Hairy waterclover as seen along the Deschutes River just south of Heritage Park......July 27, 2011. Note the numerous stolons by which this species spreads. Recently emerged banks here can look like they are covered with clovers (Trifolium sp.) but one must look for the 4 leaflets to identify this as Marsilea.
