Polyscias flynnii is a tree up to 9 m tall. Leaves are pinnately compound, up to 60 cm long, with reddish-brown hairs on the underside but not on the upper side. Inflorescence is a panicle or umbel hanging from the axils of the leaves, with 10-15 flowers. Flowers are yellow-green, some hermaphroditic (both male and female) but others on the same plant staminate (male only).[6][8]
