Perillula reptans was karyomorphologically studied. This species had the resting chromosomes of the complex chromocenter type, the mitotic prophase chromosomes of the proximal type, and had 2n=14 chromosomes in the mitotic metaphase with basic chromosome number of x=7. The chromosome numbers of this species was reported here for the first time. The chromosome complement showed a gradual (monomodal) gradation in length from the longest (2.8 μm) to the shortest (1.7 μm) chromosomes, and consisted of six submedian-centromeric and eight subterminal-centromeric chromosomes.
