Chromosome counts of Compositae are reported from Mexico, Central America, Ecuador, and Chile. First counts are reported for 20 species in Baccharis, Calea, Erigeron, Eupatorium, Heliopsis, Isocarpha, Liabum, Monactis, Pinaropappus, Senecio, Sigesbeckia, Simsia, Spilanthes, Verbesina , and Viguiera . Additional counts also are provided for 65 populations of taxa counted previously, of which 10 are new numbers. The systematic implications of certain of these counts are discussed.
