St. Helena Olive

"Previously known from localised subpopulations on the highest parts of the eastern central ridge. N. elliptica became noticeably rare in the nineteenth century, when the subpopulation was recorded as consisting of only 12 to 15 trees on the northern side of Diana's Peak, after a time this subpopulation was thought to be extinct. In 1977 a single tree was discovered on a precipitous cliff near Diana's Peak, this was reported to have died in 1994. . . . The last known tree surviving in the wild died in 1994 and the only known plant still in cultivation died in December 2003. No other live material (plants, seeds or tissues) remains in local or international collections. . . . The threat to this species was loss of habitat through felling for timber and to make way for plantations."
