Small glab. ± fleshy herb up to 8 cm. tall; stock short, rather stout; main roots stout. Lvs radical, dark green, coriac., on flattened petioles up to 2.5 cm. long; sheath broad, membr. Lamina crenate, 3-7-foliolate or ternately divided, 1-3 cm. diam., lateral lflts sessile, terminal long- stalked, all ± deeply 3-lobed or -partite.

"Almost exactly as the type but spreading widely by stout, soft, white underground stems, which occasionally arch above the ground. Debris at Blue Lake, Garvie Mts., 1230 m. altitude". Type: BD 59406, Simpson and Thomson, Nov. 1938. The creeping stems are not well shown.
