The genus Cyrtandra (Gesneriaceae) in peninsular Malaysia and Singapore

Nine species of Cyrtandra (Gesneriaceae) are recognized in Peninsular Malaysia. Three (C. cupulata, C. pendula and C. wallichii) are common and occur more or less throughout the area; C. pendula is also recorded from Singapore. Four (C. dispar, C. gimlettei, C. patula and C. suffruticosa) have more restricted distributions, and two (C. lanceolata and C. stonei) are local endemics. Three species and one variety originally described by Ridley are here reduced to synonymy: C. barbata (=C. cupulata), C. falcata (=C. suffruticosa) and C. rotundifolia (=C. pendula), and C. cupulata var. minor (=C. cupulata). Keys for fieldwork and herbarium use are presented and general information is provided. The appendix by M.H. Bokhari contains descriptions of leaf anatomy for eight of the nine species recognized and a key based on anatomical characters.
