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 Solomon'S Seal

<em>Polygonatum multiflorum</em>, commonly known as Common Solomon's Seal, is a rhizomatous perennial herb in the family Asparagaceae, order Asparagales. It is classified as Least Concern on the IUCN Red List, with stable populations across its native range. This graceful woodland plant is typically found in shaded, moist deciduous forests, woodland margins, and hedgerows, preferring humus-rich, well-drained to moderately moist soils. Its geographic range extends across temperate Europe, including Belgium, Denmark, Finland, and Ireland, as well as parts of Canada and the United States. The arching stems bear alternating, broadly elliptic leaves and hang pendulous, tubular white flowers with green tips in late spring. These flowers are followed by blue-black berries that are mildly toxic and should not be consumed by humans or pets. The genus name <em>Polygonatum</em> refers to the many-jointed rhizome, which bears circular scars from previous years' stems — historically said to resemble the "seal of Solomon." As a shade-tolerant woodland plant, it obtains energy through photosynthesis and plays a role in forest floor ecosystems by providing food and habitat for invertebrates. The plant has a long history of use in traditional European herbal medicine. Average lifespan and specific dimensional data are typical of perennial rhizomatous herbs and are not comprehensively standardized.
