Myrsine knudsenii, the Kokee colicwood, is a species of tree in the primrose family. It is endemic to the island of Kauai in Hawaii. It is threatened by habitat loss.
This is a shrub or tree growing up to 4.5 meters tall with flowers occurring in clusters along the branches.[1] It grows in moist forests dominated by Acacia koa, Metrosideros polymorpha, and Dicranopteris linearis. It probably once occurred in several other types of ecosystem.[2]
There are three populations left, for a total of about 30 trees. It was federally listed as an endangered species of the United States in 2010.[2]
