Summary
Atropical family of both Old and New Worlds, though only one or two genera (introductions excluded) occur in both floras. In West Africa, the family is a small one (six genera, nine species) and yields no major economic products. However, its species are commonly seen and are of ecological prominence.
Numerous species have been introduced into West Africa. From the Americas, jacaranda (Jacaranda mimosifolia) and yellow tecoma (Tecoma starts) are often seen, as well as a red tecoma (Tecomaria capensis) from South Africa. This last climbs by twining, and a number of other genera in the family either twine or have claw-like hooks or tendrils (replacing the terminal leaflet), or clasping roots. Bignonia capreolata, introduced from America, has tendrils. Only one West African species, Dinklageodoxa scandens, reported only from Liberian coastal savanna, is a climber (by twining). Anomalous secondary thickening occurs in these species.
In West Africa, members of the family may be recognised by their large, opposite, compound imparipinnate leaves and conspicuous panicle-like cymes of large, brightly coloured zygomorphic flowers, with darker nectar guides, followed by long, slim two-valved capsules with winged seeds.
Flowers .1. 5-part. K(5), 5-toothed or spathaceous, in which case the calyx develops in 1 piece and splits at bud-opening, either down the adaxial side (Markamia, Spathodea) or down the abaxial side (Newbouldia). C(5), 2- lipped, but in Spathodea with well-developed lobes, splitting adaxially. Stamens 4, epipetalous, with apically attached anthers and of 2 different heights. The staminode is adaxial.
