bo tree

(Bot.) The peepul tree; esp., the very ancient tree standing at Anurajahpoora in Ceylon, grown from a slip of the tree under which Gautama is said to have received the heavenly light and so to have become Buddha. [ 1913 Webster ]

The sacred bo tree of the Buddhists (Ficus religiosa), which is planted close to every temple, and attracts almost as much veneration as the status of the god himself. . . . It differs from the banyan (Ficus Indica) by sending down no roots from its branches. Tennent. [ 1913 Webster ]
