Abstract

To have more insight into the nature of plant, plant scientists carry out phytosociological studies on such plant species. The phytosociological studies on Tridax procumbens. Linn was carried out at Imo State University, Owerri, Imo State between the months of July and September, 2018. Tridax procumbens Linn grows abundantly in the areas under tropical climate and supported by a sandy-loam soil. Morphological features showed a range of variations. Phytosociological investigation showed a Tridax- Mitracarpus-Digitaria plant community. Tridax procumbens was positively associated with Digitaria horizontalis, Mitracarpus scarber and Vernonia cinera. The Inter-relationship of T. Procumbens was thus determined. This study therefore is a contribution to the general ecology of the plant. Phytosociological studies helps plant scientist to have more knowledge into the nature of plant species. This study is a contribution to the general ecology of the plant Tridax procumbens. The study also shows that it has close association with mitracarpus Scarber and Digitaria horizontalis. More work should be carried out to find out if these plant species flower and produce seeds at the same time or not.
