Discussion

Of conservation concern.

Rosulabryum andersonii was transferred from Brachymenium because it does not fit in the type section, which consists of tropical epiphytes with erect capsules. Rosulabryum andersonii is morphologically similar to several robust tropical species of Rosulabryum that have elongate, evenly foliate stems. Despite repeated searches, the population has never been relocated, and the species may be extinct. A specimen reportedly collected in 1988 from Mexico needs to be evaluated.
