One of the most unusual desert plants is Welwitschia. Unfortunately, I didn't see it as it grows only in the northernmost part of the Namib-Naukluft park which we didn't visit. The oldest specimen are known to have been growing for 2000 years and the 'middle-aged' are about 1000 years old. The plant is not a beauty - its two long leaves darkened by the sun and torn by the wind lie twisted around the cork-like stem. The plant takes most of the needed moisture from condensed fog and the pores in the leaves trap it and 'water' the sand below from where the moisture goes to the roots.
Another amazing plant growing in the dunes of Sossusvlei is a !nara melon. It has no leaves but stems growing along the ground that absorb moisture from the morning fog. Its root system is very well developed and it grows to 40metres down in order to reach water deep under the dunes. The stems can die out in case of the lack of moisture but the plant can survive and bear fruit which is a good source of liquid in dry periods.
Besides !nara melons the Namib is home to many species of succulents and lichens.
