Discussion

The leaves of Aloina brevirostris are usually short, and cucullate with a reduced lamina; forms with larger laminae may be confused with A. rigida, but the synoicous condition and the cylindric capsules with a conical operculum are diagnostic. The latter species is dioicous, and has ovoid-cylindrical capsules with a long-rostrate operculum.
