Phlox glaberrima interior MARSH PHLOX

Busy has been the word for the last week. I have been concentrating most of my efforts on finishing a complete review of the wildflower species' list from the James Woodworth Prairie Preserve. As you can see, I've made it to the P's. This species is Phlox glaberrima interior MARSH PHLOX. As the common name (from the USDA common name list) implies, this plant grows in wetter areas. The flowers are pink to purple.

This species has a Latin trinomial. Botanist try to keep names to genus: Phlox (flame, blaze) and descriptive adjective: glaberrima (most smooth, most without hair). But this species is close enough to other phlox species that it needed a third descriptor: interior (inner).
