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 Marsh Bedstraw

<em>Galium palustre</em>, the common marsh bedstraw, is a scrambling herbaceous plant in the family Rubiaceae, distributed across Europe, North America, and Oceania. It is classified as Least Concern on the IUCN Red List. This species typically grows in wetland habitats including fens, marshes, wet meadows, ditches, and the margins of rivers and ponds, where it climbs through taller vegetation using tiny hooked bristles on its stems and leaves. Common marsh bedstraw produces small, white, four-petalled flowers in loose clusters during summer months. Like other members of the genus Galium, its stems are distinctively square in cross-section. The plant plays a modest role in wetland ecosystems, providing cover for invertebrates and contributing to the structural complexity of marginal vegetation. Its widespread distribution across three continents and tolerance for a range of wetland conditions contribute to its secure conservation status. The species has limited documented economic uses but is ecologically representative of healthy freshwater marginal habitats.
