What is "gynerium"

Gynerium is a monotypic genus of Neotropical plants in the grass family, native to Mexico, Central America, South America, and the West Indies. It is classified in its own tribe Gynerieae.

The sole species in the genus is Gynerium sagittatum, a tall grass that grows up to six metres (twenty feet) high. It is a very vigorous species that grows into a considerably dense mass of vegetation. The species is known as "cana-do-rio", "cana-flecha", "cana-frecha", "ubá" and "cana-brava" in Brazil, and "caña brava" in Peru, "tañil" in Cahabon, Alta Verapaz, Guatemala and other Spanish speaking countries. It is known in English as "wildcane" or "wild cane", while "arrow cane" is less common (sagitta is Latin for arrow).
