Dictyosperma is a genus of flowering plant in the palm family found in the Mascarene Islands in the Indian Ocean. It contains only one species. The ringed trunks are solitary with a slight bulge at the base, occasionally reaching up to 12 m in height. The leaves are borne on short petioles; the arching leaflets are pointed at the apice, dark green in color, and emerge from the rachis in a single plane. On flowering, they produce up to six inflorescences which ring the trunk below the crownshaft, branched to one order, with white to yellow flowers. The ovoid fruit ripen to purple or black in color, containing one brown, ellipsoidal seed.
