Are Cyrtanthus and Fouquieria plants in the same family?
Fouquieria Fouquieria is a genus of 11 species of desert plants, the sole genus in the family Fouquieriaceae. The genus includes the ocotillo ("F. splendens") and the boojum tree or cirio ("F. columnaris"). They have semisucculent stems with thinner spikes projecting from them, with leaves on the bases spikes. They are unrelated to cacti and do not look much like them; their stems are proportionately thinner than cactus stems and their leaves are larger.
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).
