Studies in Malesian Gentianaceae, VI. A revision of Utania in the Malay Peninsula with two new species

Background – Utania is a resurrected name for a monophyletic group previously placed as Fagraea section Racemosae, part of the Fagraea taxonomic complex, which currently includes five recognised genera. Methods – A revision of the genus in the Malay Peninsula was carried out using conventional methods of herbarium taxonomy. The specimen holdings of the K, KEP, KLU, L and SING herbaria were consulted. Results – Six species are recognised for Utania in the Malay Peninsula, including two new species, U. austromalayensis and U. nervosa . Three new combinations are made: U. maingayi, U. peninsularis and U. racemosa, the last for a species of Indo-China, Thailand, the Malay Peninsula and Sumatra, which does not extend to Borneo and eastwards.
