The Knobbly fig (Ficus sansibarica) is an African species of cauliflorous fig. It is named after Zanzibar, where Franz Stuhlmann discovered it in 1889.[3] They regularly reach 10 m, but may grow up to 40 m tall as forest stranglers.[1] It occurs in the tropics and subtropics from coastal elevations to 900 m above sea level.[4] They prefer deep sandy soil and often start life as a strangler.[5][6] The pollinating wasp is Courtella armata.[4]

Description

The light grey bark is fairly smooth, though lumpy and folded.[1] The smooth leaves are up to 13 cm long and oblong-obovate.[6] They have parallel sides and are carried on slender petioles.[1]

The large (up to 5 cm), bitter-tasting figs appear in groups of 2 or 3 during the summer months.[1] They grow on the characteristic wart-like, leafless branchlets on the trunk and main branches (i.e. old wood).[5]

F. chirindensis of the forests of southeastern Zimbabwe and adjacent Mozambique is similar, but has the leaves more oval, often has buttress roots,[5] and bears the small (1.5 cm) figs in stalked pairs on second year branches.[1]

Races and status

The species is deemed critically endangered in Swaziland, where most are located in proposed sugar cane expansion areas near Sihoye.[7] On Inhaca Island however, it is held sacred by most communities, and is scrupulously protected.[3]
