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.

Common Funnel

<em>Infundibulicybe gibba</em>, commonly known as the common funnel, is a saprotrophic fungus in the family Tricholomataceae. It has been documented in Denmark, Norway, Sweden, and the United States, and is known to occur more broadly across temperate regions of the Northern Hemisphere. The species typically inhabits forest floors and areas with decomposing wood and leaf litter, where it plays a key role in breaking down organic matter and recycling nutrients. <em>Infundibulicybe gibba</em> produces characteristic funnel-shaped fruiting bodies, typically pale buff to pinkish-tan in color, with deeply decurrent gills running down the stipe. It is assessed as Least Concern, reflecting its wide distribution and occurrence across a variety of woodland habitats. The common funnel is a common and recognizable species in temperate forests throughout its range. Biological traits of this species remain poorly documented in the scientific literature. As a saprotroph, it contributes to decomposition processes in forest ecosystems and is often found growing in arcs or rings in leaf litter and grassy clearings within woodland areas.
