Lysimachia ( )Sunset Western Garden Book, 1995:606–607 is a genus consisting of 182 accepted species of flowering plants traditionally classified in the family Primulaceae. Based on a molecular phylogenetic study it was transferred to the family Myrsinaceae, before this family was later merged into the Primulaceae.

Characteristics Lysimachia species often have yellow flowers, and grow vigorously. They tend to grow in damp conditions. Several species within Lysimachia are commonly called loosestrife, although this name is also used for plants within the genus Lythrum. The genus is named in honor of Lysimachus, who is said to have calmed a mad ox by feeding it a member of the genus.Lady Bird Johnson Wildflower Center, Native Plant Information Network (NPIN)

Lysimachia species are used as food plants by the larvae of some butterflies and moths, including the dot moth, grey pug, lime-speck pug, small angle shades, and v-pug.

Specialized pollinators Bees of the genus Macropis are specialized to pollinate oil-producing Lysimachia plants. These bees use exclusively Lysimachia floral oils for building their nests and provisioning cells. Lysimachia floral-specific chemicals are strong attractors for Macropis nuda and Macropis fulvipes bees that are seldom found in other plant genera.

Fossil record Several fossil seeds of Lysimachia sp. have been described from middle Miocene strata of the Fasterholt area near Silkeborg in Central Jutland, Denmark.Angiosperm Fruits and Seeds from the Middle Miocene of Jutland (Denmark) by Else Marie Friis, The Royal Danish Academy of Sciences and Letters 24:3, 1985 †Lysimachia nikitinii seed fossils have been collected from Pliocene strata of south eastern Belarus. The fossils are most similar to seeds of the East Asian Lysimachia davurica.The Pliocene flora of Kholmech, south-eastern Belarus and its correlation with other Pliocene floras of Europe by Felix Yu.
