Woody climbers (Tas.) or trees, shrubs or rarely herbs. Leaves exstipulate, opposite or rarely alternate, usually pinnately compound; terminal leaflet sometimes forming a tendril (not in Tas.). Inflorescence usually a panicle or sometimes flowers solitary in axils. Flowers often showy, often bracteate, bisexual, zygomorphic; receptacle hypogynous. Calyx tubular or campanulate, 5-lobed. Corolla campanulate or funnel-shaped, 5-lobed, sometimes 2-lipped. Stamens epipetalous, typically 4 and didynamous with a staminode in place of a fifth posterior stamen; anthers bilobed, the lobes widely divergent, dehiscing longitudinally. Disc usually present, nectar-secreting. Carpels 2; ovary superior, typically bilocular with axile placentation or sometimes unilocular with 2 parietal placentae; ovules numerous; style filiform with 2 short stigmatic lobes. Fruit a capsule, often elongated, opening by 2 valves, or fruit fleshy and indehiscent (not in Tas.). Seeds numerous, usually flattened and winged, without endosperm.
A family of about 120 genera and 800 species found mainly in tropical areas, especially South America. 10 genera and 17 species in Australia. Bignoniaceae are placed in the Lamiales. The family contains a number of very showy plants cultivated for their considerable ornamental value and includes such genera as Bignonia L., Campsis Lour. (Trumpet Creeper), Jacaranda Juss., Tecomaria (Endl.) Spach (Cape Honeysuckle) and Pandorea (Endl.) Spach (Wonga Vine).

Tas. (FLI); also NT, SA, Qld, NSW, Vic. Localised and rare on Flinders Island where recorded from two localities. Found in gullies and wet sclerophyll forest. Listed as Rare under the Tasmanian Threatened Species Protection Act 1995. Numerous horticultural varieties and cultivars exist and are widely planted in Tasmanian gardens. Pandorea pandorana subsp. austrocaledonica (Bureau) P.S.Green is confined to Lord Howe Island, New Caledonia and Vanuatu. It differs from P. pandorana subsp. pandorana in the margins of the leaflets being bluntly serrated.
