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.

silène de france

<em>Silene gallica</em>, commonly known as the common catchfly, is a plant species that was historically distributed across Africa, Asia, Europe, the Americas, and Oceania. It typically occupied diverse terrestrial habitats, often found in disturbed ground, arable fields, roadsides, and sandy or rocky soils in temperate and Mediterranean regions. The species is classified as Extinct on the IUCN Red List, indicating that it is no longer known to exist in the wild. Common catchfly belongs to the genus <em>Silene</em> within the family Caryophyllaceae and was a slender annual herb notable for its small, often pink or white flowers and sticky stems. The loss of this species is attributed to habitat degradation, agricultural intensification, and the reduction of traditional farming practices that once maintained the open, disturbed habitats it depended upon. Biological traits such as average lifespan, plant height, and mass of this species remain poorly documented in the scientific literature. Its extinction represents a permanent loss of biodiversity across its formerly wide global range.
