Christmas candlestick

The Christmas candlestick (Cassia alata), more commonly known as candle bush or ringworm bush, is a shrub or small tree in the family Fabaceae, native to the New World tropics, primarily Central America, Mexico, and northern South America. The species is widely naturalized throughout the tropics and subtropics globally, having spread through cultivation and accidental introduction. It produces distinctive upright, spike-like racemes of bright yellow flowers that resemble a lit candelabrum, giving rise to its common names. These inflorescences are borne at the tips of branches and can reach up to thirty centimeters in length. The large pinnate leaves are characteristic of the genus Cassia. Cassia alata has been used extensively in traditional medicine across its native and introduced range, particularly for treating fungal skin conditions such as ringworm, a use supported by documented antifungal activity of compounds in the leaves. The species grows rapidly in disturbed habitats, roadsides, and forest margins, and is considered weedy in many regions. It is a host plant for the larvae of several sulfur butterfly species. While not a significant conservation concern, its invasive tendencies in non-native regions warrant management attention.

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.
