| The gametes are isogamous or anisogamous and are produced from the plurilocular sporangia of gametophytes. |
| The surface wall of Tmesipteris gametophytes does not have the appearance of a suberized wall. |
| It is concluded that mosses suffer detrimental effects after exposure to Asulox at concentrations similar to those that affect fern gametophytes such as bracken. |
| To expose gametophytes to particular photoperiodic conditions, the bagged Petri plates were placed in a light-tight box over which was installed the fluorescent source. |
| After 8 to 9 weeks, archegonia had developed on the lower surface of the gametophytes just behind the growing apex. |
| Those gametophytes consisted of short, curved uniseriate filaments of 2-3 cells, some bearing antheridia. |
