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 Ethiopia 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 mislabelled  as Ficus binnendijkii.
