climbing-oleander

Climbing Oleander, Strophanthus gratus, is a woody liana or climbing shrub in the family Apocynaceae native to tropical West and Central Africa, occurring in rainforest margins, gallery forest, and secondary forest from Senegal to Uganda. The species belongs to a genus celebrated for the cardiac glycosides and arrow poisons produced in the seeds; Strophanthus species were the source of the drug ouabain (g-strophanthin), historically used in cardiac medicine and by African hunters as an arrow poison applied to hunting darts. Climbing Oleander produces large, funnel-shaped flowers with white to pale pink twisted petals and a fringe of elongated lobes at the corolla mouth, borne in terminal cymes that are highly ornamental. The name 'climbing oleander' refers to the superficial resemblance of the flowers to the related Mediterranean oleander (Nerium oleander). The species climbs by twining its stems around supporting vegetation and is occasionally cultivated as an ornamental in tropical gardens. The seeds contain strophanthin and other potent glycosides that affect the cardiac system; all parts of the plant are toxic if ingested. The species is not currently assessed as threatened within its native tropical African range.

common greasewort

<em>Aneura pinguis</em>, commonly known as common greasewort, is a liverwort belonging to the genus Aneura within the family Aneuraceae. This cryptogamic plant inhabits ecosystems across Asia, Europe, and North America, thriving in moist or waterlogged environments. Its range encompasses Taiwan in Asia, six European countries, the United States in North America, and Brazil and Colombia in South America, indicating a broad geographic distribution across multiple continents. Common greasewort is assessed as Least Concern on the IUCN Red List. The species typically forms flat, ribbon-like thalli in damp habitats such as stream banks, wet rocks, and boggy ground. Biological traits of this species remain poorly documented in the scientific literature.
