Wahlenbergia

Belongs within: Campanuloideae.

Wahlenbergia is a genus of herbs and subshrubs found primarily in the southern temperate regions. Representatives include the Australian W. gracilenta, a slender annual or ephemeral herb with ovate-lanceolate leaves and small flowers (Black & Robertson 1965).

Characters (Black & Robertson 1965): Annual and perennial herbs and undershrubs. Flowers usually blue, pedunculate, often in terminal, dichotomous leafy panicles. Calyx and corolla-lobes mostly 5, rarely 4 or in abnormal flowers 6 to 10; corolla regular, campanulate, seldom almost rotate; stamens 5, free; ovary inferior, 3–5-celled, rarely 2-celled; capsule loculicidal, opening by apical valves surrounded by persistent calyx-teeth.
