Description

Lysimachia mauritiana is a species of flowering plant in the primrose family Primulaceae. It is native to eastern Asia, where it is widespread in coastal areas. Areas it is native to include China, Japan, Korea, Taiwan, the Philippines, and various islands in the Indian and Pacific Ocean. It is considered to be a common species in Japan. Its natural habitat is along beaches and maritime rock crevices. It is a biennial, growing to 50 cm tall. It has fleshy spathulate to obovate leaves. It produces white terminal racemes of flowers in late spring and early summer. Lysimachia is a genus consisting of 193 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. 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, a king of ancient Sicily, who is said to have calmed a mad ox by feeding it a member of the genus. 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. 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. Several fossil seeds of Lysimachia sp. have been described from middle Miocene strata of the Fasterholt area near Silkeborg in Central Jutland, Denmark. †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.
