Family: Gentianaceae
Anthocleista grandiflora (forest fevertree, forest bigleaf) is a large evergreen tree native to tropical and southern Africa, where it grows along forest margins, riverbanks, and moist woodlands. It can reach heights of up to 40 meters, with a straight trunk and a broad, spreading crown. The species is easily recognized by its enormous glossy leaves, which can reach over 1 meter in length, and its clusters of showy, white, tubular flowers that attract a variety of pollinators. The tree is sometimes planted as an ornamental for its dramatic foliage and striking appearance.
Although it has not naturalized or become invasive outside its native range, it grows well in moist, tropical environments and produces abundant wind-dispersed seeds capable of germinating in shaded forest conditions. If introduced and left unmanaged, it could establish in riparian or forested habitats, where its rapid growth and dense canopy might outcompete native vegetation. While not yet naturalized in Hawaiʻi, its biology and environmental preferences suggest that it should be approached with caution before planting.
