Pigment composition in C. gracilis petals with different spot phenotypes

		Phenotype
		Basal spot	Central spot	Central & Basal spot	No spot
Petal section	Top	0.171 (±0.050), 5	0.132 (±0.026), 3	0.205 (±0.102), 3	0.137 (±0.033), 2
	Center	0.227 (±0.078), 2	3.524 (±1.599), 5	2.717 (±0.179), 3	0.143 (±0.026), 2
	Base	4.55 (±1.020), 5	0.494*, 1	5.316 (±1.091), 3	0.355 (±0.115), 2

Numbers refer to the ratio of cyanidin+peonidin: malvidin (mean ± standard deviations), followed by number of individuals sampled. Amount of each pigment was inferred from the average peak height between 10.4–10.5 min. for cyanidin, 11.1–11.2 min. for malvidin, and 12.3–12.4 min. for peonidin.

^*All but one central-spotted individuals had spots that extended close to the petal base (on the abaxial, but not the adaxial surface), impeding dissection of spot-free tissue. Therefore, only one individual was used.
