Discussion | The name spider rose-gentian is derived from the appearance of the involucre subtending each solitary flower or cluster of a few flowers, which comprises two to four or more closely spaced pairs of narrowly linear leaves.

There are historical records of Sabatia dodecandra from Connecticut and New York. Reports from west of the range given here have been based on a concept of the species that included S. foliosa. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
