title: Handedness in duckweed: double flowering fronds produce right- and left-handed lineages.
abstract: Frond lineages of Lemna perpusilla Torr. (strain 6746) show handedness with respect to frond emergence sequence and flowering that is related to the pocket of origin on a double flowering mother frond. Flower position is a fundamental manifestation of frond asymmetry.
