Porellales is an order of liverworts. [1] [2]
Marchantiales is an order of thallose 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.
Metzgeriales is an order of liverworts. The group is sometimes called the simple thalloid liverworts: "thalloid" because the members lack structures resembling stems or leaves, and "simple" because their tissues are thin and relatively undifferentiated. All species in the order have a small gametophyte stage and a smaller, relatively short-lived, spore-bearing stage. Although these plants are almost entirely restricted to regions with high humidity or readily available moisture, the group as a whole is widely distributed, and occurs on every continent except Antarctica.
Jungermanniopsida is the largest of three classes within the division Marchantiophyta (liverworts).
The Chicago Cubs baseball club is an original member of the National League, established in 1874 or 1870. Here is a list of players who appeared in at least one regular season game beginning 1874.
Frullania is the only genus of liverworts in family Frullaniaceae. It contains the following species:
Haplomitriopsida is a newly recognized class of liverworts comprising fifteen species in three genera. Recent cladistic analyses of nuclear, mitochondrial, and plastid gene sequences place this monophyletic group as the basal sister group to all other liverworts. The group thus provides a unique insight into the early evolution of liverworts in particular and of land plants in general.
Pleurozia is the only genus of liverworts in the family Pleuroziaceae, which is now classified in its own order Pleuroziales, but was previously included in a broader circumscription of the Jungermanniales. The genus includes twelve species, and as a whole is both physically distinctive and widely distributed.
Haplomitrium is a genus of liverwort.
Pallaviciniales is an order of liverworts.
Jungermannia is a genus of leafy liverworts belonging to the family Jungermanniaceae. They have a worldwide distribution.
Anastrophyllum is a genus of liverworts belonging to the family Anastrophyllaceae.
Lepicolea is a genus of liverworts belonging to the family Lepicoleaceae.
