Coastal Bladder-nut

Diospyros scabrida, the coastal bladder nut, is a shrub or small tree in the family Ebenaceae native to the coastal forests and thicket vegetation of southern Africa, occurring along the eastern and southern coastal belt of South Africa. The family Ebenaceae is best known for the genus Diospyros, which contains both the commercially important persimmons and the extremely dense, dark ebony timbers. Diospyros scabrida inhabits coastal scrub forest, dune forest, and the margins of afrotemperate and subtropical coastal thicket, occupying the sandy soils and sheltered positions behind foredunes. The species is adapted to the salt-laden air and occasional storm exposure of the coastal zone while remaining protected enough to support woody vegetation. Fruits are small, rounded berries enclosed within the persistent and enlarged calyx lobes, a bladder-like structure that gives the species its common name. These fleshy fruits are eaten by a range of birds and small mammals that disperse the seeds through coastal forest habitats. Diospyros scabrida is assessed as Least Concern by the IUCN, being relatively common in suitable coastal forest and thicket habitats along the KwaZulu-Natal and Eastern Cape coastlines.
