Erythrophysa transvaalensis, commonly the Transvaal red balloon or bushveld red balloon and in Afrikaans the bosveldrooiklapperbos (bushveld red cracker-bush), is a large shrub or small tree occasionally growing to a height of 5 m (SA Tree List No. 436.2). It probably grows from tuberous roots.
The plant branches from the base or slightly higher up. The bark on the slender, brittle stems is red-brown, smooth and shiny.
The tree occurs in North West, Limpopo and western Gauteng; also in small parts of Zimbabwe and Botswana. The habitat is stony slopes and hills, often near boulders, where it may receive some protection from fire.
This is a protected plant in South Africa, although it is not considered to be threatened in its habitat early in the twenty first century (Coates Palgrave, 2002; www.plantzafrica.com; www.redlist.sanbi.org).
