Cluster-head Protea

Protea welwitschii, commonly known as cluster-head protea, is a flowering shrub or small tree in the family Proteaceae, a family renowned for producing some of Africa's most spectacular blooms. Found across savanna woodlands and grasslands in central and eastern Africa, this protea inhabits well-drained, often sandy or rocky soils in open miombo woodland systems and adjacent grasslands. The species produces globose to cylindrical flower heads with characteristic bracts, typical of the genus, which attract sunbirds and other nectarivores. Protea welwitschii is adapted to fire-prone ecosystems, where periodic burning stimulates regeneration and maintains the open habitats the species requires. The Proteaceae family, concentrated in the Cape Floristic Region and Australia, represents an ancient lineage dating to the Gondwana supercontinent. Unlike the more famous Cape proteas, P. welwitschii occupies tropical African biomes extending from Angola and Zambia through Tanzania and Kenya. It is assessed as Least Concern by the IUCN. The plant plays an ecological role as a nectar source in African savanna systems where flowering plants that bloom in the dry season provide critical resources for pollinators and nectarivores during periods of food scarcity.

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.
