Cytological and morphological evaluations were carried out on some species of the tribe mimoseae and mimozygantheae from northern Nigeria so as to determine their chromosome numbers, phenology and their relationships with the soils on which they were found growing. Results from chromosome counts has confirmed the previous reports of n=14 for Entada africana and E. abyssinica,  n =52 for Leuceana leucocephala, n=13 for Mimosa pigra and n=22 for Mimosa pudica. The counts of n=52 and n=12 have also confirmed previous report for Neptunia oleraceae and Schrankia leptocarpa respectively while the count of n=14 is a new report for Prosopsis africana.  While E.africana, E.abyssinica and Leuceana leucocephala are tetraploids, Mimosa pigra and M.pudica are diploids. Chromosome number in this tribe has remained stable for long period of time. The distribution maps of the investigated taxa and their phonological data are presented for the first time.
