DICOTYLEDON - LAMIALES - ASTERALES - Campanulaceae

Compiled by W.G. Welman

Description :

  • Herbs, undershrubs, or small shrubs, often with milky juice
  • Leaves alternate, rarely opposite or whorled, simple, entire, toothed, lobed or cut, rarely rudimentary; stipules 0
  • Flowers bisexual, regular, in cymes, racemes or panicles or axillary and solitary; bracts present or absent
  • Calyx (3 or 4)5(6-10)-lobed or -partite (calyx tube refers to portion above ovary); lobes equal or unequal, valvate
  • Corolla gamopetalous, 4- or 5-lobed; tube campanulate, cylindric, rarely funnel-shaped, arising at line where calyx becomes free from ovary
  • Stamens as many as corolla lobes and alternating with them, free from or arising in corolla tube; filaments free or connate into a tube, often dilated at base; anthers free but often connivent, 2-thecous, opening lengthwise
  • Ovary inferior, half-superior or rarely superior, (1)2-5(6-10)-locular, with axile placentas, rarely basal or apical, 2-few to many ovules in each locule; style simple, often hidden by connate to connivent stamens; stigmas as many as locules
  • Fruit a capsule or berry, often crowned with persistent calyx, variously dehiscent, rarely indehiscent
  • Seeds often small, smooth or reticulate-rugose

Classification Notes:

  • Lobeliaceae (incl. Cyphiaceae ) is sometimes classified under Campanulaceae in broad sense, which would then consist of three subfamilies, namely Campanuloideae (Flowers ± regular; anthers usually eventually free: all genera of Campanulaceae in strict sense, treated below); Cyphioideae (Flowers irregular; stamens sometimes united, anthers free: Cyphia ); Lobelioideae (Flowers usually irregular; anthers connate: Grammatotheca , Lobelia , Monopsis , Wimmerella (= Laurentia ))

Nomenclature:

  • Campanulaceae
    • Sonder: 530 (1865) in broad sense, excluding Lobeliaceae and Goodeniaceae
    • Thulin: 87 (1983)

Distribution & Notes:

  • Global : Genera ± 35, species ± 700, cosmopolitan, especially in Mediterranean region and southern Africa, relatively few in the African tropics
  • Southern Africa : Genera 12, species ± 260
