Marchantiales
Marchantiales is an order of thallose liverworts (also known as "complex thalloid liverworts") that includes species like '' Marchantia polymorpha'', a widespread plant often found beside rivers, and ''Lunularia cruciata'', a common and often troublesome 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 carpocephala, and (b) sterile cells celled elaters inside the sporangium. Phylogeny (extant Marchantiales) Based on the work by Villarreal et al. 2015 Phylogeny (extant and extinct Marchantiales) Extinct complex thal ...

Cryptomitrium
''Cryptomitrium'' is a genus of complex thalloid liverworts in the family Aytoniaceae. The genus name means “hidden turban” in reference to the inconspicuous sheath around the immature sporangium. Description Sporophyte bearing receptacles are unlobed on elongate, somewhat grooved stalks, which appear pale throughout or brownish purple near the base. The receptacle is a convex-expanded disc, thinning towards the margins. Mature sporangia are brown, nearly spherical with very short seta, three to seven per receptacle, each opening by a lid-like operculum. The sporangia mature in early spring.

Mannia
''Mannia'' is a genus of liverwort The Marchantiophyta () are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of ...s belonging to the family Aytoniaceae. It has a cosmopolitan distribution. Species The following species are recognised in the genus ''Mannia'': * '' Mannia androgyna'' (L.) A. Evans * '' Mannia californica'' (Gottsche) L.C.

Reboulia Hemisphaerica
''Reboulia hemisphaerica'', the hemisphaeric liverwort or small mushroom-headed liverwort, is the only species of liverwort in the genus ''Reboulia''. A possible second species ''Reboulia queenslandica'' (Stephani) M. Hicks was published in 1992, but it was later determined to be a polyploid cross between two varieties of ''R. hemisphaerica'', so not a distinct species. Subsequent lists and publications do not recognize it as distinct. Riccardin C Riccardin C is a macrocyclic bis(bibenzyl). It is a secondary metabolite isolated from the Siberian cowslip subspecies ''Primula veris subsp. macrocalyx'', in ''Reboulia hemisphaerica'' and in the Chinese liverwort ''Plagiochasma intermedium''. ... is a phenolic cyclic bibenzyl secondary metabolite isolated from ''R. hemisphaerica'', as is marchantinquinone.
