Ranunculus auricomus; The Goldilocks buttercup is quite rare on Iceland. It is only found in coastal regions scattered in the east and some localities in the north and north-west. It can be easily overlooked because it resembles the Meadow Buttercup. The leaves though are differently shaped: In the Meadow Buttecup both the basal and first few stem leaves are rather deep-incised hand-shaped blades. In the Goldilocks Buttercup they vary from round non-incised shaped leaf-blades to linearly disected leaves.
A note on the two photo's I took of this species in 2011: they where photographed on the same locality, being a large rock-hollow whithin a small waterfall. I immediately sensed that this buttercup was different.... If anyone is interested I can give the GPS data of this locality
It is a member of the buttercup family (Ranunculaceae). The Icelandic name of this species is Sifjarsóley.
