Atuna racemosa subsp. racemosa is a subspecies of Atuna racemosa, a plant species in the Chrysobalanaceae family. It is a tree of moderate size, endemic to the Indo-Malaysian and South Pacific areas. It is found growing in such places as Papua New Guinea (kusta), Java, Borneo, Truk Islands (ais) and prolifically on the sea front and in the river valleys of Fiji (makita). This tree once provided the timber for the spars of canoes. The ovoid fruit which this tree bears have been used for medicinal purposes (Truk Is.), or as a glue and varnish in food bowl manufacture (Solomon Is.). Its seeds are a major source of alpha-Parinaric acid, a conjugated polyunsaturated fatty acid with various uses.
