Solenostoma inundatum

Tufts on soil, pale green, yellow-green to brownish or tinged with red or purplish red, dioicous. Stems ascending; branches emerging laterally from stems from near unmodified leaves. Leaves orbicular, ovate or broadly elliptic, 400–800 µm long, 300–910 µm wide, succubous to transverse, arching outwards away from stem, remote to imbricate, weakly decurrent, unistratose, with weakly recurved margins, with rounded or weakly emarginate apices. Leaf cells firm-walled, with distinct trigones, smooth or striolate, in centre toward base oblong, to 55 µm long and 33 µm wide, oblong, rounded-quadrate or elliptic in apical half, 15–35 μm long, 12–26 µm wide, with 4–7 (–8) oil bodies; oil bodies fusiform or ellipsoid, hyaline, finely granular. Rhizoids infrequent and scattered on ventral stem, hyaline or yellowish. Androecia terminal, becoming intercalary, with 4–5 pairs of leaf-like bracts, recurved at the apex, each with 1–2 antheridia. Female bracts broadly elliptic to orbicular, weakly fused with base of perianth, larger than vegetative leaves; bracteoles absent. Perianth appearing disproportionately large for plant, to 2.25 mm long, exserted well beyond bracts, cylindric to narrowly obovoid, terete in base, 3–4-plicate in apical half, crenulate and beaked at mouth. Capsule short-ellipsoid, 2-stratose; spores papillose.
