The Bryophyte Chapter was formed on 30 May 2015. To make the Chapter healthy it is crucial that our people join the California Native Plant Society and affiliate with the Bryophyte Chapter as well as a local chapter.

If you want one of us to lead a moss walk or give a talk on bryophytes to your group, email a liaison (see Contacts page). Our coverage around the state is admittedly patchy, and we don't promise that we'll be able to get to your place in a timely fashion, but give us a try even if it seems to be a long shot. The at-large liaisons, the President, and the President Elect try to help out when they can.

At the base of the tree of life of land plants emerge four lineages: liverworts, mosses, hornworts, and vascular plants. The vasculars are the plants people are most familiar with—ferns, conifers, flowering plants, etc. The other three lineages are bryophytes. Vasculars have well developed tissues for conducting water and photosynthates, whereas bryophytes have simpler conducting tissues or sometimes none at all. In addition, vaculars have a life cycle dominated by the sporophytic phase, the stage of life that makes spores and that has two sets of chromosomes in its cells, whereas bryophytes have a life cycle in which the sporophyte lives out its whole existence growing on the gametophyte, the stage of life that makes eggs and sperm and has cells with one set of chromosomes. The green leafy parts of a moss that occupy a rotten log or a soil bank are gametophytic. Bryophytes tend to be small. They cannot move materials around very far internally and instead take them up directly across the surface of most cells. This has a profound affect on their biology. For instance, a moss can receive its nutrients from dust and aerially deposited ions, whereas a vascular receives its nutrients from root hairs and mycorrhizae. Bryophytes tend to be desiccation tolerant. Many can dry out completely, and after re-wetting they come back to life in minutes. Typically bryophytes also can grow from fragments, asexually. Almost any fragment of a moss could grow up to be a new plant given the right conditions. A fair fraction of bryophytes have more or less specialized asexual propagules. The bryophytes, however, are probably not a single branch on the tree of life. As such they are heterogeneous, and it is better to think of the mosses, the liverworts, and the hornworts separately.
