Explanations

Genome designation
AA
Chromosome number
Diploid, 2n=24
Distribution
Tropical African Savannah = Benin, Botswana, Burkino Faso, Cameroon, Central African Republic, Chad, Cote d’Ivoire, Ethiopia, the Gambia, Ghana, Guinea, Mali, Mauritania, Namibia, Niger, Nigeria, Senegal, Sierra Leone, Sudan, Tanzania, Zambia.
Key characteristics
Short ligule (O. longistaminata has long bifurcate ligule), spikelets large (7.8-11mm), shattering, long strong, usually red awns, panicle rarely has secondary branching. Annual.
Habitat
Open, wet habitats, seasonally deep water, stagnant water or slowly flowing water or pools. Can be found sympatric with O. longistaminata or O. brachyantha.
Potentially useful traits
Drought avoidance
Notes
The presumed progenitor of O. glaberrima. Perennial O. longistaminata and annual O. barthii and O. glaberrima are easily distinguished on the basis of ligule length, which is short and rounded in the African annual species and long and pointed in the African perennial species.
