Notes

Perennial herb to 0.25 m high, hairy, rarely almost hairless. Leaves basal, 0.5–5 cm long, 5–25 mm wide, hairy with fine spreading hairs, compound, with 3–7 leaflets which are further lobed, or or with conspicuous rounded teeth. Flowers yellow, 5–18 mm in diameter, with 5-8 petals. Sepals spreading, slightly rough. Flowering stems unbranched, or branched with up to 5 flowers. Flowers spring-summer. Seeds usually 10–40, 1.5–3 mm long, approximately elliptical, flattish, the sides mildly convex, smooth, tapering gradually into a stout beak 0.5–1 mm long, usually with a hooked or curved down  tip.

Hybridises with Ranunculus dissectifolius and Ranunculus graniticola.

Some small specimens from Kosciuszko National Park, and the Brindabella Range, ACT, appear to be intermediate between Ranunculus pimpinellifolius and Ranunculuus productus.

All native plants on unleased land in the ACT are protected.
