Prostrate, straggling or clumping shrub, to 0.5 m tall, to c. 1.2 m across. Leaves usually ovate to oblong in gross outline, 2–18 cm long, 20–60 mm wide, pinnatifid to pinnatipartite or toothed or rarely entire; primary lobes 2–21, entire to 5-fid; ultimate lobes triangular to narrowly ovate, 0.5–3 cm long, 0.2–1.5 cm wide, sometimes pungent; margins flat to shortly recurved; lower surface with an open indumentum of ascending, rarely closely appressed curved to curled hairs. Unit conflorescence erect to decurved, secund; floral rachis 35–60 mm long. Flower colour: perianth light green to yellow outside, purplish to black inside; style dull yellow to pale or dark pink with a red or green tip. Perianth loosely tomentose to villous outside. Pistil 12–16 mm long; ovary stipitate; style glabrous. Follicle 10–12 mm long, subsericeous to subvillous. Fig. 4D–F.

Vic.: c. 15 km S of Castlemaine P.O., A.C.Beauglehole 50094 (MEL, NSW); between Malmesbury and Glenluce, 20 Sept. 1961, M.E.Phillips CBG005188 (CANB); Holcombe Parish c. 3.2 km N of Glenlyon on upper Loddon R., 18 July 1937, J.H.Willis (MEL).

This species is recognised as 'Rare' in J.D.Briggs & J.H.Leigh, Rare or Threatened Australian Plants (1995).

There is much variation in leaf form. The 'Fryers Range form' is prostrate with mostly entire or lightly toothed leaves (only occasionally deeply divided) 6–12 cm long. The 'Upper Loddon form' is prostrate with very deeply divided leaves 8–18 cm long. The 'Drummond North form' forms rhizomatous clumps up to 50 cm tall, with leaves small (4–7 cm long), ovate to rhomboid, and sparingly toothed.

Distinguished by its larger floral bracts (5–8 (–10.5) mm long, usually persistent to anthesis, 3–5 mm wide) from most similar species, especially G. bedggoodiana (2–3 mm long, 3–4 mm wide) and G. repens (0.7–2 mm long, 0.2–2.2 mm wide).
