Where found
Grassland on the edges of, and in, swamps, bogs, and depressions subject to flooding. Kosciuszko National Park, the mountains to the north, ACT, and the tablelands south of the ACT.
Notes
Perennial herb usually less than 0.1 m tall, stoloniferous. Flowering stems usually sparsely hairy. Leaves basal, 0.4–2 cm long, to 20 mm wide, hairless or with scattered fine, spreading hairs, dissected into 3-5 segments, the segments linear, 0.5–2 mm wide. Flowers white to cream, 6–17 mm in diameter, with 5-12 petals. Sepals spreading, sometimes hooded. Flowers single. Flowering: Summer. Seeds about 10–20, lens shaped, 2–2.5 mm long, smooth on the sides; beak 0.5-1 mm long, straight to hooked.
Hybrids between Ranunculus millanii and other species (Ranunculus graniticola and Ranunculus collinus) have been given the name Ranunculus x ligulatus. Yellow-flowered forms of this species are thought to be the result of hybridization with these species. Also hybridises with Ranunculus dissectifolius and Ranunculus niphophilus.
All native plants on unleased land in the ACT are protected.
Rare Vic.
