"Indian fig tree," 1630s, so called in reference to a tree on the Iranian coast of the Persian Gulf under which the Hindu merchants known as banians had built a pagoda. From Sanskrit vanija "merchant." The banians also were noted as rigorous abstainers from flesh-eating and for their reverence for all animal life, hence banian-hospital for "animal hospital" (1813).
