Discussion

Brotherella recurvans resembles Pseudotaxiphyllum elegans (Hypnaceae) superficially, but is generally larger and has inflated alar cells and a toothed apiculus. Branches and main shoots of B. recurvans bear leaves of similar size and areolation, and branching tends to be irregular. The laminal cells are usually linear to sinuate-linear.
