Harmandia mekongensis is a species of flowering plants. It is the only species in the monotypic genus of Harmandia.[1] In the APG IV system, the genus is placed in the family Olacaceae.[2][1][3]: 9 Other sources place it in the segregate family Aptandraceae.[4]
Its native range is Indo-China to Sumatra, Malay Peninsula and Borneo in western Malesia.[1][3]: 10
Taxonomy
The genus name of Harmandia is in honour of Jules Harmand (1845–1921), a French naval doctor and naturalist, who collected plants in south-east Asia, Japan and present-day Sri Lanka.[5] The Latin specific epithet of mekongensis is named after the Mekong River from where the plant was collected. It was first described and published in Bull. Mens. Soc. Linn. Paris Vol.2 on page 770 in 1889.[1]
