![]() ![]() Small flowered Buttercup ( Ranunculus parviflorus) Pale Hairy Buttercup ( Ranunculus sardous) Large Annual Buttercup ( Ranunculus trilobus) The petals don't overlap.Ĭelery Buttercup ( Ranunculus sceleratus) The beaks of the achenes are less curved and almost erect. Toxicity:Not recorded as toxic in the field.Īustralian Buttercup ( Ranunculus lappaceus) is very similar but does not have long stolons or runners spreading from the base. It can reduce pasture productivity, and may impede water flow in drains. It is not uncommon in weak, poorly drained, pastures. Germination occurs in the Autumn.įlowering times: Seed Biology and Germination:įound in all parts of Tasmania but is somewhat less common in the Midlands.ĭetrimental:It is a species of waste areas and is found particularly along creeks and in roadside ditches. Leaves alternate or radical, trifoliate or pinnate with broad lobes and pale veins. Key Characters:Villous, perennial, land plants Nectar pit at the base.įruit:Achene, smooth, flattened, egg shaped, 3 mm long. Petals - 5, yellow, egg shaped, 10-25 mm long, overlapping. Stoloniferous to several metres long.įlower stem - Erect, reach a height of some 600 mm, while the spreading stems may extend over several metres and cover a considerable area.įlower head:The flowers are axillary carried on long stems.įlowers: Yellow, 20 to 30 mm in diameter. Stems: Much branched, low lying, root at the nodes, hollow, circular in cross section, and hairy. Towards the top of the flowering stems the leaves are reduced in size and have fewer lobes. They have hairs on the upper and lower surface and on the petiole, and usually have the veins distinctly pale in colour and have pale areas on the leaf surface. Stem leaves - Have long petioles and are 100 to 200 mm long. Each segment usually has 3, toothed lobes or is deeply divided. Petiole - 50-180 mm long with papery, clasping, sheathing bases.īlade - Egg to wedge shaped in outline, 15-80 mm long, divided in sets of 3 segments with the central segment on a obvious stalk to being trifoliate. The leaves are initially lobed but, as the plant grows, they become trifoliate or pinnate and much divided. The seedling has a very short hypocotyl and no epicotyl.įirst Leaves:The leaves arise singly, the first being 12 to 16 mm long overall with a petiole about 5 mm long. 8 to 12 mm long overall with a short petiole, and is hairless. ![]() The leaves are usually trifoliate and lobed. ![]() Summary:A perennial herb with creeping, stoloniferous stems and erect flower stems with yellow flowers with overlapping petals. Repens is from the Latin repe meaning to creep referring to the creeping habit of stems.Ĭreeping Buttercup because it has creeping stems and butter yellow, cupped flowers. Ranunculus is Latin for tadpole from the Latin rana meaning frog and may refer to the damp habitats preferred by many species in this genus. ![]()
