| Description | Five natural hybrids with C. heterophyllum were confirmed through the study of herbaria and field investigations. They are C. acaule x C. heterophyllum, C. heterophyllum x C. oleraceum, C. heterophyllum x C. palustre, C. heterophyllum x C. rivulare. A chromosome number of 2n=34 is recorded from the Czech Republic and brief comments on morphological variability are included. The distribution maps of C. heterophyllum and of the hybrids C. heterophyllum x C. oleraceum, C. heterophyllum x C. palustre and C. heterophyllum x C. rivulare in the Czech Republic are presented, based on an examination of herbarium specimens and literary data. Cenological and ecological relationships are discussed. The climatic affinity of C. heterophyllum is discussed based upon the distribution of localities within the climatic regions of the Czech Republic. |
