2 Myristica koordersii resembles M. impressa and M. kjellbergii; for differences see the keys. 1 Sinclair accepted M. koordersii in a wider sense than is done here, including specimens now transferred to M. impressa (type lost). The latter occurs almost throughout Sulawesi (except the Minahasa), but was by Sinclair (I.e.: 235, 481) considered to be a dubious species based on a possible atypical specimen of M. koordersii.
