Abstract

In Peninsular Malaysia, Coleus is represented by five species. Two, C. hairulii Kiew and C. rafidahiae Kiew, are new species. Both are narrowly endemic and restricted to limestone hills as is C. kunstleri (Prain) A.J.Paton. All three are Critically Endangered. Coleus scutellarioides (L.) Benth., although widespread, is probably not indigenous. It is also a common ornamental, while C. monostachyus (P.Beauv.) A.J.Paton is a recent introduction that has spread rapidly and threatens to become a troublesome weed.
