Table S2.

Non-temperature adjusted means and standard errors associated with pollen performance traits in all four focal taxa following cross- and self-pollinations. Styles in which no pollen tubes were observed at the stigma-style junction were not used to generate these values.

			Pollen Tube Growth Rate (PTGR, mm hour−1)			Proportion of the style length (traveled per hour)
