Euphorbia dregeana dry seed capsules

Euphorbia dregeana is commonly called elephant’s bush and dikboud (thick buttock) in Afrikaans. The plant exudes the characteristic white Euphorbia latex, sometimes called wolves’ milk.

The flowers are pale yellow, two rounded petal-like lobes encircling the emerging, six-sectioned fruit capsule. The capsule turns red when developed and brown later when it dries.

A rare root parasitic angiosperm, Hydnora triceps, lives on E. dregeana plants exclusively (Wikipedia).
