In many groups of eudicots with an imbricate (quincuncial) calyx, inner and outer sepals are of somewhat difference size and/or shape, which also results in a minor floral asymmetry.

The immense diversity of floral monosymmetry and asymmetry across angiosperms

For example, a "beardtongue" staminode like the one in Penstemon (Cheloneae, Scrophulariaceae) also occurs in Jacaranda (Bignoniaceae); petal aestivation, or folding in the buds, shows both ascending and descending patterns within Scrophulariaceae, Lentibulariaceae, and Bignoniaceae, ascending and quincuncial patterns within Acanthaceae, and descending and quincuncial patterns in Orobanchaceae [whereas their presumed closest relatives, Rhinantheae (Scrophulariaceae) have ascending petal folding]; personate corollas similar to those of Antirrhineae (Scrophulariaceae) are exhibited by some Acanthaceae, Gesneriaceae, Bignoniaceae, and Lentibulariaceae; other parallelisms occur in ovary structure, ovule number, sensitive stigma lobes, and postgenital fusion of the anthers (Endress, 1994).
