The season was a significant one for study of the flora of the region of the University of Michigan Biological Station because of the opportunity for early spring collections. During two week ends in early May, a variety of habitats were visited in Emmet and Cheboygan Counties, and duplicate sets collected for the University Herbarium and the Biological Station Herbarium. Field notes and mass collections of Primula "intercedens’, were made May 12, at its prime.
