--><p>Callicostella is characterized by broad and abruptly acuminate leaves with no border. Other distinctive features include the long, tough double costa and the small, isodiametric, firm-walled, 1-papillose laminal cells. The distal leaf margins are strongly serrate, with teeth often 2-fid. Callicostella may also be distinguished from closely related genera by its stem epidermis composed of small, thick-walled cells.</p>
