There are two varieties associated with this species and var speciosa has upper bracts obtuse rather than narrow and/or acuminate (long-pointed). The sepals are strongly ciliolate whereas the other variety has fewer cilia on the sepals. The two varieties are geographically separated and variety speciosa occurs in western Kentucky.
