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.
Cistaceae The Cistaceae are a small family of plants (rock-rose or rock rose family) known for their beautiful shrubs, which are profusely covered by flowers at the time of blossom. This family consists of about 170(-200) species in nine genera that are not very distinct, distributed primarily in the temperate areas of Europe and the Mediterranean basin, but also found in North America; a limited number of species are found in South America. Most Cistaceae are subshrubs and low shrubs, and some are herbaceous. They prefer dry and sunny habitats. Cistaceae grow well on poor soils, and many of them are cultivated in gardens.
