Those two are Hydnora
africana from Cornel's Kopf.
These are from outside Rosh
This member of the Hydnoraceae
family was described by Carl Peter Thunberg in 1775. It is found in
Namibia and South Africa, growing on the roots of Euphorbia. The
parasite attaches itself to Euphorbia roots 5-15cm below ground, but
will not harm the host. It is rarely encountered, as it exposes only
its rather bizarre-looking dark red flower five to eight centimetres
above the ground.
