An investigation of the diversity of Pluerocladula R. Grolle in North America.

The leafy liverwort Pleurocladula R. Grolle is generally accepted as being a monotypic genus. Through utilizing light microscopy and examining herbaria samples worldwide we have noticed that the North American populations of “Pleurocladula albescens (W.J. Hooker) R. Grolle” have a tendency to generate stoloniferous/flagelliform branches. Diagnoses of P. albescens in Europe and North America do not mention this anatomical characteristic within this species. In Schuster’s treatment of Pleurocladula in North America east of the hundredth meridian he went as far to say that stolons are lacking in Pleurocladula. This suggests that these North American populations in which we are finding individuals with stoloniferous/flagelliform may represent an undescribed species.
