- Climbing asystasia — A climbing plant species in the genus Asystasia, family Acanthaceae, native particularly to the forested areas and tropical regions of West Africa. It is distinguished by its long, flexible shoots that lean on surrounding vegetation to reach the light, having glossy leaves and compact terminal inflorescences with tubular flowers, often white or cream, adapted for pollination by large insects in the forest canopy.
- Atoll — A ring-shaped or horseshoe-shaped coral island, reef, or chain of islands surrounding a lagoon, specific to warm tropical seas. Atolls are formed over thousands of years by the accumulation of coral skeletons on the rims of extinct volcanic cones that slowly subsided into the sea.
- Attalea — A genus of tropical palms native to the warm regions of Central and South America, belonging to the family Arecaceae, known for their impressive size and robust trunks. These plants exhibit a remarkable adaptive structure, featuring gigantic pinnate leaves and nut-like fruits from which high-quality industrial vegetable oils or strong fibers used in manufacturing are extracted.
- Aubletia — An historical scientific name or taxonomic synonym attributed to a genus of exotic plants, named in honor of the French botanist and explorer Jean Baptiste Christophore Fusée Aublet.
