Ranunculus longirostris, the longbeak buttercup, [1] is an aquatic plant in the buttercup family.

This species is native to Canada and the United States, where it is widespread. However, it is absent from most of the Southeastern United States. [3] It is found in a diversity of freshwater aquatic habitats, often in streams with slow moving water. [4]

There has been some difficulty in separating this species from the closely related Ranunculus trichophyllus , due in part to the lack of preservation of critical features on herbarium specimens. [5]

Ranunculus hydrocharoides is a species of buttercup known by the common names frogbit buttercup, or frog's-bit buttercup. It is native to western North America, including the southwestern United States and Mexico. It is also known from Guatemala. It is aquatic or semi-aquatic, growing floating in water or in wet land near water. Typical habitat includes marshes, streams, and lakes. Stems are up to 25 centimeters long, prostrate on the ground when terrestrial, or floating when aquatic. The shiny green leaves have heart-shaped or oval blades up to 3 centimeters long which are borne on petioles which may be 15 centimeters in length. Flowers have 5 to 8 shiny yellow petals a few millimeters long with many stamens and pistils at the center. The fruit is an achene borne in a spherical cluster of 9 or more.

It is native to a few areas in western North America, where it is reported from British Columbia, Oregon, and northern California. It is an aquatic plant, growing in various types of shallow-water habitat, including forest ponds and vernal pools. It is an annual herb producing submerged stems 20 to 80 centimeters long which may float at the surface. The blades of the leaves are tiny and divided into threadlike segments. If any leaves develop on stem parts which are exposed to air they are much different in morphology, developing larger, more robust leaves. Flowers have generally 5 petals which are white in color and about half a centimeter long. Many stamens and pistils fill the center of the flower. The fruit is an achene borne in a spherical cluster.
