[Cinnamon fern, formerly known as Osmunda cinnamomea L. was recently placed in the genus Osmundastrum, which is now regarded as a sister clade to all other genera in the Osmundaceae. Reports from Labrador are based on a single sterile specimen, probably of Claytosmunda claytoniana, collected from an uncertain location in the Churchill River valley.]
