The development of the flowers and fruits of loblolly bay (Gordonia lasianthus) is described in detail. Tests of meteorological conditions affecting the opening and closing of mature capsules reveals that seeds are typically released only when relative humidity falls below a critical threshold of 67%. Seedfall tests indicate that differences in the expressed aerodynamic pattern may account for variation in observed seedfall densities and affect horizontal displacement.
