(Pandanaceae; Freycinetoideae) from Siberut Island, off the western coast of Sumatra, is described as Freycinetia siberutensis A.P. Keim, Witono, O. Efendy, R.H.B. Setiarto, H.I.P. Utaminingrum, and L.A. Bakti. This species is characterized by its racemose infructescence, narrow lanceolate leaves with serrulate margins, and slender axillary spikes bearing densely arranged berries. The discovery of F. siberutensis adds to the floristic uniqueness of the Mentawai Islands and provides new insights into the diversification of Freycinetia in western Malesia.
