General/Distribution: A small genus of about 6 species, which was previously included in Ranunculus, but seems to be closely related to Oxygraphis or the American genus Cyrtorhyncha. Most or all the species seem to be halophilic and prefer more or less muddy ground. They are widely distributed in Northern, Central and E. Asia and in the extratropical parts of the Americas.
Comment/Acknowledgements: Represented in Pakistan by 1-2 species.
