Notes:
There are two cytogenetically well differentiated genomes, A (x=8) and B (x=9), in the Scilla scilloides complex. The principal cytogenetic types form an aneuploidal series of chromosome numbers, i.e., AA (2n=16), BB (2n=18), ABB (2n=26), BBB (2n=27), AABB (2n=34), ABBB (2n=35), BBBB (2n=36), and AABBB (2n=43). These types are widespread in the Japanese islands, excepting AA which is confined to Korea. On the contrary diploid BB is not known from Korea. However, polyploids AABB and AABBB are known from both Japan and Korea. Plants of the complex do not grow in wild lands or montane regions, but in close relation to man's activities, e.g., in agricultural lands, on river banks, along roadways and railway lines, and in graveyards. Natural populations are, as a rule, a mixture of many different cytogenetic types.
