Abstract
A new allopolyploid species of Celosia, namely, C. whiteii, collected in Malaya and originating from a natural cross between C. argentea L. (2n = 72) and C. cristata L. (2n = 36), has been described and the somatic chromosome number determined as 2n = 108. A somatic chromosome number of 2n = 18 has been determined for another species of Celosia, namely, C. trigyna L. The basic chromosome number for the genus has been determined as nine. Of the four species of Celosia so far studied cytologically, each represents a different level of ploidy, from diploid (2x) to dodecaploid (12x).
