Abstract

We have obtained the first momentary photographs of sperms just as they are discharged from the antheridium of a liverwort, Conocephalum conicum, and have succeeded in monitoring the airborne sperms of bryophytes under field conditions. Airborne sperm of liverworts seems to be an effective strategy for raising the efficiency of fertilization between male and female plants separated in a drought environment.
