One question, left unanswered by Hofmeister, was how the alternation of generations of the 'higher cryptogams' or archegoniates related to the life histories of 'lower cryptogams' or thallophytes.
Bower (1890) viewed the alternation of generations of archegoniates as arising from the adaptation of an initially aquatic organism for the land.
In support of his theory, Bower disputed the hitherto generally accepted homology between the zoospores of thallophytes and the spores of archegoniates.
In an obituary of Pringsheim, Scott (1895) championed Pringsheim's opinion that the free-living sexual and asexual forms of thallophytes were homologous, and that their alternation was the phylogenetic precursor to the alternation of gametophytic and sporophytic generations in archegoniates.
In type A, the archegoniate prothalli persist throughout development but the antheridiate prothalli become archegoniate in the later stages.
In Arthromeris himalayensis, the archegoniate prothalli resemble type I, which is cordate shaped.
From the above discussions, it may be concluded the Arthromeris himalayensis gametophytic generation shows some derived developmental features: 1) dioecious prothalli promotes intergametophytic fertilization (may be of sibling and/or non-sibling mating); 2) archegoniate prothalli that are meristematic and cordate shaped, continuously producing archegonia, increase the chances of sporophyte production; and 3) long-lived gametophytes (more than 110 days) that also promote intergametophytic fertilization.
