Abstract

Methods of macroevolutionary systematics as recently modified are explained and applied to the genus Anoectangium Schwägr. (Pottiaceae) in hyperoceanic areas of coastal northwestern North America. It was revealed that this area harbored species like those reported for the Himalayan region of northern India. Keys are provided for North American and Himalayan species of the genus. A macroevolutionary analysis, detailed in the Methods section, distinguishes and gives relationships between the species. There is strong Bayesian support for progenitor-descendant pairs and lineages. Anoectangium thomsonii Mitt. is considered a synonym of A. aestivum (Hedw.) Mitt. Anoectangium crassinervium Mitt. is transferred to Molendoa Lindb., under a nomen novum with A. handelii Schiffn. as a synonym. Anoectangium incrassatum Broth., related to the Asian A. clarum Mitt., is reported as a well-characterized species from the West Indies. Anoectangium stracheyanum Mitt. is re-lectotypified. Distinctions between A. aestivum and A. euchloron (Schwägr.) Spruce in the New World are clarified. Causal explanations in systematics are equated with entropy maximization in Shannon information analysis in the context of serial descent. A Pleistocene species pump hypothesis is advanced to explain the stenomorphic populations of species of the genus in eastern North America.

期刊介绍： The Annals of the Missouri Botanical Garden is a quarterly international journal primarily devoted to systematic botany and evolutionary biology. We encourage submissions of original papers dealing with significant advances in the taxonomy, phylogeny, biogeography, paleobiology, and evolution of plants, and in conservation genetics and biology, restoration ecology, and ethnobiology, using morphological and/or molecular characters, field observations, and/or database information. We also welcome reviews and papers on conceptual issues and new methodologies in systematics. Important floristic works will also be considered. Symposium proceedings discussing a broader range of topical biological subjects are also published, typically once a year. All manuscripts are peer-reviewed by qualified and independent reviewers.
