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.
Acanthaceae Acanthaceae is a family (the acanthus family) of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are tropical herbs, shrubs, or twining vines; some are epiphytes. Only a few species are distributed in temperate regions. The four main centres of distribution are Indonesia and Malaysia, Africa, Brazil, and Central America. The representatives of the family can be found in nearly every habitat, including dense or open forests, scrublands, wet fields and valleys, sea coast and marine areas, swamps, and mangrove forests.
