Abstract

Karyomorphological details of three species of the genus Alocasia native to Thailand are presented. The somatic number and karyotypic details of the three species are: Alocasia cucullata, 2n (28) = 22m + 6sm; A. longiloba, 2n (58) = 38m + 18sm + 2a; and A. macrorrhizos, 2n (28) = 20m + 8sm. The karyotype of A. longiloba and A. macrorrhizos are first record of these species. Satellite was observed only in karyotype of A. cucullatais reported.
