Lysimachia remyi subsp. maxima is a rare species of flowering plant in the family Primulaceae known by the common name Pelekunu Trail yellow loosestrife.[2] It is endemic to Hawaii, where there are only two small populations remaining on the island of Molokai.[3] It is federally listed as an endangered species of the United States.

This is a shrub with sprawling branches lined with leaves growing in clusters of three. The solitary flowers are purple in color.[4] The plant grows only in the wet forests of the Pelekunu Mountains of Molokai. The most recent surveys revealed a total of twenty individuals, ten in each of the two populations.[3]

The plant is threatened by the invasion of introduced species of animals such as feral pigs and feral goats, and plants such as Koster's curse (Clidemia hirta) in its habitat.[3] The plant is vulnerable because of its small numbers; a single event could conceivably cause its extinction.[3]

Officials have released the leaf-eating insect Lius poseidon into the habitat as an agent of biological pest control against Koster's curse. It is too early to determine how successful this effort has been.[3]
