This is Welwitschia mirablis, the only member of the Welwitschiaceae family. It is found only in Namibia and Angola, in the Namib desert.
What makes this rather unattractive plant special? First, they are extremely long-lived. It’s thought that some specimens might be over 2000 years old. Second, they absorb the bulk of their water from fog. Specimens have special structures on their leaves which allow them to absorb moisture from desert morning fogs.
