  1. (a) Summary of genotypes vs. ploidy levels found for each species: Triploid (3x) and tetraploid (4x) genotypes found either in vegetative parts of the blade or gametes, (Mx) mixoploid genotypes found in vegetative parts of the blade, (Mp) multiploid gametes with the same or higher ploidy than the vegetative part of the blade, and (Zp) Zygotospores that could be found alone or with vegetative parts of the blade in mixoploids or regular blades and other cells of different ploidies. (b) In detail, all the genotypes found in this study divided in 19 groups according to the exact ploidy levels found. For P. linearis, Group 1: Triploids (3x), Group 2: tetraploids (4x), Group 3: Mixoploids 2x/3x or 2x/4x, Group 4: Mixoploids 3x/4x, Group 5: Zygotospores 6x, Group 6: Zygotospores 6x found in mixoploids (2x/3x), Group 7: Zygotospores 8x found in mixoploids (2x/4x or 3x/4x). For P. umbilicalis, Group 8: tetraploids (4x), Group 9: triploids (3x), Group 10: genotypes of several types (multiploid gametes 3x, blades 4x with gametes 2x and 4x, mixoploids 2x/3x with zygotospores 6x, zygotospores 6x and female gametes 2x, and zygotospores 8x). For P. dioica, Group 11: tetraploids 4x, Group 12: triploids 3x, Group 13: multiploid gametes 4x; Group 14: multiploid gametes 3x, Group 15: multiploid gametes 3x and 4x, Group 16: zygotospores 8x, Group 17: tetraploids 4x with zygotospores 8x, Group 18: gametes 2x and zygotospores 8x, Group 19: gametes 3x and zygotospores 8x. In each case the number of individuals is given in brackets. In (a) and (b), zygotospores are 2n, blades and gametes are n. Mixoploid blades contain more than one ploidy level, separated by a “/” (e.g., 2x/3x). Gametes with the same and lower ploidies found in the same blade, indicated separated by a “,” (e.g., 2x, 3x). Gametes with the same and higher ploidy levels (e.g. 3x, 6x, 12x) found in the same blade are labelled by “Mp”. Zygotospores (Zp) (the result of fecundation) and blades are sometimes found mixed with gametes (unfertilized); in these cases ploidy levels of each cell are indicated separated by a “+” (e.g. 4x + 8x). Numbers in brackets represent number of genotypes for each group.
