This plant is found in the forest area in Singapore. In the book titled "The Concise Flora of Singapore Volume 1: Gymnosperms and Dicotyledons by Hsuan Keng published in 1990", it mentioned that this genus name was mis-spelt as Aporosa and the one used in the book is Aporusa (an "u" instead of an "o"). However, in the

International Plant Names Index (IPNI) database, the genus is spelt as Aporosa and Aporusa cannot be found. Furthermore, in the book titled "Systematics of Aporosa (Euphorbiaceae) by Anne Marketta Schot published in 2004", it mentioned that Aporosa was mis-spelt as Aporusa. Hence, I have used Aporosa for this genus.
