Common in Pine Barren streams, occurring- locally also in the

 Barrens, where it gTows in great masses, its long leaves and 

 stems swaying in the current and often associated ^^■ith Bleocharis

 often grows upright with much shorter and stitYer stems, pre-

* The references to S. debilis by Harshberger, Proc. Ac. Nat. Sci., 1900, 

 623-671, must surely apply to S. americanus, as I have never found vS*. debilis 

 growing as there described, nor do I know it from the coast.
