It has leaves with a short ligule (<13 mm), and panicles that are compact to open, rarely having secondary branching. The inflorescence structure are large spikelets, 7.7-12.3 mm long and 2.3-3.5 mm wide, with strong awns (up to 20 cm long), usually red. The inflorescences have anthers 1.5–3 mm long.
This wild rice grows in sub-Saharan Africa, and is found in mopane or savanna woodland, savanna or fadama. O. barthii grows in deep water, seasonally flooded land, stagnant water, and slowly flowing water or pools; it prefers clay or black cotton soils, and is found in open habitats.[2] It is the progenitor of cultivated Oryza glaberrima, African rice.[3]
