Discussion:

This species is separated from Andreaea rupestris by its smaller size, imbricate, obtuse leaves, the lack or weak expression of dorsal papillae, and its smaller, non-porose upper leaf cells. The taxon has been treated as a variety, subspecies or synonym of A. rupestris, but most recently Murray (1987) maintained it at the specific rank. In Central America A. alpestris appears distinctive, but it cannot be critically evaluated because it is known from only a few collections. Murray (1987) considered the Central American collections of A. alpestris misnamed but offered no opinion on their identity. The Central American species appear to agree in all particulars with her 1987 treatment of Andreaea alpestris.
