Other info. - This hairy species can be found in the Ozark Region of Missouri. It typically grows in acid soils. The plant is pubescent throughout and some authors try to separate the species into several varieties based on this pubescence. I won't go into those here. Another species, S. pauciflora Muhl., is very similar and the two may not be different taxonomically.
Arrow shows one of the tubercles (two can be seen in this pic).
