Rhytachne

Rhytachne is a genus of plants in the grass family.^[2][3] They grow principally in wet savannahs in Africa and the Americas. More specifically, they tend to prefer transitional zones between marshes and drier upland savannahs. In the Americas the genus can be found from southern Mexico and Cuba south to northern Argentina, while in Africa it is present below the Sahara, including in Madagascar. Twelve species are included, of which nine are African, two are American, and one, Rhytachne subgibbosa, is found on both continents.^[4][5] The genus is closely related to Coelorachis.^[6][7]
