Abstract: Karyotype analysis for the species Reineckia carnea (Andr.) Kunth of the monotypic genus Reineckia Kunth is given for the first time. The number of chromosomes in root-tip cell was found to be 38, which is in accord with those reported by most of the previous authors[5,7,8,9,11,12,]. The somatic complement shows a slight variation in size, i.e., the 2, 3, 5, 6, 7th pairs of the chromosomes have submedian constrictions, while the other pairs have median centromeres. The karyotype is therefore a rather symmetrical one, and according to the chromosomal terminology defined by Levan et al[4], the karyotype formula of the species is 2n=38=28 m+10 sm. In spite of the presence of two nucleoli in the telophase as observed by the authors and Noguchi[8] as well, the two corresponding Sat-chromosomes have not been found. Photomicrograph of the chromosome complement and idiogram are given in Fig. 1 and 2 respectively.
