The name Aerangis is the combination of two Greek words: aer ("air") and angos ("vessel"), the latter probably referring to the spur beneath the lip which contains nectar. There are many flowers on each raceme. The flowers are often very delicate with a lacy appearance and are most white or cream in color. They are predominantly fragrant in the evenings, attracting moth pollinators to the nectar.
Number of species: About 50
