polyodic

from The Century Dictionary.

• In biology, advancing along several paths: used by Giglio-Tos, in the phrase polyodic development, opposed to the monodic development advocated by him, which sets out with the principle that owing to the nature of ‘bimolecular development’ two daughter-cells must be different from each other and from the mother-cell.
• In music, same as polyphonic, 3. Attempts are occasionally made to differentiate these terms (as by Rockstro in Grove's Dict. of Music (edition 1883), III. 288, note), but they are not sustained by usage.
