Abstract: The genus Macrocarpium has been accepted only by a few scholars since its separation from Cornus L. by T. Nakai in 1909. Bentham, Hooker, Hutchinson and the others consider that the ovary of Macrocarpium is 2-celled and the genus should be placed back into Cornus. We have discovered that are generally I-celled. In addition, Macrocarpium is different from Cornus in basic chromosome number (X), flowering physiological character, inflorescence type and involucral scale. Thus the genus Ma-crocarpium (Spach) Nakai should be reaffirmed.

Key words: Macrocarpium, emend
