The familiar and widespread buttercup of gardens throughout Northern Europe (and introduced elsewhere) is the creeping buttercup Ranunculus repens, which has extremely tough and tenacious roots. Two other species are also widespread, the bulbous buttercup Ranunculus bulbosus and the much taller meadow buttercup Ranunculus acris.
Leefructus mirus shows fully developed leaves; stem and flower that are very similar in structure to those of the modern buttercups. The fossil is dated to 125 Mya ( million years old ) and it not only proves that Ranunculales is an ancient group of eudicots but demonstrates that the whole angiosperm clade may be older than expected.
The flowers are golden yellow, glossy, and 2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 4 in) diameter, usually with five petals, and the flower stem is finely grooved. The gloss is caused by the smooth upper surface of the petal that acts like a mirror; the gloss aids in attracting pollinating insects and thermoregulation of the flower's reproductive organs.
