Abstract: The present paper deals with a study of the karyotypes of two species of the genus Lycoris Herb.---L. anhweiensis Y. Hsu et Fan and L.chinensis Traub. The number of cbromosomes in root-tip cell of these two species has been found to be K(2 n) = 16 (Fig. 1 and 2 ), both species exhibited bimodal karyotypes with 6 V-shaped and 10 I (rod) -shaped chromosomcs each. Accor- ding to Levan et al., the karyotype formulas of L. anhweiensis and L. chinensis are therefore K (2n) = 16= 6 m + 4t+ 6t(SAT) and K (2n) = 16 =6rn + 6t+2t (SAT) respectively. The chromosome count and karyotype of the former species is reported for the first time.
