Weda, a new genus of Euphorbiaceae


Material collected during an environmental impact study for a proposed nickel mine along Weda Bay on Halmahera in the North Moluccas of Indonesia revealed one unknown Euphorbiaceae with a very unique combination of characteristics. Based on the characteristics and DNA barcoding it appears that this plant has a very unique position within the Euphorbiaceae and is therefore described as a new genus and new species. Research in the Naturalis geology lab revealed that it is not accumulating nickel in its leaves, as expected, but manganese.
