Are Cyrtanthus and Fouquieria plants in the same family?
Cyrtanthus Cyrtanthus is a genus of perennial, herbaceous and bulbous plants in the family Amaryllidaceae, subfamily Amaryllidoideae.
Cyrtomium Cyrtomium is a genus of about 15-20 species of ferns in the family Dryopteridaceae, native to Asia, Africa (including Madagascar), and the Pacific Ocean islands (Hawaii). It is very closely related to the genus "Polystichum", with recent research suggesting it should be included within it (Little & Barrington).
