Lysimachia maritima is a plant species belonging to the family Primulaceae. It was previously called Glaux maritima, the only species in the monotypic genus Glaux.[1] The species has a number of common names, including sea milkwort, sea milkweed, and black saltwort.


Lysimachia maritima has a circumpolar distribution in the northern hemisphere and is native to Europe, central Asia and North America.[2] The species grows mainly in coastal habitats in Europe but also occurs in mesic interior habitats in Asia and North America, in both wet ground and water. It is known from alkaline meadows in desert regions in Utah, at elevations of up to 2600 m (8500 ft).[3]


This plant differs from all other genera of the Primulaceae in having apetalous flowers with a pink, petaloid calyx. It is generally pentamerous both in the calyx and the seed capsule. The leaves are fleshy, simple and opposite.[4]
