Descriptions of the anatomical structures of liverworts. Furthermore, in the late 1800s, a German botanist, Leopold Kny, made exceptional illustrations of Marchantia that most printers preferred to use. Here is Kny's wall chart of the male gametophyte of Marchantia. KNY'S WALL CHART SHOWING MALE GAMETOPHYTE OF Marchantia...

Like Marchantia, Ceratopteris is homosporous and produces only one type of haploid spore. Although the sex of the Marchantia gametophyte is determined genetically by sex chromosomes, the sex of the Ceratopteris gametophyte (male or hermaphroditic) is determined epigenetically by the pheromone antheridiogen.

Note that in the last of the three examples just illustrated, the complex umbrella-like structure is part of the Marchantia gametophyte.

In Marchantia all of this sex happens almost "in the air." Rather than being produced in pouch on the gametophyte surface, the gametangia are attached to a...
