Oryza barthii, also called Barth's rice,[2] wild rice,[3] or African wild rice,[4] is a grass in the rice genus Oryza. It is an annual, erect to semierect grass. 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 (vertisol), and is found in open habitats.[5] It is the progenitor of cultivated Oryza glaberrima, African rice.[6][7]

It has nodal roots hosting nitrogen fixing, photosynthetic strains of Bradyrhizobium.[8]

The sequenced genome of O. barthii was published in 2014.[9]

Distribution[]

O. barthii is primarily found in West Africa.[7]
