In cross section suborbicular in outline, 62.5-85.0 µm, 4 cells across the diameter; cortical cells 7, subquadrangular, 17.5- 27.5 × 12.5-25.0 µm; medullary cells 3, rectangular-polygonal, 12.5-20.0 × 10.0-15.0 µm; ventral merophyte 1-2 cells wide. Rhizoids numerous, fasciculate at base of underleaves.
Leaves
Contiguous-distant, obliquely-widely spreading; leaf lobes oblong-obovate, 0.8-1.1 mm long, 0.48-0.68 mm wide, dorsal margin arched, ventral margin straight except near apex, margin entire; marginal leaf cells towards apex subquadraterectangular, 15.0-32.5 × 12.5-20.0 µm; median leaf cells hexagonal-polygonal, 20.0-35.0 × 15.0-25.0 µm; basal leaf cells slightly elongated, hexagonal-polygonal, 30.0-55.0 × 15.0-35.0 µm; cells with cordate-nodulose trigones, intermediate thickenings 1-2 per cell wall; cuticle smooth; leaf lobules tubular, as long as lobe, slightly wider toward sac, lateral margin usually incurved, sac small inflated at middle, rounded at apex, margin entire, surface smooth, valve elliptical-ligulate, 110.0-127.5 × 75.0-82.5 µm, with 11-15 median cells surrounded by a ring of 20-25 hyaline cells.
