The chromosome numbers and karyotypes of six species belonging to five genera of the family Araceae distributed in natural areas from Thailand were analyzed. These species are Aglaonema modestum Schott ex Engl., Ag. simplex (Blume) Blume, Amorphophallus serrulatus Hett.& A. Galloway, Arisaema maxwellii Hett.& Gusman, Hapaline benthamiana Schott and Homalonema griffithii (Schott) Hook.f. Three of them (Aglaonema simplex, Amorphophallus serrulatus and Arisaema maxwellii) are rare or endemic species in Thailand. The chromosome number and karyotypes of all species were determined as Aglaonema modestum 2n = 40 with karyotype to be 20m + 14sm + 6st, Ag. simplex 2n = 42 with karyotype to be 6m + 26sm + 10st, Amorphophallus serrulatus 2n = 26 with karyotype to be 12m + 6sm + 8st and two satellite chromosomes, Arisaema maxwellii 2n = 24 with karyotype to be 22m + 2sm and two satellite chromosomes, Hapaline benthamiana 2n = 26 with karyotype to be 26m and one satellite chromosome and Homalonema griffithii 2n = 40 with karyotype to be 30m + 10sm and two satellite chromosomes. Karyotype analysis indicated that six species of family Araceae generally have metacentric, submetacentric and subtelocentric chromosomes. In addition, satellites were observed in Amorphophallus serrulatus, Arisaema maxwellii, Hapaline benthamiana and Homalonema griffithii. The chromosome numbers from three species of them and karyotypes from five species of them in this study were determined for the first time in this study. These cytogenetic studies of this report can be used for classification of six species in the family Araceae.
