Abstract
Peninsular Malaysian Impatiens foxworthyi M.R.Hend. is distinct from the Thai I. opinata Craib. Three new Impatiens species are described: Impatiens glaricola Kiew with purple flowers, Impatiens chikuensis Kiew with pale yellow flowers, and Impatiens vinosa Kiew with deep red flowers. While Impatiens foxworthyi is widespread on karst limestone in Kelantan and Pahang, the three new species are narrowly endemic to Kelantan limestone and are critically endangered.
