Meiotic studies, chromosome pairing and chiasma frequency were performed on 12 species of <I>Chrysanthemum</I> (Asteraceae). All the species studied are based on x=9, the commonest base number of the genus. The present record of 2n=36 for <I>C. maximum</I> is a new tetraploid cytotype for the species. <I>C. koreanum</I> (2n=54) and <I>C. paludosum</I> (2n=18) are the two species studied cytologically for the first time. Chromosomal counts on Indian accessions of species viz. <I>C. coccineum</I>, <I>C. indicum</I>, <I>C. multicaule</I>, <I>C. pyrethrum</I> and <I>C. segetum</I> are made for the first time. Chiasma frequency ranges from 1.80-1.99 per bivalent in diploids, 2.47-3.01 per bivalent in tetraploids and 1.37 in hexaploid. Multivalents are noticed in both diploids and tetraploids.
