Hello, Here are two different flowers with spiny leaves found in Namibia. I have previously seen a similar one to the white one in the south African Kalahari. I thought the ID would be easy because of the leaves but haven't found yet the species. Thanks for your help Cheers
Thanks Tyrlych. For #2 : I think I might have found have found a name in one of my books at at place I hadn't looked before. So it looks to me as Codon sp and particularly be codon schenckii
