Ranunculaceae
Buttercup Family

The Ranunculaceae is a large family of the cooler temperate zones, particularly in the northern hemisphere. Most members are annual or perennial herbs, but Clematis is a woody vine. They generally have alternate leaves, usually compound or deeply divided (except Caltha). The flowers are usually radially symmetric, but Delphinium and Aconitum are bilaterally symmetric. Each flower typically has many spirally-arranged stamens and several-many distinct carpels. Flowers often (but not always) have no petals and have showy sepals instead. There are many important ornamentals in the Ranunculaceae including Aconitum (monkshood), Anemone, Aquilegia (columbine), Delphinium (larkspur), Helleborus, and Ranunculus (buttercup).
