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

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
