Montia fontana, blinks is a herbaceous annual to perennial plant that grows in freshwater springs in upland regions, and in seasonally damp acid grassland in the lowlands. It is widespread throughout the world, except in southern Asia. It is rather variable in morphology, which is reflected in a complex history of taxonomy. Currently, there are three accepted subspecies which are defined largely by the appearance of the seedcoat. It is edible and consumed as a salad in some areas, but is otherwise of minimal economic impact. Because of its association with clean water habitats, it is often viewed as a species of conservation value.

It is rare and endangered throughout its range, and is considered to be an indicator of favourable environmental conditions.
Ranunculus baudotii, brackish water-crowfoot, is a flowering plant in the Ranunculaceae. As the name suggests, it tends to grow near the sea, typically in pools and ditches in coastal marshes that are slightly salty due to sea spray. It can also be found inland where there is some saline influence. It is not edible and has economic uses, but it is generally valued as a plant of conservation interest and an indicator of less agriculturally improved habitat.
Ranunculus hederaceus is a flowering plant in the family Ranunculaceae.
