1. The Karyotypes of 2 species in genus Allium are reported.
2. The Karyotype formula are as follows :
Allium fitsulosum L.
K(2n) = 16 = 2<A_1>^m + 2<A_2>^sm + 4B^<sm> + 2<C_1>^m + 2<C_2>^<sm> + 2^tD^<st> + 2E^m
Allium nipponicum Franch. et Savat.
K(2n) = 32 = 4A^m + 2<B_1>^m + 2<B_2>^<sm> + 2cs<C_1>^<sm> + 2<C_2>^<sm> + 2^t<D_1>^<st> + 2<D_2>^<sm> + 2^t<E_1>^<st> + 2<E_2>^m + 4<E_3>^<sm> + 4<E_1>^<sm> + 2<F_2>^m + 2G^<sm>
