Note: There are at least three species that seem to be almost the same: S. pruinosum, S. langloisii and S. ensigerum, and these photos could be of any of the three; however, most of the local literature mentions only S. pruinosum. The plants from Lake Georgetown have light green stems and leaves; the Winedale plant leaves are darker green.
