strong allele; semidominant; variable floral defects in all 4 whorls; fusions between organs in a whorl or in adjacent whorls; fused stamens, stamen mosaic organs, and reduced stamen-like organs, which severity increases acropetally; slight increase in sepal number and decrease in petal number, narrow sepals and petals, sepals also varies widely in size and shape; surface of gynoecia appears normal, but there is some reduction in fertility; disrupted phyllotaxy of flowers and initiate more flowers at a time than wild type.
