Giant groundsel - Dendrosenecio kilimanjari
The giant groundsels are an interesting plant genus, only growing on mountain ridges in Africa: D. kilimanjari is only known to grow on Mount Kilimanjaro (Tanzania).
Every species in the Dendrosenecio genus has its own isolated habitat and show signs of adaptation to their own environment; they are a perfect example of Adaptive Speciation. The “flying islands” of these mountain ridges are extremely cold and very dry (since the actually grow above the clouds), so the plants have invested in some adaptations like:
- Natural anti-freeze components
- Thick succulent-like leaves
- Isolation by retaining dead leaves on their stem
