Flora of St Helena
The flora of Saint Helena, an isolated island in the South Atlantic Ocean, is exceptional in its high level of endemism and the severe threats facing the survival of the flora. In phytogeography, it is in the phytochorion St. Helena and Ascension Region of the African Subkingdom, in the Paleotropical Kingdom.
==Endemic and introduced flora==
The endemic plants of Saint Helena include many notable "insular arborescent Asteraceae", that is, members of the daisy family which have evolved a shrubby or tree-like habit on islands. Other notable endemics include the closely related St Helena redwood (''Trochetiopsis erythroxylon'') and St Helena dwarf ebony (''Trochetiopsis ebenus''). These are unrelated to the redwood trees of California or to the ebony trees of commerce, being instead in the Mallow family (Malvaceae).
