군네라 마니카타-[정명] Gunnera manicata Linden ex Delchev.

Gunnera manicata, known as Brazilian giant-rhubarb or giant rhubarb, is a species of flowering plant in the family Gunneraceae from the coastal Serra do Mar Mountains of Santa Catarina, Parana and Rio Grande do Sul States, Brazil. In cultivation, the name G. manicata has regularly been wrongly applied to the hybrid with G. tinctoria, G. × cryptica.

Description

Gunnera manicata is a large, clump-forming herbaceous perennial growing to 2.5 m (8 ft) tall by 4 m (13 ft) or more. The leaves of G. manicata grow to an impressive size. Leaves with diameters well in excess of 120 cm (4 ft) are commonplace, with a spread of 3 m × 3 m (10 ft × 10 ft) on a mature plant.The largest on record had leaves up to eleven feet (3.3 meters) in width. The underside of the leaf and the whole stalk have spikes on them. In early summer it bears tiny red-green, dimerous flowers in conical branched panicles, followed by small, spherical fruit. Like most gunneras, it has a symbiotic relationship with certain blue-green algae which provide nitrogen by fixation.

Despite the common name "giant rhubarb" it is not closely related to true rhubarb. It was named after a Norwegian bishop and naturalist Johan Ernst Gunnerus, who also named and published a description about the basking shark.

Distribution

Gunnera manicata is native to the Serra do Mar mountains of coastal Santa Catarina and Rio Grande do Sul states, Brazil, where it is used in traditional medicine for sexually transmitted diseases.
