The Saint Helena olive (Nesiota elliptica) is an extinct species of flowering plant. It is the only member of the genus Nesiota. It was endemic to the island of Saint Helena in the South Atlantic Ocean. Despite its name, it is unrelated to the true olive (Olea europaea), but is instead a member of the family Rhamnaceae, the family which contains buckthorns and jujube. The last remaining tree in the wild died in 1994, and the last remaining individual in cultivation died in December 2003, despite conservation efforts. It is thus a prime example of recent plant extinction. The Saint Helena olive belongs to the tribe Phyliceae, which are mostly endemic to Southern Africa.

  • Der St.-Helena-Olivenbaum (Nesiota elliptica) war die einzige Pflanzenart der monotypischen Gattung Nesiota. Trotz des Namens war er nicht näher mit dem Olivenbaum verwandt, sondern gehörte zur Familie der Kreuzdorngewächse (Rhamnaceae). Er war endemisch auf den höchsten Punkten der östlichen Zentralbergkette der Insel St. Helena und gilt seit 2003 als ausgestorben. (de)
  • Nesiota fue un género monotípico de arbusto de la familia Rhamnaceae. Su única especie, el olivo de Santa Elena Nesiota elliptica (Roxb.) Hook.f., fue nativa de las islas Santa Elena, Ascensión y Tristán de Acuña en el Atlántico Sur. El último árbol que quedaba en el medio silvestre murió en 1994, y la única planta que quedaba en cultivo murió en diciembre de 2003, a pesar de los esfuerzos de conservación. Por tanto, es un ejemplo típico de especies y géneros en extinción. (es)

  • Nesiota é um gênero botânico monotípico pertencente à família Rhamnaceae. A sua única espécie Nesiota elliptica, ou oliveira de Santa Helena, pertencente à rica flora nativa da Ilha de Santa Helena, no Oceano Atlântico Sul, extinguiu-se no ano de 2003 após a morte do último exemplar cultivado. Descrita no século XIX, foi julgada extinta em meados do século XX. Um único exemplar selvagem encontrado em 1977, e finalmente morto em 1994, foi utilizado para as frustradas tentativas de salvar a espécie de extinção. (pt)

  • 聖赫勒拿橄欖(學名:Nesiota elliptica)是鼠李科一種已滅絕的有花植物。它們是南大西洋聖赫勒拿島的特有種。雖然它們名叫橄欖,但卻與之沒有關係。野外最後一株於1994年枯萎,而培植的最後一株也於2003年死亡。 (zh)
  • Nesiota elliptica (Engels: Saint Helena olive) is een uitgestorven boom die endemisch was op Sint-Helena. De soort vormde het monotypische geslacht Nesiota binnen de wegedoornfamilie (Rhamnaceae). Het was een tot 4 m hoge boom met vele vertakkingen en een donkerbruine tot zwarte schors. De bladeren waren 5-8 x 2-3,5 cm groot, langwerpig met een omgekrulde top, donkergroen aan de bovenzijde en aan de onderzijde bleker en bedekt met platliggende haren. De roze bloem groeiden in compacte, dichtvertakte bloeiwijzen die niet boven de bladerkroon uitstaken. De vruchten waren harde, houtige, 1-2 cm lange doosvruchten die bij rijpheid openklapten, waarbij driehoekige, glanzende zaden tevoorschijn kwamen. (nl)
