The reasons for Drummond's phlox and the pointed phlox each producing flowers of a particular color when they are sympatric in some areas of Texas could be:

1. Hybrids of the two species have very low fertility: This could be a reason as it suggests that cross-breeding between the two species is not beneficial for their survival and reproduction. Therefore, maintaining distinct flower colors could help ensure that each species primarily attracts its own pollinators, reducing the likelihood of producing less fertile hybrid offspring.

2. Hybrids of the two species produce flowers with an intermediate color that are not recognized by any pollinators: This could also be a reason. If the hybrid flowers' color is not attractive to pollinators, it would reduce the chances of these hybrids surviving and reproducing. Therefore, each species maintaining its own distinct flower color could be a strategy to attract the right pollinators and ensure their survival.

3. Drummond's phlox plants that produce blue flowers absorb sunlight more efficiently and overheat in these areas: This could be a reason if it's true that blue flowers cause Drummond's phlox plants to overheat. The red color of Drummond's phlox flowers could be an adaptation to prevent overheating, while the pale blue color of pointed phlox flowers might be suitable for their own survival in the same environment.

So, all the options could be reasons for Drummond's phlox and the pointed phlox each producing flowers of a particular color when they are sympatric in some areas of Texas.
