strophanthus glabre du Gabon

Climbing Oleander, Strophanthus gratus, is a woody liana or climbing shrub in the family Apocynaceae native to tropical West and Central Africa, occurring in rainforest margins, gallery forest, and secondary forest from Senegal to Uganda. The species belongs to a genus celebrated for the cardiac glycosides and arrow poisons produced in the seeds; Strophanthus species were the source of the drug ouabain (g-strophanthin), historically used in cardiac medicine and by African hunters as an arrow poison applied to hunting darts. Climbing Oleander produces large, funnel-shaped flowers with white to pale pink twisted petals and a fringe of elongated lobes at the corolla mouth, borne in terminal cymes that are highly ornamental. The name 'climbing oleander' refers to the superficial resemblance of the flowers to the related Mediterranean oleander (Nerium oleander). The species climbs by twining its stems around supporting vegetation and is occasionally cultivated as an ornamental in tropical gardens. The seeds contain strophanthin and other potent glycosides that affect the cardiac system; all parts of the plant are toxic if ingested. The species is not currently assessed as threatened within its native tropical African range.

coast amaranth

Coast amaranth (Amaranthus pumilus) is an annual herb in the family Amaranthaceae, native to the Atlantic and Gulf coasts of the eastern United States, where it once grew on coastal foredunes, beach strand, and shell-hash substrates above the high tide line from New York south to South Carolina. It is a low-growing, fleshy plant with small, rounded leaves and inconspicuous green flowers typical of the genus. Coast amaranth is assessed as Extinct in the Wild by the IUCN, as it has not been reliably documented from wild populations since the mid-20th century; the last confirmed collections date to the 1960s. The species' decline and likely extinction resulted from intense human pressure on Atlantic coastal habitats through shoreline development, beach stabilisation, vehicular traffic on beaches, and increased storm frequency disrupting pioneer dune vegetation. It is federally listed as Threatened in the United States, though this listing predates confirmed extinction in the wild. A small number of ex-situ accessions may exist in botanical garden collections. Genetic material and seed banking efforts represent the only remaining conservation options for this critically reduced species.
