Quantification of I. amara petal surface area and petal cell size

	Petal area, mm2		Petal cell size, μm2
	St. A1	St. A2	St. A1	St. A2
aD petals	3.6 ± 0.8	10.2 ± 2.1	241.92 ± 60.04	490.91 ± 94.94
aB petals	5.7 ± 1.5	38.1 ± 8.0	239.66 ± 49.57	534.40 ± 87.94
aB/aD	1.6 ± 0.2	3.7 ± 0.4	0.99 ± 0.32	1.09 ± 0.27

Values with standard deviation are given for average adaxial (aD) and abaxial (aB) petal surface area (mm²) and cell size (μm²) from flowers at stages (St.) A1 and A2. Differences between adaxial and abaxial petal values are given as ratios (aB/aD).
