Cinnamon

Cinnamon (Cinnamomum verum), also known as true cinnamon or Ceylon cinnamon, is a small evergreen tree in the family Lauraceae, native to Sri Lanka (formerly Ceylon), and also found in southern India, Myanmar, and Bangladesh. It is cultivated pantropically for its inner bark, which is dried and rolled into the familiar quills used as one of the world's most popular spices. The tree grows 10–15 meters tall in the wild but is typically coppiced to produce multiple stems in cultivation. The bark of young branches is peeled, dried, and curled to form cinnamon sticks. True cinnamon is prized for its delicate, complex flavor compared to the cheaper cassia (Cinnamomum cassia), with which it is often confused in international trade. The species has been used for over three thousand years in culinary, medicinal, and ritual contexts across Asia, the Middle East, and Europe. It is not formally assessed by the IUCN. In Sri Lanka, cinnamon cultivation is a significant agricultural industry concentrated in the wet zone southwest of the island. The essential oil contains eugenol, cinnamaldehyde, and other compounds with documented antimicrobial and anti-inflammatory properties that have attracted pharmaceutical research interest. Wild populations persist in Sri Lankan lowland forest remnants, though the species is primarily known today as a crop plant.

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.
