Plants were grown under continuous SD conditions until maturity and were dissected. Terminal and axillary flowers in 10 plants were analyzed. This corresponded to 10 terminal flowers and 46 type 3 flowers (from axillary inflorescences), 12 type 2p flowers, and 12 type 2np flowers. Sepals include regular and modified sepals. True petals are fully expanded and anthocyanin-pigmented petals. Staminate petals showed various degrees of transformation into stamens. Asymmetrical petals were found mostly in lateral position in the flowers. Data are ±se.
