KIGGELARIACEAE 28 genera, 144 species; pantropical, including Queensland of Australia. Trees or shrubs, sometimes thorny, often with cyanogenic glycosides. Leaves alternate, simple, entire or toothed (but teeth not of salicoid type), pinnately veined or 3- veined from the base. Stipules present or absent. Flowers unisexual or bisexual. Perianth acyclic (sepals and petals spirally arranged and ±indistinguishable) to cyclic, the petals then sometimes more numerous than the sepals. Petals sometimes with an adnate adaxial scale (Erythrospermeae, Kiggelarieae).

KIGGELARIACEAE

• 28 genera, 144 species; pantropical, including Queensland of Australia.

• Trees or shrubs, sometimes thorny, often with cyanogenic glycosides.

• Leaves alternate, simple, entire or toothed (but teeth not of salicoid type), pinnately veined or 3-veined from the base. Stipules present or absent.

• Flowers unisexual or bisexual.

• Perianth acyclic (sepals and petals spirally arranged and ±indistinguishable) to cyclic, the petals then sometimes more numerous than the sepals. Petals sometimes with an adnate adaxial scale (Erythrospermeae, Kiggelarieae).

KIGGELARIACEAE --- cont.

• Stamens 5-numerous, anthers often linear, sometimes dehiscing poricidally, initiation (where studied) centripital or simultaneous.

• Ovary superior, unilocular with parietal placentae.

• Fruit a berry, indehiscent berry (rarely woody), or capsule.
