outline and ridge of petiole, shape of epidermal axial surface and crystal types are characteristics that could be complementary for species cells on identification. The pollen morphology is, however, not taxonomically useful for identification at specific level.
