Nuttall’s journal contains relatively little about aquatic and wetland vegetation compared to terrestrial. He does describe a couple of oxbow lakes in eastern Oklahoma however. The first is near the Kiamichi River, seen by him during his side trip to the Red River.[June 15, 1819] “In a lake, about a mile from the Kiamesha…grew the Pontederia cordata, Nymphoea advena, Brassenia peltata, and Myriophyllum verticillatum, all of them plants which I had not before seen in the territory, and which I have found chiefly confined to the limits of the tide water.” (pg. 181) [Pontederia cordata is pickleweed; his Nymphaea advena is Nuphar lutea, yellow pond lily, and is today one of the most commonly seen shallow water aquatics in eastern Oklahoma. His Brassenia peltata = Brasenia Schreberi, purple wen-dock [per Lottinville]; Myriophyllum verticillatum, whorl-leaf watermilfoil, is native to much of North America, but has not been reported from Oklahoma; what Nuttall saw was more likely M. heterophyllum or M. pinnatum.
