Abstract

Gametophyte development in Arthromeris himalayensis was studied and found to be of “Drynaria type”. Germination occurred 9–10 days after sowing of spores. Some prothalli showed an initial archegonial phase, which persisted throughout gametophyte development and the antheridial phase developed on separate thalli a few days later and persisted throughout the life span of the gametophytes. This type of development of sex organs may be considered as a variant new type from the previously reported types by earlier authors. This variant type is described here as “type H”. This type of gametangial development on separate prothalli is an indication of adaptation for out breeding.
