The bryophyte sporophyte is not normally indeterminate, but a capacity for bifurcation in the seta has been known for some time from rare teratological specimens of both liverworts and mosses (figure 3 t). WebBryophytes are the closest extant relatives of early terrestrial plants. The first bryophytes (liverworts) most likely appeared in the Ordovician period, about 450 million years ago.

WebAccording to the Up-grade view, the first evolved Bryophyte was of the hypothetical Sphaero-Riccia type which combined the very simple thalloid gametophyte of Sphaerocarpos with the simple bag-like sporophyte of Riccia. Cavers (1910-11) developed this view and the phylogenetic tree proposed by him is shown in Figure 497. WebBryophytes originated from green Algae. Their ancestors are related to Ulotrichales (Ulothrix-like). Such ancestors formed compact masses of cells by the union of filaments. It adopted them in the terrestrial mode of life.
