Textbook and readings
There is no official text book. Instead, you will be assigned readings from the primary literature to go with the lectures.

- Watch This: movie of bryophyte gametes
"Whitish smoke in the movie are small droplets containing smreps (deliberate misspelling of word for male gametes).
The smreps in the droplets are still un-motile. When touch the
water, they begin to swim. In our experiments, misting with water is
trigger of the explosion. If antheridia were mature, the explosion
begin within few minutes. The event continued about for 10 min.
Intense light for video recording also seems to accelerate the
phenomenon. Each antheridia is deeply sunk in a cavity of
antheridiophore and there is a very small pore on the top of each
cavity. Swollen cells of surrounding tissue might cause the pressure
force. Cavers (1903) and Muggoch & Walton (1942) also discussed about the mechanism, but, I think no one examined about the detail mechanism of the phenomenon.
In Hiroshima, the season of mreps dispersal is Spring (April to May).
In our field observation, we detected many airborne smreps in the
sunny day after rain shower.
I do not have detail data about how many species of liverworts have
airborne mreps. At least, Asian species of Conocephalum (C.
japonicum) do in the same manner." M. Shimamura
