Species Description - Monoicous or dioicous. Plants to 3 cm long × 1-3 mm wide, glossy, usually brownish green. Branching Lejeunea-type. Stems 0.07-0.15 mm in diam., in cross section composed of 10-12 thin-walled epidermal cells surrounding 10-55 much smaller medullary cells. Leaves subimbricate, irregularly crisped-subconvoluted when dry, especially the ventral portion of the leaf, dorsal lobe ovate, 0.5-1.8 × 0.3-1.3 mm, apex rounded-obtuse, dorsal margin plane, ventral upcurved, when flattened forming an angle of 110-180° with the keel, margins toothed all around with 7-24 teeth, teeth usually consisting of 1-10 cells, ventral tooth much larger, consisting of up to 30 cells; median cells ca. 20-35 m, with small cordate trigones and l(-2) intermediate thickenings on longer cell walls; oil bodies small, homogeneous, Massula-type, 6-25 per cell. Lobules trapezoid-quadrate to short ovate, ca. 0.2-0.5 long, l/5-l/3× lobe length, keel curved, free margin with 2-4 erect or incurved teeth, teeth 1-3 cells long. Underleaves distant to contiguous, orbicular to transversely ovate, 0.2-0.7 × 0,3-1 mm, (2-)3-5(-7)× stem width, margins usually recurved and weakly to strongly toothed with up to 25 teeth, occasionally entire, bases cordate, folded and seemingly auriculate, the "auricles" rounded or angular, insertion line arched to 0.15-0.3 mm deep. Androecia as in the genus. Gynoecia: bract lobes larger than leaves, the margins toothed with 10-25 teeth; bracteoles obovate-suborbicular, ca. 0.6-0.9 mm long, margins toothed. Perianths with two dentate-ciliate lateral keels and one smooth or slightly dentate ventral keel; beak 2-6 cells long, usually slightly recessed. Sporophyte as in the genus. Vegetative reproduction: cladia occasionally present, basal leaves with acute apex, margins with numerous small teeth.

Discussion
Although the type specimen of Odontolejeunea lunulata is dioicous, the species is more commonly monoicous. Odontolejeunea lunulata is the only species of the genus which may produce monoicous populations; the two other species are strictly dioicous. As pointed out by Teeuwen (1989), the polyoicy of O. lunulata has caused much confusion as to the correct delimitation of the species. Several of the synonyms listed here, e.g., O. tortuosa, O. sieberiana and O. chaerophylla, are mere monoicous forms of the species.

Distribution
Very common throughout tropical America, from sea level up to 3000 m; also in tropical Africa. Odontolejeunea lunulata occurs in primary and disturbed forests and in scrub on living leaves, twigs and on trunks, very rarely on soil. The species is one of the most common epiphyllous liverwort species of tropical America. It is also common on bark and in a submontane rain forest in Bolivia, the author observed that O. lunulata occurred mainly on bark whereas O. rhomalea was common on leaves.
