Discussion:

Bryoerythrophyllum inaequalifolium has ovate, broadly rounded, non-apiculate leaves, a costa that is thickened and densely papillose near the apex, entirely revolute leaf margins, quadrate to oblate basal leaf cells (at times short-rectangular near the costa at the extreme base), and dense clusters of irregularly shaped axillary propagula. The peristome of this species is exceptionally well-developed which perhaps accounts for its original placement in Barbula. Zander (1980) transferred it to Bryoerythrophyllum because of its reddish color, large, c-shaped papillae, and acid-base color reactions. The illustrations of B. inaequalifolium in Zander (1968) are excellent; in contrast, the leaves drawn in Sharp et al. (1994) are not representative of this species.
