Aster Vine
Solanecio angulatus
Observed along a sunny trail in the Olof Palme Agroforestry Center, Kitale, Kenya. April 2013.
I have only a photo of the leaf. The stiff, partly succulent leaves are sharply lobed, and the lobes are back-swept. This design allows the plant to grow as a vine climbing up and through other shrubs. Vine-like growth among the composites is very rare. With only the leaf, Mark Hyde was able to give me the name! The flower heads are yellow and without rays. They occur in clusters and are small.
This example was found along a wide sunny path in the Taita Hills, Kenya, Africa. 29 May 2017.
