Description
Species Description - Found occasionally throughout most of the range of S. ecirrhata, may reflect hybridization with S. herbacea var. lasioneura. It is erect like S. ecirrhata, with the peduncles mainly below the foliage-lvs, but it averages taller, with more numerous lvs (many of them tendriliferous), and has more numerous (mostly more than 25) fls on longer peduncles.
