Which genus is in Solanaceae, Anthotroche or Angelonia?
Angelonia Angelonia is a genus of about 30 species which occur from Mexico to Argentina and is classified in the Plantaginaceae. They are herbaceous plantas occurring mainly in arid and semi-arid habitats. Most "Angelonia" species can be found in Northeastern Brazil in the Seasonally Dry Tropical Forest namely Caatinga. The flowers of "Angelonia" are highly specialized in regarding to the pollination, because they have hairs in the inner corolla, which produces oils collected by the oil bee pollinators, specially of the genus "Centris".
Acleisanthes 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 ακλειοτος ("akleistos"), meaning "not closed," and ανθος ("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. 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.
