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]

Range and habitat

It occurs in the African tropics and subtropics from coastal elevations to 900 m above sea level.[4] Its range extends westwards up the Zambezi Valley.[5]

They are found in coastal, riverine and evergreen forests or woodland, and in miombo woodlands, while a few are cultivated in parks.[5] They prefer deep sandy soil and often start life as a strangler.[6][7] 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.[7] 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 are cauliflorous, growing on the characteristic wart-like, leafless branchlets on the trunk and main branches (i.e. old wood).[6]

F. chirindensis of the forests of southeastern Zimbabwe and adjacent Mozambique is similar, but has the leaves more oval, often has buttress roots,[6] and bears the small (1.5 cm) figs in stalked pairs on second year branches.[1]

Subspecies and status

  • Ficus s. subsp. sansibarica – East Africa: southern Kenya, Tanzania, Malawi, Zambia, Zimbabwe, Mozambique, South Africa, Swaziland
  • F. s. subsp. macrosperma (Warb. ex Mildbr. & Burret) C.C.Berg – West and Central Africa

The species is deemed critically endangered in Swaziland, where most are located in proposed sugar cane expansion areas near Sihoye.[8] On Inhaca Island however, it is held sacred by most communities, and is scrupulously protected.[3]
