Coastal Ragweed

Coastal ragweed (Ambrosia hispida) is a perennial herb in the family Asteraceae, native to the coastal dunes, sandy beaches, and cays of Cuba, the Bahamas, and the wider Caribbean region. It grows in pioneer beach and dune vegetation, often forming spreading colonies that help stabilise loose coastal sands. Like other members of the genus Ambrosia, it bears inconspicuous greenish-white flowers arranged in racemes; male flower heads produce wind-dispersed pollen that can trigger allergic rhinitis in sensitive individuals. The deeply lobed, hispid leaves are adapted to reflect intense solar radiation and tolerate salt spray. Coastal ragweed plays an ecological role in early dune succession, binding sand and enabling other plant species to establish. The genus is widespread globally, with several Ambrosia species considered noxious weeds in agricultural settings, though Ambrosia hispida is restricted to its native Caribbean coastal range. The IUCN assesses it as Least Concern, reflecting adequate population size across its Caribbean coastal distribution. Pressure from coastal development and tourism infrastructure poses a localised threat to dune communities it inhabits.

Collie Jacksonia

<em>Jacksonia velveta</em>, commonly known as Collie Jacksonia, is a plant species belonging to the genus <em>Jacksonia</em> within the family Fabaceae. This species is classified as Endangered, reflecting significant concern over its population status and the ongoing threats it faces within its native range. It has been documented in terrestrial and freshwater-associated habitat types, suggesting association with diverse environmental conditions typical of its region. <em>Jacksonia</em> species are generally shrubs or small trees native to Australia, and members of this genus are frequently found in heathland and woodland communities where they contribute to ground-cover vegetation. Specific country-level records are not detailed in current documentation for this species. Dietary behavior is not applicable to plant organisms; however, like other legumes, <em>Jacksonia velveta</em> may engage in nitrogen fixation through root-associated symbioses. Biological traits of this species remain poorly documented in the scientific literature. Conservation efforts for Endangered plant species such as <em>Jacksonia velveta</em> typically focus on habitat protection and restoration.
