Plants very soft-textured and lax. Leaves not at all spinescent, usually quadrifid to 0.5–0.6; lobes lanceolate, broad-based, 8–12(14) cells wide at the base, gradually long-acuminate, ending in a setiform uniseriate row of up to 7–8 elongated (2.8–5:1) cells; lobes usually quite free of cilia; disc (8)9–12(14) cells high, obtrapezoidal, the lateral margins bearing 1–2(3) slender, often long, tapering cilia on each side. Leaves and underleaves near androecia more copiously ciliate-dentate but hardly spinescent. Cells with surface indistinctly papillose. Oil-bodies small for size of cell, (6)7–9(10) per cell, 4.4–4.8 µm and spherical to ellipsoidal and 3.8 × 7.5 to 3.5–5.5 × 4.5–6 µm.
