Abstract: Ecological distribution of Tithonia diversifolia (Hemsl). A. Gray was studied in six states of the southwestern Nigeria using three locations in each of the States. The presence of T. diversifolia was recorded in all the States and locations surveyed in varying numbers with associated weeds. Survey data were analysed using detrended correspondence analysis (DCA). The first two ordination axes of the DCA accounted for 67.2% (Axis 1, 40.6%; Axis 2, 26.6%) of variance on the site and species components. The DCA separated Ogun State locations from others. T. diversifolia was found to be closely associated with Boerhavia coccinea, Fleurya ovaliflora, Indigofera subulata, Merremia dissecta, Mimosa pudica, Momordica foetida, Phyllanthus mimosoides, other species of Phyllanthus, Physalis angulata, Schrankia leptocarpa and Sesbania parchycarpa in Ekiti, Lagos, Ondo, Osun and Oyo States while these species were absent in Ogun State.
