common poisonrope

<em>Strophanthus speciosus</em>, the common poisonrope, is a woody climbing vine in the family Apocynaceae, native to Africa. It is characterised by striking flowers with long, strap-like petal extensions or "tails" that dangle from the corolla, attracting specialist pollinators. Like other members of the genus Strophanthus, it produces toxic cardiac glycosides, particularly strophanthin, in its seeds, which have been used historically in the preparation of arrow poisons across various African cultures and have also been investigated for medicinal applications in cardiology. The species typically grows in forest margins, woodland edges, riverine scrub, and disturbed vegetation across its African range, where it uses supporting vegetation to climb towards the forest canopy. <em>Strophanthus speciosus</em> is assessed as Least Concern on the IUCN Red List, reflecting an adequate distribution across suitable African habitats. Detailed country-level distribution data are not fully compiled. Biological traits such as average vine lifespan, stem dimensions, body mass, and comprehensive dietary or physiological data remain poorly documented in the scientific literature. The species is of historical and ongoing pharmacological interest due to its cardenolide chemistry.
