Gynerium
Gynerium is a monotypic genus of Neotropical plants in the grass family, native to Mexico and Colombia, 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, "caña brava" in Peru and Colombia, "chuchío" in eastern Bolivia, and "tañil" in 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).
Being one of the first plants to colonise open areas, G. sagittatum is an important pioneer species that reaches new sites via wind-distributed seeds. Once established, it spreads vegetatively, and is found usually near rivers and lakes, and even beaches.
In Colombia its straw is used to create different accessories including the traditional sombrero vueltiao, symbol of Colombia.
