Guioa
Genus of plants
Guioa is a genus of about 70 described species in the maple and lychee family Sapindaceae. It has a wide distribution, ranging from mainland Southeast Asia, through Malesia and Papuasia to eastern Australia and islands of the western Pacific.
Many Guioa species are threatened to varying degrees, as recognised by the International Union for Conservation of Nature (IUCN). Twenty five species have IUCN statuses of either critically endangered, endangered or vulnerable.
The Australian species are known to the logging industry as cedars, though they have no direct relationship with true cedars nor the Australian members of the Meliaceae which are also known as cedars.
