Bryoerythrophyllum jamesonii is an Andean species also found in southern Mexico and   Guatemala. It is a medium-sized species with oblong-lanceolate leaves having plane, dentate upper margins, and long-rectangular basal leaf cells. In Central America it can be confused with B. recurvirostrum or B. campylocarpum. Bryoerythrophyllum recurvirostrum differs from it in having leaf margins recurved to near the apex, and thin-walled, bulging basal leaf cells. Bryoerythrophyllum campylocarpum is a smaller plant than B. jamesonii and its leaves are less clasping. In addition, its costa at back is densely papillose, and its smooth basal leaf cells are  enlarged and bulging toward the inside but long, narrow, and firm-walled at the margins.

Mironia ehrenbergiana is very similar to B. jamesonii, but differs in having bistratose leaf margins.
