About

Lysimachia iniki is a rare species of flowering plant in the family Primulaceae known by the common names Wailua River yellow loosestrife and Wailua River island-loosestrife. It is endemic to Hawaii, where there is only one known occurrence existing on the island of Kauai. The plant was federally listed as an endangered species of the United States in 2010.

This plant was discovered in 1992, shortly after Hurricane Iniki tore a specimen off the tall cliffs above Kauai's Wailua River and dropped bits of it where it could be collected. When analysis revealed it was a new species, it was described to science and named for the hurricane. The Hawaiian word `iniki means "sharp and piercing, as wind or pangs of love."
