General/Distribution: A monotypic family with c. 33 species in Asia, Europe and temperate N. America.
Comment/Acknowledgements: Differs from Ranunculaceae in the following characters:

1. Morphological: Extrorse dehiscence of the anthers, the presence of a fleshy disc, the large follicles and arillate seeds.

2. Anatomical: Xylem vessels with scalariform plates (not simple perforations), also the xylem in the stem is not concave or v-shaped but it is rather flat. Large chromosomes of a type not found in Ranunculaceae.
