Abstract

In this short communication, we report the observation of a tricotyledenous giant ragweed (Ambrosia trifida L.) individual. In contrast to the normal dicotyledenous pattern of phyllotaxy, this individual was observed to express three axillary meristems at each node that intersected the main stem at angles of 120°.
