Synonyms: Lobeliaceae APNI*
Description: Annual or perennial herbs, usually with a milky latex.
Leaves alternate, opposite or sometimes whorled, sometimes basal; simple; stipules absent.
Inflorescence cymose, or raceme-like, or flowers solitary in axils of leaf-like bracts or in clusters. Flowers actinomorphic or zygomorphic, bisexual or unisexual and then plants dioecious, usually 5-merous, frequently protandrous. Hypanthium not extended above the inferior ovary. Sepals usually 5, persistent in fruit. Corolla campanulate or rotate, usually 5-lobed, or 1- or 2-lipped, often split on upper surface. Stamens usually 5, free or joined to the corolla basally; anthers and filaments joined in ta tube around the flower; anthers 2-locular, dehiscing and wilting before the flower opens, dehiscence introrse by longitudinal slits; filaments usually expanded and ciliate, persistent in open flowers. Ovary usually inferior, usually 2–5-locular with axile placentation, [sometimes 1-locular with parietal placentation], ovules numerous; style simple, upper part bearing shed pollen, entire or with stigmatic lobes equal in number to the loculi, opening when pollen mostly gone.
Fruit a capsule, dehiscent or somewhat fleshy and indehiscent; seeds numerous.
Distribution and occurrence: World: c. 79 genera, 1900 species, mostly in temperate regions. Australia: 6 genera, 89 species, all States.
