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.

cocoa

Cocoa (Theobroma cacao) is a small tropical tree in the family Malvaceae, native to the humid lowland forests of the Amazon basin and Mesoamerica, where it originated in domestication by pre-Columbian civilisations — notably the Maya and Aztec — who consumed fermented cacao beverages in ritual and elite contexts for millennia before European contact. Cultivated commercially across the humid tropics today, primarily in West Africa (Ivory Coast, Ghana, Nigeria), Southeast Asia, and Latin America, it is one of the world's most economically significant crop plants. Growing to 4–10 metres under cultivation, the tree bears distinctive cauliflorous flowers — produced directly on the main trunk and large branches — that are pollinated by tiny midges of the genus Forcipomyia. The large, ribbed pods develop on the trunk and branches, enclosing 20–50 seeds embedded in a sweet white pulp. After harvest, seeds undergo controlled fermentation and drying to develop the complex chemical precursors of chocolate flavour. The seeds contain methylxanthines including theobromine and caffeine, as well as flavonoid antioxidants. Theobroma cacao has not been assessed on the IUCN Red List, though wild populations in its native Amazonian and Mesoamerican range face pressure from deforestation. Commercial production relies on a narrow genetic base and faces growing threats from fungal diseases including witches' broom and frosty pod rot.
