Task: Explanation
Input (English): Ceropegia is a genus of plants within the family Apocynaceae, native to Africa, southern Asia, and Australia. It was named by Carl Linnaeus, who first described this genus in volume 1 of his "Species plantarum", which appeared in 1753. Linnaeus thought that the flowers looked like a fountain of wax. From this the scientific name was derived: ‘"keros"’ meaning wax and ‘"pege"’ meaning fountain (Pooley, 1998). They have many common names including lantern flower, parasol flower, parachute flower, bushman’s pipe, string of hearts, snake creeper, wine-glass vine, rosary vine, and necklace vine.
