Lasianthus tomentosus is a species of plant in the genus Lasianthus within the family Rubiaceae. It is found in Thailand, Java, Sulawesi and New Guinea.[1] It is possibly threatened by habitat loss. Its conservation status is uncertain because of the difficulty of identifying it. Several botanical works have mistakenly described Lasianthus trichophlebus, var. latifolius as Lasianthus tomentosus.[2]
