Didymocheton alliaceus is a species of flowering plant in the mahogany family, Meliaceae. It is a tree native to the tropical Pacific islands, ranging from the Solomon Islands to the Caroline Islands, Vanuatu, Fiji, Wallis and Futuna, Niue, Tonga, and the Samoan Islands. It is most closely related to Didymocheton mollissimus of Malesia and mainland Southeast Asia, D. mollis of the Bismarck Archipelago, New Guinea, and Sulawesi, and D. muelleri of northeastern Australia.[1]
The species was first described as Trichilia alliacea by Georg Forster in 1786. It was reclassified as Didymocheton alliaceus in 2021.[1]
