DICOTYLEDON - ROSIDAE - ROSIDAE - Araliaceae

Compiled by C.L. Bredenkamp

Description:

  • Trees, shrubs or herbs, sometimes scandent, sometimes dioecious
  • Leaves alternate, very rarely opposite, usually petioled, sometimes sheathed, simple, digitately lobed or once or twice digitately compound; stipules adnate to petioles
  • Flowers regular, bisexual or unisexual, in heads, umbels, spikes, or racemes, with the racemes panicled or umbellate, rarely flowers solitary; bracts and bracteoles usually present
  • Calyx attached to ovary, annular or shortly cupular
  • Petals usually 5, valvate or slightly imbricate
  • Stamens as many as petals, rarely more; anthers ovate or oblong, 2-thecous
  • Disc epigynous, variable
  • Ovary inferior, 2-locular, with a solitary, pendulous ovule in each locule; styles as many as locules, distinct or connate at base
  • Fruit a berry or drupe, or of 2 readily separable mericarps, sometimes flattened and membranous, oil tubes indistinct or absent
  • Seeds sometimes solitary by abortion

Classification Notes:

  • Based on evidence from DNA sequence data (Plunkett, Soltis & Soltis 1997) some genera of the Hydrocotyloideae under Apiaceae (Centella and Hydrocotyle) have been transferred to the Araliaceae

Nomenclature:

  • Sonder: 568 (1862)
  • Strey: 191 (1973)
  • Burtt & Dickinson: 449 (1975)

  • Reyneke & Kok: 317 (1987)
  • Plunkett, Soltis & Soltis: 565 (1997)

Distribution & Notes:

  • Global: Genera 59, species ± 800, fairly cosmopolitan, especially well represented in the Malaysian region
  • Southern Africa: Genera 5, species ± 18, some naturalised
