André Joseph Guillaume Henri Kostermans

Kostermans' greatest accolade is the sheer number of plant taxa named after him. The genus Kostermansia, in the Bombacaceae family, stands as a permanent tribute, alongside more than fifty species that carry the epithet kostermansii or similar. That level of recognition reflects how much his work shaped the field.His monographs on Lauraceae, Dipterocarpaceae, and Anacardiaceae remain standard references, and his specimens are housed in major herbaria worldwide, including the Royal Botanic Gardens, Kew. For botanists studying Southeast Asian flora, his name is inseparable from the plants themselves.
