Thus, Pringsheim interpreted the multicellular fruit of Coleochaete as a reduced asexual generation that was fundamentally similar to a free-living asexual thallus.
This change would accentuate the alternative routes that were proposed for the origin of the asexual generation of land plants (Bower, 1935; p.
The bombshell dropped when Strasburger (1894) reported that the asexual generation of ferns had twice the number of chromosomes of the sexual generation.
Therefore, asexual generation A could not correspond cytologically to the asexual generation (sporophyte) of land plants.
Thus, Dictyota provided an example of a regular alternation between a haploid sexual and diploid asexual generation that were "in all morphological respects .
