# 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). Other sources sink Christella into a very broadly defined genus Thelypteris. The genus was named after Konrad H. Christ, a Swiss botanist. The distribution of these plants is mostly in the tropics and sub tropical areas. An Australian example is C. dentata.
