Notes. – Lejeunea flava is widely distributed in tropical and warm-temperate regions of the world and distinguished by ovate-oblong leaves with rounded tips, leaf cells with conspicuous trigones, ± longer than wide underleaves with a cordate base, and gynoecia frequently two in a row on short branches (e.g., SCHUSTER, 1980). Stephani’s description of Taxilejeunea tenuiplica adds another name to the long list of synonyms of L. flava.
