The Knobbly fig (Ficus sansibarica) is an African species of cauliflorous fig. It is named after Zanzibar, where Franz Stuhlmann discovered it in 1889. They often begin life as epiphytes, which assume a strangling habit as they develop. They regularly reach 10 m, but may grow up to 40 m tall as forest stranglers.
The raw figs are used for food, and are locally believed to promote fertility. Stems are torn apart to obtain fibers for basket weaving. Locally it is also deemed sacred.
