A woody perennial herb forming tight mats 1-3 cm thick, in patches up to ca. 1 m wide. Rhizomes packed together, ± horizontal and ascending at tips, obscured by crowded leaves; branches single or 2-3 clustered and diverging, at intervals of 0.5-3.0 cm; living leaves closely imbricate on apical ca. 0.5 cm of each stem; lower parts of stems covered with persistent dead leaves. No short shoots. Roots issuing from lower parts of stems, slender but becoming subwoody, up to 0.5 mm diam. Leaves sessile, palmately divided, curved around stem, 4-6 × 4-5mm; blade ca. 3 mm long, crescent shaped, coriaceous, dark green, with scattered short hairs; lobes us. 7, linear, subterete, in a half-circle with central lobes above shorter lateral lobes, acute to acuminate, cut to top of broad leaf base.
