Family:Lejeuneaceae
Description:Species Description - Plants autoicous, dull brown, leafy shoots 0.9-1.8 mm wide, profusely branched. Stems in cross section 70-165 µm in diameter, medullary cells 9-20, ca. 2-A µm thick, ventral stem cells quadrate to short-rectangular, 20-50 × 20-80 µm, dorsal stem cells variously shaped, 15-50 × 25-65 µm. Flagelliferous branches not seen. Leaves imbricate, leaf lobe ovate, slightly falcate, 270-690 × 430-940 Jim, margins toothed, with 5-8 antical and 0-2 postical teeth, teeth one cell long projecting from a 2-celled base, 10-30 Jim long, apex incurved; median cells leaf lobe rhomboidal to elliptical or subquadrate, 15-35 × 15-50 µm, marginal leaf lobe cells 10-20 × 10-25 µm; ocelli, 20-35 × 35-60 µm, moniliate, (l-)2 per leaf, row 80-115 µm; oil bodies not seen; lobules inflated toward the keel, 0.4-0.5 the length of the leaf lobe, free margin plane, apical tooth sometimes scarcely projecting. Utriculi absent or single at the base of lateral branches. Underleaves entire, 120-320 × 125-280 µm, mostly wider than long, to 2 times the stem width, margins entire and plane. Androecia in spikes of 2-6 bract pairs, 260-750 µm long, bracteole entire, ca 90 × 80 µm. Gynoecia on lateral branches with 1 sterile innovation or on main stems with 1 fertile innovation; bract lobe obovate, margins toothed at the apex; bracteole ovate, 325-380 × 425-480 µm, margins entire, connate at the base with the bracts. Perianth obconic, 350-450 × 520-720 µm, horns bulbous, sometimes appearing laterally compressed, 4 per perianth, 140-250 µm long. Sporophyte not seen.

Discussion:A seldom-collected species, Ceratolejeunea globulifera can be distinguished from C. desciscens by its distant, smaller underleaves always less than twice the stem width. The leaf lobes in C. globulifera are frequently toothed along the antical margin, whereas in C. desciscens the teeth are restricted to the apex. The ocelli are moniliate in both species, but in C. globulifera their number is restricted to two (occasionally one or three), whereas C. desciscens can have up to six ocelli in a row.
