This study assessed the morphology and distribution of Piptadeniastrum africanum (Hook.f.) Brenan and Cathormion altissimum (Hook.f.) Hutch. & Dandy in Bayelsa state, Nigeria. Field study was carried in 36 communities across the 8 Local Government Areas in Bayelsa state from 2014 - 2018. The morphological characteristics were studied based on physical observations. The study found that the two plants are characteristically different based height, number of pinnae and leaflets, length and of seeds. Other distinguishing morphological characteristics are the smooth or spiny nature of their stems and the petals arrangement. The study also found that C. altissimum is evenly present in the riverine communities when compared to P. africanum. The decline in the relative abundance of P. africanum is due to over exploitation as a result of its premium value as timber species for construction and carpentry words. The study has been able to resolve the problematic taxonomy of the plants among some indigenous people of Bayelsa state who claim that the plants are the same, existing as upland and water species or one is male and the other is female. Again, there is the need for the conservation of these plant species within the locality especially P. africanum.
