Brugmansia arborea (angel's trumpet) is a species of flowering plant in the family Solanaceae. The IUCN has classed Brugmansia arborea as Extinct in the Wild.
Brugmansia arborea is an evergreen shrub or small tree reaching up to 7 metres (23 ft) in height. The ovate leaves have coarsely toothed margins when in their best condition. The leaves, flower stalks, fruit, and especially the young shoots are covered with fine velvety white down. Flowers are strongly fragrant, trumpet-shaped, nodding to sub-horizontal, white to ivory-white or cream. At 12–17 centimetres (4.7–6.7 in) long, the flowers are the shortest of all Brugmansia. Flowers are produced almost continuously in smaller quantities, unlike many other Brugmansia that flower in larger flushes. The ovoid fruit have an average length of 6 centimetres (2.4 in) and width of 4.5 centimetres (1.8 in). The calyx is slit along one side and is very long in relation to the flower, and in this respect is often used as a quick check to verify correct identification. With a few exceptions, the green calyx usually reaches down almost all the way to the flower corolla's mouth.
In his 1753 Species Plantarum, Carl Linnaeus published Datura arborea using as his type specimen a drawing by Louis Feuillée from 1714 with name Stramonioides arboreum, oblongo et integro folio, fructu laevi, vulgo Flori pondio. Then Robert Sweet, in his 1818 Hortus Suburbanus Londinensis, published the modern version of the name to be in the separate genus of Brugmansia. Since then, many authors have published many different plants with one of those names, causing much confusion in the taxonomy of these plants. "Datura arborea" has many times been incorrectly used for almost any white-flowered Brugmansia plant, even in scientific literature.
