--><p><i>Jaffueliobryum</i> is distributed in cold to hot and arid regions, and usually is found on calcareous rock. It appears to be closest to <i>Coscinodon</i>, from which it differs by the broader, less strongly keeled, mostly 1-stratose leaves, strictly autoicous-cryptoicous sexuality, and calciphilous ecology. The third species, J. arsenei (Thériot) Thériot, larger than our species, is endemic to Mexico and is characterized by a long-rostrate operculum and an exserted capsule.</p>
