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.

Common Star-apple

<em>Diospyros dichrophylla</em>, commonly known as the common star apple or bladder nut, is a small deciduous tree or shrub in the family Ebenaceae, native to southeastern Africa. This species typically inhabits riverine forests, bushveld margins, rocky hillsides, and scrubby thickets in subtropical and tropical woodland regions. It is distributed across southern and eastern Africa, with populations recorded in South Africa (particularly KwaZulu-Natal and Limpopo), Eswatini, Mozambique, and Zimbabwe. Classified as Least Concern on the IUCN Red List, <em>Diospyros dichrophylla</em> remains relatively widespread within suitable habitats across its range. The species produces small edible fruits that ripen to yellow or orange and are eaten by wildlife including birds and small mammals. The flowers are white and fragrant, and the plant is sometimes cultivated as an ornamental or for its edible fruit. Biological traits such as average lifespan, body dimensions, and dietary specifics remain poorly documented in the scientific literature for this plant species. The common name "star apple" in this context refers to the star-like pattern visible when the fruit is cut in cross-section. The species is ecologically important as a food and shelter resource for local fauna in its southeastern African range.
