Climbing cactus

Climbing Cactus 2 represents another species in the cactus family Cactaceae that adopts a scandent, climbing, or epiphytic growth form rather than the typically upright, succulent form associated with desert cacti. The evolution of climbing habits in cacti occurred multiple times across the family, primarily in tropical forest environments of the Americas where vertical forest structure provides opportunities for sun-seeking growth strategies. Epiphytic and climbing cacti include species in genera such as Rhipsalis, Lepismium, Disocactus, and Weberocereus, many of which produce pendant or scrambling stems adapted to clinging to bark and mossy tree surfaces in cloud forests and tropical lowland forests. These species often have flattened or cylindrical stems with reduced or absent spines, modified for life in humid, shaded forest environments. Flowers are typically small and numerous in the epiphytic genera, though some climbing ground-level cacti produce large, showy, nocturnal blooms. Several species are used in traditional medicine in their native range. The conservation status of individual climbing cactus species varies greatly; those restricted to threatened cloud forest or dry tropical forest habitats are of conservation concern, while others are widespread and adaptable.

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.
