Abstract The Ignatius Ajuru University of Education's main campus, located at Rumuolumeni, Port Harcourt, Rivers State, is fl oristically unique. A survey of the vascular plants was carried out to determine the species composition and life form. The purpose of this study was to provide a vouchered fl oristic inventory and to document any occurrences of rare or endangered taxa. The fl oristic survey was conducted over parts of two growing seasons (from the 21 August 2011 to 5 August 2012) during which the specimens were collected on approximately weekly to biweekly intervals. A total of 132 species in 102 genera and 40 plant families were collected, including 2 ferns, 2 gymnosperms, 60 monocotyledons and 68 dicotyledons. The most diverse family was the Poaceae, with 30 species, followed by the Asteraceae, Juncaceae, Fabaceae and Euphorbiaceae represented by 10, 9, 8 and 7 species, respectively. The most diverse genus was Juncus, followed by Pennisetum, with 6 and 4 different species, respectively.
