He is largely known for investigations of cryptogams (algae, hepatics, mosses) found in the department of Manche.

Although it is unique among hepatics as a submerged aquatic, it is not the only aquatic liverwort.

On opening a few of these inrolled apices, it is noticed egg-cases similar to those found in leaf domatia; epiphyllous hepatics were also found.

The basalt walls are home to a wide variety of ferns, mosses, hepatics and lichens, many of which grow only in the Columbia River Gorge.

The northern polar desert has few macroscopic plants or none; where present the vegetation forms a single thin layer, with cryptogams (algae, lichens, mosses and hepatics) dominant.

Rodway also compiled a complete description of the mosses and hepatics of Tasmania, and contributed numerous papers to the Papers and Proceedings of the Royal Society of Tasmania.

This probably stemmed from the superficial appearance of some thalloid liverworts (which resemble a liver in outline), and led to the common name of the group as hepatics, from the Latin word hēpaticus for "belonging to the liver".

The maritime antarctic as a whole has 20% more lichens than the continent and 150% more mosses; in addition it has 25 taxa of hepatics to the continent's one, and two species of angiosperms that have not yet been found on the continent.

Air-dispersal probably accounts for the distributions of some liverworts, though many spores are not long-lived in a desiccating atmosphere, but the presence of certain hepatics on Ascension Island, St Helena and Tristan da Cunha seems to confirm it.

The Tortula-Grimmia association of mosses occurs on wet alkaline substrates (for example marble outcrops); species of the named genera form deep carpets in which other mosses, lichens and hepatics settle, forming some of Antarctica's most complex stands of vegetation (Gimingham and Smith, 1970).

It is estimated that there are about 9000 species of liverworts.

Most other liverworts are thalloid, with no evidence of leaves.

Blasiales is an order of liverworts with a single living family and two species.

Study of the spore wall indicates a relationship with the liverworts.

There is a rich variety of mosses and liverworts present.

There are also a number of endemic lichens and liverworts.

Treubiaceae is a family of liverworts in the order Treubiales.

The area is also good for mosses and liverworts.

Then other plants, including moss and hornworts, evolved from liverworts.

The liverworts are a group of simple plants.

Sphaerocarpales is an order of plants within the liverworts.

He also studied and described the genus Marchantia of liverworts.

They also include the bryophytes, of which mosses and liverworts are the most common.

After Colura, this was the second report of zoophagy among the liverworts.

Sphaerocarpos is a genus of plants known as bottle liverworts.

In addition to this taxon-based name, the liverworts are often called Hepaticophyta.

It is thought that liverworts evolved from green algae.

He described or recognized many species of liverworts.

He was an expert on the mosses and liverworts of North America.

Sullivant became the leading expert on mosses and liverworts of his time.

Such fungi increase the productivity even of simple plants such as liverworts.

Violent winds have blown down some spectacular lichens and liverworts.

As a rule, simple thalloid liverworts do not have structures resembling leaves.

Stomata are present in the sporophyte generation of all land plant groups except liverworts.

It is also perforated with pores resembling those of some liverworts.

Recent taxonomy places them separately in a division called the Marchantiophyta, or even the Antheroceratophyta.

Bryologists classify liverworts in the division Marchantiophyta.

They were once considered related to mosses and part of division Bryophyta, but more recently have been assigned their own plant division, Marchantiophyta.

They can be distinguished from liverworts (Marchantiophyta or Hepaticae) by their multi-cellular rhizoids.

Marchantiophyta (liverworts)

The wood is about 40 to 100% overgrown with Marchantiophyta, especially of the genera Nowellia or Cephalozia.

Although there is no consensus among bryologists as to the classification of liverworts above family rank, the Marchantiophyta may be subdivided into three classes:

In botany, "seta" refers to the stalk supporting the sporangium of a moss, hornwort or Marchantiophyta, and supplying it with nutrients.

Another Devonian fossil called Protosalvinia also looks like a liverwort, but its relationship to other plants is still uncertain, so it may not belong to the Marchantiophyta.

Crandall-Stotler, Barbara J. & Stotler, Raymond E. "Morphology and classification of the Marchantiophyta".

Many fungi (e.g. Calocera viscosa) and mosses are saproxylic or epixylic as well (e.g. Marchantiophyta) - some moss species completing their entire life-cycle on a single log.

Some dispersed, fragmentary fossils of disputed affinity, primarily spores and cuticles, have been found in rocks from the Ordovician Period in Oman, and are thought to derive from Marchantiophyta- or moss-grade fossil plants (Wellman et al., 2003).

He has written over 650 publications, mainly on the Asteraceae, mosses (Bryophyta), Marchantiophyta, and the long-legged fly family Dolichopodidae (describing over 200 new species and 6 new genera, such as Harmstonia and Nanomyina) and many other subjects.

Although the Rocky Mountain Region has no endemic vascular plant families and only one endemic Marchantiophyta family (Gyrothyraceae), it has many endemic genera (such as Sidalcea, Luetkea, Whipplea, Vancouveria, Lithophragma, Tellima, Tolmiea, Luina) and numerous endemic species.

It is estimated that there are about 9000 species of liverworts.
