"Acleisanthes" is a genus of desert plants in the family Nyctaginaceae. There are currently 16 species. In the year 2000 studies by Rachel A. Levin reclassified the members of two genera, "Ammocodon" and "Selinocarpus" into genus "Acleisanthes". Plants of this genus are known commonly as trumpets, due to the elongated, open-ended shape of their flowers. These are arid-adapted perennials with thick taproots which are usually compact and low to the ground or slightly ascending. An individual plant may have cleistogamous (unopening and self-pollinating) flowers as well as opening flowers which are usually nocturnal as a water-saving adaptation and are pollinated by night-flying or crepuscular insects such as hawkmoths. Flowers are usually white, sometimes yellow. These plants are native to the Chihuahuan and Sonoran Deserts of Mexico and the United States.
