The young sporophytes arise apogamously from the tips of the branches of
prothalli. Gametophytic tissue was also induced to produce a single leaf. Such

Contrary to it, in apogamously produced diploid sporophytes of Asplenium
trichomanes (Bouharmont, 1972a) and A. septentrionale (Bouharmont, 1972b) all
chromosomes showed pairing indicating that tetraploids were of autoploid-origin.
Sporophytes were produced apogamously in two species from gametophytes
cultured under light conditions; in four species from cell colonies produced in the
dark without the formation of gametophytes; and in six species from spore-origin
...
