A revision of Codonoboea (Gesneriaceae: Didymocarpoideae) in Thailand

Abstract

The genus Codonoboea Ridl. (Gesneriaceae: Didymocarpoideae: Trichosporeae: Didymocarpinae) is revised for Thailand. Thirteen species are recognised, one of which, Codonoboea poopathii D.J.Middleton, is new to science and three of which, C. dawnii (Kiew) Kiew, C. oreophila Kiew ex C.L.Lim and C. urticoides (A.Weber) Kiew, are new records for Thailand. Didymocarpus reptans Jack is neotypified; D. hispidus Ridl. var. selangorensis Ridl., D. inaequalis Ridl., D. rugosus Ridl. and D. urticifolius Ridl. are lectotypified; and D. hispidus Ridl. is lectotypified in a second step. A key to the species is provided and all species are described.
