Flacourtia rukam is a species of flowering plant in the willow family, Salicaceae. It is native to Island Southeast Asia and Melanesia, but has spread into Mainland Southeast Asia, India, and Polynesia.Flacourtia rukam. Flora of China. It is also cultivated for its edible fruit. Common names include rukam, governor's plum, Indian plum, and Indian prune.Lim, T. K. (2013). Flacourtia rukam. Edible Medicinal and Non-Medicinal Plants Volume 5. Springer. pp 776-79.Flacourtia rukam. Pacific Island Ecosystems at Risk (PIER). This species is a tree growing 5 to 15 meters tall. The trunk is lined with thorns up to 10 centimeters long; some cultivated varieties lack thorns. New leaves are red to brown in color. Mature leaves are somewhat oval in shape with toothed edges and up to 16 centimeters long by 7 wide. Racemes of yellow-green male and female flowers occur in the leaf axils. The rounded fruit is about 2 centimeters long and is green, red, or purple in color.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
