Clovenlip toadflax

Clovenlip toadflax refers to a flowering plant in the genus Linaria (family Plantaginaceae, formerly Scrophulariaceae) distinguished by the characteristic two-lipped or cloven flower structure typical of the toadflax genus. Toadflaxes produce snapdragon-like flowers with an upper and lower lip structure, an orange-tipped palate closing the throat of the corolla, and a long nectar spur at the base of the corolla tube. The clovenlip epithet likely references an especially pronounced or distinctly divided lip structure in this species compared to typical toadflaxes. Linaria species inhabit a range of open, often disturbed habitats including rocky slopes, sandy soils, old walls, dry grasslands, and roadsides across Europe, the Mediterranean region, and western Asia. Several annual and perennial species are known for their rapid colonization of disturbed ground. The flowers of many Linaria species are pollinated by bumblebees strong enough to force open the closed throat, rewarding them with nectar from the spur. Some toadflax species are considered agricultural weeds in cereal crops and disturbed habitats, while others are prized as wildflowers and garden ornamentals.

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.
