'''''Tetrapanax papyrifer''''' ('''Tung-tsau''' or '''Rice-paper Plant''') is an evergreen [[shrub]] in the family [[Araliaceae]], the sole species in the genus '''''Tetrapanax'''''. It is [[endemic (ecology)|endemic]] to [[Taiwan]], but also widely cultivated elsewhere in eastern [[Asia]]. It grows to 3-7 m tall, with usually unbranched stems 2 cm diameter bearing a rosette of large [[leaf|leaves]] at the top (superficially similar to a [[Arecaceae|palm]] crown). The leaves are carried on 40-60 cm petioles, the leaf blade orbicular, 30-50 cm across, deeply palmately lobed with 5-11 primary lobes, each lobe usually secondarily lobulate. It spreads extensively by sprouts from the [[root]] system underground.

The [[flower]]s are produced in a large umbel at the apex of the stem, each flower with 4-5 small white petals. The [[fruit]] is a small [[drupe]].

The [[pith]] from the stem is used to make a substance commonly known as [[rice paper]], but more properly termed [[pith paper]].

The species was once included in the genus ''[[Fatsia]]'' as ''Fatsia papyrifera''.
