Chroesthes is a small genus that includes three species from Peninsular Malaysia: Chroesthes faizaltahiriana Siti-Munirah sp. nov., C. lanceolata (T. Anderson) B.Hansen and C. longifolia (Wight) B.Hansen. Chroesthes faizaltahiriana, recently discovered in the State of Kelantan, is described and illustrated. This species is similar to the common species C. longifolia, but is distinguished mainly by its inflorescence type, calyx shape and its flowers being bright orange instead of dark purple internally. Chroesthes lanceolata is a new record for Peninsular Malaysia and has only been collected once. Following the IUCN Red List Categories and Criteria, these three species are assessed (national scale assessment) as Critically Endangered (C. faizaltahiriana and C. lanceolata) and Least Concern (C. longifolia).
