What is "lellingeria"

Lellingeria is a genus of ferns in the family Polypodiaceae. It is one of the grammitids, a clade within Polypodiaceae that has not been ranked as a subfamily or tribe because the phylogeny of Polypodiaceae is not well understood.

Approximately 70 species of Lellingeria are known. They are native to tropical areas of Madagascar, Africa, the Americas, and Pacific Islands. None are known in cultivation. Lellingeria was named for the American pteridologist David Lellinger.
