The bud seemed to follow the moon, and when the plants were placed at a window with a western aspect a fresh movement was seen, and this continued until the moon disappeared behind the hills. Edited by Frank Crisp, Journal of the Royal Microscopical Society, Ser. II--Vol. III, 1883
... heliotropism, selenotropism and phototropism. These three are concerned with light; the light of the sun, the light of the moon, and light in general as opposed to darkness. Theodore Savory, Instinctive Living: A Study of Invertebrate Behaviour, 1959
