| 説明 | The lower stem nodes often show adventitious roots or root buds as well as the characteristic sheathing stipule of the Polygonaceae. This obligate wetland species is an aquatic in that the leaves are often floating on the surface of still or slow moving water. The leaves are all born from along the stems rather than basally. This site lies along Spring Creek north of Burke Park near Sculpture Park, Bozeman, Montana. |
