Comments: This species is mostly seen as a shrub or treelet in early successional areas, but it can grow into a medium-sized tree with a dbh of 30 cm. The other Cestrum species in the region are glabrous. Because they usually do not have paired leaves, Cestrums are not immediately identifiable as Solanaceae. Some have a strong rank solanaceous odor, but others have none. All species have tubular nocturnal flowers, mostly pollinated by Lepidoptera. Many species of Solanaceae in the genera Cestrum and Solanum are called "Zorillo" because of their disagreeable odor. Those with red or orange fruits are often called "Tomatillo" (= little tomato).
