'Marchantiales' is an order of thallose liverworts that includes species like ''Lunularia cruciata'', a common and often troubleseome weed in moist, temperate gardens and greenhouses.
As in other bryophytes, the gametophyte generation is dominant, with the sporophyte existing as a short-lived part of the life cycle, dependent upon the gametophyte.
The genus ''Marchantia'' is often used to typify the order, although there are also many species of ''Asterella'' and species of the genus ''Riccia'' are more numerous.
The majority of genera are characterized by the presence of (a) special stalked vertical branches called archegoniophores or carocephala, and (b) sterile cells celled elaters inside the sporangium.
