Brunfelsia plowmaniana[1] is a species of flowering plant of the nightshade family that is native to the cloud forests of the Bolivian and Argentinian Andes.

The species was named in honor of the American botanist Timothy Plowman (1944-1989) who had worked on neotropical plants of ethnobotanic importance and provided the first and only comprehensive taxonomic treatments of the genus Brunfelsia.

They vary in size and shape, but are usually widest above the middle with a rather abruptly narrowed apex, similar to many Myrtaceae.

The raised and somewhat cartilaginous ring of the corolla throat is reminiscent of that of species of Prestonia (Apocynaceae) from the same geographic region; it probably reflects adaptation to pollinator foraging behaviour.

Brunfelsia plowmaniana lives exclusively in Andean humid or cloud forests and shares its habitat with tree ferns like Dicksonia sellowiana as well as with members of the Podocarpaceae, Betulaceae, Cunoniaceae, Myrtaceae, Clethraceae and Caprifoliaceae families and numerous other Solanaceae.

About one in three specimens of Brunfelsia plowmaniana is closely associated with epiphytic lichens, mosses and liverworts, reflecting the cloud forest habitat.
