Cytological survey of Millettieae

Chromosome number in Millettieae

The chromosome number in Millettieae is n=10, 11, 12, with most of the species as n=11 (Tephrosia, Derris, Lonchocarpus, and Millettia). Aganope and Leptoderris seem to have n=10 instead. The most distinguishing genera are Callerya (n=8, 16) and Wisteria (n=8, 16), which confirms molecular data that these two genera might not belong to core-Millettieae clade.

Here are three links you can see the list of chromosome numbers in Millettieae had been surveyed:
