Ranunculus amphitrichus (formerly known as R. inundatus & R.
(River Buttercup) is a native aquatic species that grows in
still or slow moving, shallow fresh water ponds and streams
throughout Tasmania. The plant forms rosettes that are joined by
stolons, and the leaves rise above these with the blades floating on
the surface or in the water column. The leaves often have long
petioles (to 15cm) and the blades are round in outline, but deeply
divided into narrow lobes. The flowers are golden yellow and 10-15mm
