Popis:	Six taxa belonging to four species of the genus Polygonatum and one species of the genus Disporum have been studied cytologically. New chromosome number 2n=30 has been recorded in P. geminiflorum. In addition to the earlier reports made by Mehra and Pathania (1960), one more cytotype in P. sibiricum and three more cytotypes in P. verticillatum have been found to occur in the W. Himalayas. Disporum cantoniense with 2n=14 has been recorded from Nainital hills. The possible mechanisms for alteration in chromosome number and karyotype have been suggested.
