Discussion
Brachyelytrum aristosum, like B. erectum, grows in moist woods and forests, but its primary distribution is more northern, extending from Ontario to Newfoundland, Minnesota, and Pennsylvania, and south through the Appalachian Mountains to the junction of Tennessee, North Carolina, and Georgia.
Some authors (e.g., Koyama and Kawano 1964) have called this taxon Brachyelytrum erectum var. glabratum.
As discussed under B. erectum, that name is a nomenclatural synonym of B. erectum sensu stricto. Nevertheless, most plants identified as B. erectum var. glabratum will be found to be B. aristosum.
