fern genus "Todea" is known from only two living species. "Todea barbara " L., known as the king fern, is native to South Africa, New Zealand, and Australia while "Todea papuana " H. is known only fromPapua New Guinea . Species in the genus "Todea", as "Leptopteris ", are distinct from other inOsmundaceae in thatsporangia are born on laminar pinnules.So far the fossil record of the genus "Todea" consists only of the permineralized rhizome "T. tidwellii" from the Lower
Cretaceous ofVancouver Island , Canada.References
