Abstract
Abstract. Chromosome numbers are reported for 35 individuals of one of three species of Solidago L. sect. Multiradiatae (Semple) Semple & J. B. Beck from Canada and the United States: S. multiradiata Aiton. Identifications of nearly all vouchers for 101 previously published counts for S. leiocarpa DC., S. multiradiata, and S. spithamaea M. A. Curtis ex A. Gray were confirmed or revised following the delimitation of the section by Semple and Beck (2021). Diploids 2n = 18 occur over much of the range of S. multiradiata with tetraploids occurring in some areas of the range but unknown from others. The two narrowly distributed high Appalachian Mountains species are both polyploid: S. leiocarpa is tetraploid 2n = 36 in New Hampshire, and S. spithamaea is hexaploid 2n = 54 in North Carolina.
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.
