Introduction. Whereas the capsule wall in liverworts is usually described as smooth, our discovery of deep schizogenous fissures in the unistratose walls in Haplomitrium appears unique to this earliest diverging liverwort genus and may have important implications for understanding the evolution of the stomatal toolkit in land plants. Methods. Sporophytes of Haplomitrium gibbsiae and H. mnioides were

The gravitropism of caulonemata of Pottia intermedia is described and compared with that of other mosses. Spore germination produces primary protonemata including caulonemata which give rise to buds that form the leafy moss plant, the gametophore. Primary caulonemata are negatively gravitropic but their growth and the number of filaments are limited in the dark. Axenic culture of gametophores results

Introduction. Aphanorrhegma (Physcomitrella) patens (Hedw.) Lindb. is an attractive model system for comparative analyses of leaf development because it evolved leaves (phyllids) independently to flowering plants, yet its genome contains homologues of many gene families that regulate angiosperm leaf development. In addition, A. patens phyllids are primarily a single cell layer thick, making it simple
