Radula aneurismalis

Yellow-green, forming mats or interspersed among other bryophytes, dioicous. Specialised asexual propagules absent. Leaves all of a similar form and showing continuity in size or some branches composed entirely of much smaller and differentiated microphyll leaves, sometimes entire plant composed of these leaves. Microphyll leaves ovate, with lobule to c. 0.8 of lobe area, 175–275 μm long, 150–350 μm wide, remote to imbricate; lobe entire or crenulate; lobule rectangular, 150–250 μm long, 100–150 μm wide, attached to lobe by curving and strongly inflated keel that continues seamlessly the curve of adjacent lobe margin, with rounded or acute apex sometimes projecting beyond lobe margin, often with a free margin that extends over the ventral branch surface. Normal leaves when present elliptic, oblong or ovate, 475–1200 μm long, 425–1000 μm wide, rounded at apex, imbricate, inserted at dorsal mid-line leaving no continuous row of cells uninterrupted by leaf insertions, attached to lobule by curved and strongly inflated keel; lobe margin entire or crenulate, not descending below the level of the keel and not forming a notch at intersection, but instead seamlessly continuing the curve of the keel; lobule truncate-ovate to rectangular, 1/5–1/3 of lobe area on leading shoot, 275–650 μm long, 150–325 μm wide, rounded at each corner of the free margin and usually scalloped between or occasionally straight, fused along stem and so not extending over ventral stem surface. Leaf lobe cells oblong, rounded-quadrate or rounded-polygonal, not forming a vitta, 12–25 μm long, 12–18 μm wide, thin-walled, with distinct concave trigones, smooth, with a single oil body; oil bodies light brown, botryoidal. Perianth 1500–2800 μm long, 900–1175 μm wide.
