• flower is sessile
• stamens and ovary are ± white
• other parts are highly variable in color

If the stamen and ovary colors differ, some on iNaturalist claim that the ovary color determines the species, but Jerpson says the anther color determines, and FNA simply says that a range of intergrade hybrids exist. The direction of anther dehiscence may be the correct identifier, but I can’t tell the difference in photos.
