Hello Steve,
the flowers and your description of the leaves sounds that it could be a plant similar to the Haemanthus species from near Lüderitz.
Some say this is a form of coccineus with untypical leaves. Haemanthus coccineus is very variable, the color of the bracts can be coral red or also brilliant red. The bracts can be thin or waxy, the number of the bracts is also very variable, some plants have only 4-5 bracts, others 12.
So it´s not so easy with the ID
I try to find photos from the leaves of my spec. Lüderitz on my phone
Best wishes
Bernie
