Tetraena stapffii

Zygophyllum stapffii, synonym Tetraena stapffii, (Afrikaans: daalderplant, English: dollar bush) is a species of flowering bush endemic to Namibia. As of January 2025, the specific epithet was sometimes spelt with a single f, i.e. stapfii, but the International Plant Names Index spells it with double f.
