“ PEEPUL, s. Hind. pīpal, Skt. pippala, Ficus religiosa, L.; one of the great fig-trees of India, which often occupies a prominent place in a village, or near a temple. The Pīpal has a strong resemblance, in wood and foliage, to some common species of poplar, especially the aspen, and its leaves with their long footstalks quaver like those of that tree. This trembling is popularly attributed to spirits agitating each leaf. And hence probably the name of 'Devil's tree' given to it, according to Rheede (Hort. Mal. i. 48) , by Christians in Malabar. ”
