strong allele; floral defects in the first and third whorls; sepals fuse partially or completely along their margins, with more extended frequency in apical flowers; number of stamens in basal flowers is increased and two stamens often displays partial fusion; in more apical flowers the frequency of extra stamens and of stamen-stamen fusion is decreased; margins of cauline leaves and the cotyledons have similar abnormalities of fusion, one or both margins of one or more cauline leaves are attached inappropriately at their base to the stem of the inflorescence.
