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"
Elasmopalpus brown anterior and distal margins. The larvae feed on a wide range of plants but prefer grasses. Recorded host plants include a number of economically important plants such as "Phaseolus vulgaris", "Beta vulgaris", "Brassica oleracea" var. "capitata", "Cucumis melo", "Cyperus esculentus", "Zea mays", "Vigna unguiculata", "Phaseolus lunatus", "Avena sativa", "Pisum sativum", "Arachis hypogaea", "Capsicum annuum", "Oryza sativa", "Secale cereale", "Sorghum bicolor", "Glycine max", "Sorghum sudanense", "Saccharum officinarum", "Ipomoea batatas", "Lycopersicon esculentum", "Brassica rapa" and "Triticum aestivum". They tunnel into the crown of their host plant, severely weakening large plants and often killing young seedlings. They spin silken tubes near the
