Discussion
Brachyelytrum erectum grows in woodlands, occasionally over limestone bedrock, and in moist woods and forests. It extends from Lake of the Woods, Ontario, east to Newfoundland, and in the United States from Minnesota to New England and south to the Gulf Coast and Florida.
Koyama and Kawano (1964), among others, treated Brachyelytrum erectum var. glabratum (Vasey) T. Koyama & Kawano as the northern taxon B. aristosum, but the holotype of B. erectum var. glabratum belongs to B. erectum sensu stricto. This means that, nomenclaturally, B. erectum var. glabratum is a synonym of B. erectum, although most of the specimens identified as var. glabratum belong to B. aristosum.
