Notes

Flowers  August to October

Wetland Indicator: NA

It is thought that this species may have originated by hybridization of S. cordifolium and S. laeve. The first two photos were taken in a rush and were only later identified to be of S. lowrieanum. The last two pictures were taken many years ago and may be of S. urophyllum.
