It has two recognised hypothetical wild ancestors, Garcinia mangostana var. malaccensis and G. mangostana var. borneensis, distributed in the lowland dipterocarp-dominated forests of Sumatra, the Malay Peninsula, and Borneo. The highly similar morphological characters between the cultivated and wild varieties have posed challenges in identification. Additionally, Garcinia penangiana is often mistaken for G. mangostana var. malaccensis, and G. venulosa is regarded as morphologically similar to G. mangostana var. borneensis. In the present study, we conducted morphometric analyses of Garcinia mangostana var. mangostana, G. mangostana var. borneensis, G. mangostana var. malaccensis, G. penangiana and G. venulosa. We assessed the efficacy of morphological characters in combination (vegetative-male flowers-female flowers) in distinguishing the taxa as recognised in the current taxonomy. In our morphometric analyses, we found that Garcinia penangiana and G. venulosa are well delimited and congruent with their current taxonomic designations. A combination of vegetative and male-flower characters provided the most definitive delimitation. We recovered the specific coherence of Garcinia mangostana, but the infraspecific delineations of G. mangostana var. mangostana, G. mangostana var. borneensis and G. mangostana var. malaccensis are not supported. specialized INDE BANGLADESH VIET NAM LAOS CAMBODGE CHINE MALAISIE SUMATERA BORNEO PHILIPPINES 076BOTA04 81 art. 2003 [25 ] 2024 0960-4286 https://www.documentation.ird.fr/hor/fdi:010087974 10.24823/EJB.2024.2003 0960-4286 [F B010087974] https://www.documentation.ird.fr/hor/fdi:010087974 IRD - Base Horizon / Pleins textes 2024-08-23 2025-11-06 fdi:010087974 fre
