Summary
The development of the gametophyte inPteris biaurita is of thePteris longifolia type.
There is no typical cushion which is met with commonly in ferns behind the notch in well-developed prothalli.
Antheridia with motile sperms apparently capable of fertilization are formed but archegonia are eliminated out of the life-cycle of the gametophyte.
The dehiscence of the antheridia occurs by the bodily lifting of the opercular cell which is thrown off with some force.
The embryo formation is by apogamous bud.
