Gynerium
''Gynerium'' is a genus of Neotropical plants in the grass family, native to Mexico, Central America, South America, and the West Indies.〔(Willdenow, Carl Ludwig von ex Palisot de Beauvois, Ambroise Marie François Joseph 1812. Essai d'une Nouvelle Agrostographie 138-139 ) description in Latin, commentary in French〕〔(Willdenow, Carl Ludwig von ex Palisot de Beauvois, Ambroise Marie François Joseph 1812. Essai d'une Nouvelle Agrostographie plate XXIV (24), figure VI (6 a-d) ) line drawings of ''Gynerium sagittatum''; (figure captions on caption page 16 )〕 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''). == Description == The stems are straight and erect, the lower part is covered with "vainas" from the fallen leaves, while in the middle part the leaves are arranged in fan shaped groups. The upper part, round and thin, stiff on the outside and soft on the inside, develops a large bloom at the top. There are many varieties in the plant's stems. The bark zone, which is the main factor in the unusual height, functions as a water distribution system, transporting water from the underground roots to the superior part of the plant including the leaves. This vital function occurs at any season of the year.
