Christella

Christella is a genus of around 70-80 species of ferns in the subfamily Thelypteridoideae of the family Thelypteridaceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[3][2] Other sources sink Christella into a very broadly defined genus Thelypteris.[4] The genus was named after Konrad H. Christ, a Swiss botanist.[5][6] The distribution of these plants is mostly in the tropics and sub tropical areas.[7] An Australian example is C. dentata.[8]
