Funny, I always thought Schuyler in "Closed Gentian Distances" was looking at gentians (flowers). In John's reading of this poem the speaker of the poem is taking gentian (the root of this plant, ground up) as a digestive aid. I'm not saying the skeptic is wrong; I never knew that gentian was a digestive aid in the first place. But since Schuyler is always writing about flowers anyway, it would have never occured to me to look further into this plant.
