 Chromosome numbers and karyotypes of three species from Colutea (Leguminosae), C.delavayi, C.orientalis and C.arborescens were studied, of which C.delavayi is an endemic to SW China. C.arborescens 2n=2x=16=10m+6sm with type 2A asymmetry and C.orientalis 2n=2x=16=12m+4sm with type 1A asymmetry, the basic chromosome number 2n=16 is also confirmed. C.delavayi 2n=2x=16=16m with type 1A asymmetry was reported firstly.
