Acer oliverianum has a smooth bark that is jade green in colour, with fine white waxy stripes. It grows up to 20 meters wilderness areas of Taiwan but usually only grows to 5 to 8 meters when cultivated. ^[1] It has more or less horizontal branches, and looks similar to Acer palmatum the Japanese Maple.

The leaves are opposite and simple being 6 to 10 cm across, with base truncate or cordate. The leaves are 5-lobed and palmate. The lobes are ovate, the middle lobe having 5 to 8 pairs of lateral veins with minor veins finely reticulate. ^[4]

The flowers are whitish with five purplish sepal. They have five white petals and eight stamen that are longer than the petals. ^[4]

The fruit are glabrous ranging from 2.5 to 3 cm long that spread at a wide angle. ^[4]
