In the riverbed grows C. affinis fully exposed to the sun. They form dark flecks near the rapid in the shallow, cloudy water. The very small specimens grow in dense mats together with some Hydrilla and Vallisneria. coll. B 805 |
In more sheltered places C. affinis develops rather
big leaves. coll. B 805 |
Plants from the bank grow merely in clay. The plants are very deep
rooted, the white part of the petioles were below surface. coll. B 805 |
