Ficus socrotana is a one of the worlds rarest figs endemic to the island of  Socotra -politically part of Yemen.

Socotra is a  largely uninhabited desert  island approx. 130 km x 30 km wide with small patches of dry  forest in the rocky mountains on the north east coast.

The closest relatives are Ficus vasta of NE Africa and the Arabian Peninsula (considered by some botanists to be con-specific)  and Ficus sycomorus a common savannah fig  throughout East Africa.

Nothing is known about the ecology, but thin flaky bark on fig trees often indicates  a  mutualistic relationship with ants which  feed on the bark and defend the fig tree against leaf eating insects.

Other figs  in the Princess of Wales Conservatory include a Ficus villosa  sourced from Sabah which fruits prolifically, a Ficus hispida which also fruits almost continuously and a Ficus maclellandii periodically mislabelled  as Ficus binnendijkii.
