(Selinocarpus)
Acleisanthes is a genus of flowering plants in the Bougainvillea family, Nyctaginaceae. There are currently 16 species. The generic name is derived from the Greek words (akleistos), meaning "not closed," and (anthos), meaning "flower." 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.
