ResumoNew chromosome counts are provided for 234 populations of the tribe Eupatorieae including the first reports for the genera: Asplundianthus, Carminatia, Cronquistia, Decachaeta, 2 70 of the 160 known genera.Cytology is correlated with recent taxonomic revisions including new generic concepts and "унты бун of many vouchers of previous cytological studies.The number n = 10 is regarded as basic for the tribe; it is the most common in the tribe and of the Brickellia series with x = 9 and members of the Piqueria, Stevia, Carphochaete, Micro--series with x -11 and 12.The Bartlettina series has a base of x -16 but is closely relate Hebeclinium with x -10.Other groups with higher numbers are more cine, Neominnded subgenus Critoniopsis with x -17, subgenus Neomirandea with x -25, Mikania with x -16-20, Ageratina with mostly x -17, Oxylobus with x -16.Hofmeis.teri mee x = 18-19 is regarded on other bases as one of the m distinctive elements in the tribe.Individual examples of reduction in groups with a base of x -10 are e Adenostemma involucratum with n -5 and the weedy F leischmannia microstemon with nThe present paper continues a series dealing with chromosome numbers of
