Derek Anderson and Julie Fox present the latest in a long line of floristic studies published in The Michigan Botanist, in this case a flora of Interstate State Park, Wisconsin’s oldest state park, which is situated in the tension zone along the St. Croix River in northwestern Wisconsin. The authors take into account previous collections at the park as well as their own collections to provide a complete list of the park’s vascular flora as currently known. This is supplemented with a geological and human history of the area, along with a description of the various plant communities that occur in the park. This paper can be considered a companion piece to an earlier flora of Amnicon Falls State Park, which lies some 150 km to the northeast, near Lake Superior, authored by Paul Hlina, Derek Anderson, and Donald Davidson (The Michigan Botanist 47: 121–146). Indeed, the article in this issue provides a comparison of the floras of the two state parks and discusses how the differences arise from their differing geographical settings and floristic regions.

The second article in this issue is a collaborative effort by the members of a field botany course, co-authored by their teacher, Jordan Marshall. The authors studied three forest fragments in relatively close proximity to assess how the differences in species composition in canopy, midstory, and understory strata, as well as in certain factors such as species richness, canopy closure, leaf litter depth, and incidence of non-native species, are related to the different management histories and levels of protection of the three study sites.

Neil Harriman completes his series of reviews of the field guides written by Steve Chadde on various regions of the Midwest, including floras of the states of Wisconsin and Minnesota and of the Upper Peninsula of Michigan, as well as a guide to the ferns and fern allies of the north central United States. His earlier survey of six of Chadde’s wetland floras of various states of the Great Lakes region, as well as one for the entire region, appeared in the previous issue of The Michigan Botanist (52: 109–114).

The editor has provided a catalogue of floristic articles from throughout the whole 53 years of The Michigan Botanist from its inception to date in order to make this rich resource readily available to current readers and researchers. The issue is rounded out with two book reviews.
