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 Forest Grape

<em>Rhoicissus tridentata</em> is a woody climbing plant in the family Vitaceae, order Vitales, commonly known as the common forest grape or bushman's grape. The species is classified as Least Concern on the IUCN Red List. <em>Rhoicissus tridentata</em> is native to sub-Saharan Africa, where it typically grows in forest margins, thickets, rocky outcrops, and riverine woodlands. It climbs by means of tendrils, often scrambling over shrubs and into tree canopies. The plant produces small, dark purple to black berries that are edible and have been used as a food source by indigenous communities across its range. Leaves are trifoliate — composed of three leaflets — a feature reflected in the species epithet "tridentata." The roots of this species have been used in traditional medicine in southern Africa for a variety of ailments. Biological traits of this species remain poorly documented in the scientific literature.
