Cytological investigation on genus Mentha has ever been imconrpletely carried .out by a few authors (Schilrhoff 1927, Ruttle 1931, Wolf 1938, etc). The present author intends to advance it comprehensivly, and this paper is an initiate report. I. Mlentha rou,sdifolia, (L.) Huds. As material M. roundifolia, subspecies rotuudifolia Briq. was used. which is identified with morphological characters ,(Briquet 1895). It has somatic chronosome nunrber oi 24 (Nagao 1941). At Diakinesis, 12 chromosonres as bivalent are observed (Fig. Ia), and simultaneoully occurrence of 1 - 5 quadrivalents are observed (Fig. I b - g) wherein the frequency follows the Polssons' distribution (x=1.530) (Table 1. Fig. 3). At I-M. 12 chromosomes as bivalent are regularly dispersed (Fig. 4-A) and l-6 secondary association's figures of two bivaients are also observed (Fig. 4 B-M) , showing frequency of binomial distribution: (0.468+0.532)G (Tabie 2. Fig. 5).
