(old Greek name, applied to some doubtful plant). Datiscaceae. Tall perennial herbs, one of which is sometimes planted in gardens.

Glabrous branching hemp-like plants with pinnately compound or ternately divided alternate leaves, the leaflets or segments lanceolate and usually serrate or toothed: flowers usually dioecious, the staminate fascicled in the axils and short-pedicelled, the pistillate racemose on axillary branchlets; stamens in sterile flower 8-12-25, mostly opposite the calyx-lobes; stamens sometimes present in fertile flowers but few and perhaps alternate with calyx-lobes; ovary 3-angled at top, with 3 styles which are 2-parted: fruit a narrow ribbed many-seeded caps., opening between the styles at the top. - Species 2, one in S. E. Eu. and W. Asia, and the other in Calif, and Mex.; the former is in cult, abroad, requiring no special treatment; prop, by seeds and division.

The family Datiscaceae is placed near Begoniaceae and Cactaceae. It comprises two other genera of tall trees, neither of which is recorded as in cultivation; these are Octomeles, with two species in the Malayan archipelago, and Tetrameles with one species in East India to Java.
