These species are <em>Aglaonema modestum</em> Schott ex Engl., <em>Ag. simplex</em> (Blume) Blume, <em>Amorphophallus serrulatus</em> Hett. &amp; A. Galloway, <em>Arisaema maxwellii</em> Hett. &amp; Gusman, <em>Hapaline benthamiana</em> Schott and <em>Homalonema griffithii</em> (Schott) Hook.f. Three of them (<em>Ag. simplex</em>, <em>Am. serrulatus</em> and <em>Ar. maxwellii</em>) are not common and endemic species in Thailand. The chromosome number and karyotypes of all species were determined as <em>Ag. modestum</em> 2<em>n</em> = 40 with karyotype to be 20m + 14sm + 6st, <em>Ag. simplex</em> 2<em>n</em> = 42 with karyotype to be 6m + 26sm + 10st, <em>Am. serrulatus</em> 2<em>n </em>= 26 with karyotype to be 12m + 6sm + 8st and two satellite chromosomes, <em>Ar. maxwellii</em> 2<em>n </em>= 24 with karyotype to be 22m + 2sm and two satellite chromosomes, <em>Ha. benthamiana</em> 2<em>n </em>= 26 with karyotype to be 26m and one satellite chromosome and <em>Ho. griffithii</em> 2<em>n </em>= 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 <em>Am. serrulatus</em>, <em>Ar. maxwellii</em>, <em>Ha. benthamiana</em> and <em>Ho. griffithii</em>. 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.<span class="Apple-converted-space"> </span></p> ER -
